Hello. Would you like to briefly introduce yourself to our readers?

I am Daniel. OpenStreetMap mapper for 1339 days now. I’m twenty-something and I really like the winters.

How and when did you get to know OpenStreetMap?

Back in 2017 I was looking for a decent alternative to the old maps but didn’t find one. Instead i’ve found a great tool to create a map for myself and for the others.

How do you use OpenStreetMap?

I do use OpenStreetMap as the map when I hike or travel. I also learned many new things about the Earth while mapping. Sometimes I just stare at the map. This is fun too.

What kind of contributor are you and in which area do you map?

Mapper. Mostly I map Komi Republic, yet sometimes I do other parts of the world too.

What are you mapping? Do you have a specialisation?

Everything is important, so I trying to map every single detail within a certain limit, resolution. Mostly, natural features.

What is your greatest achievement as mapper?

That thing, what caught your attention is probably it.

Why are you mapping? What motivates you?

I like the meditative deconstruction of complex real world objects into an abstract simple shapes. It brings me peace. I also like the map that i’m getting out of that, but this is a side benefit.

Do you have any ideas to expand the OpenStreetMap community, to motivate more people to contribute?

OpenStreetMap should become more user friendly to grow. In my opinion, the important thing is not to keep attracting new people but make those who came by themselves stay.

Do you have contact with other mappers?

Sure! We communicate via Messenger. Unfortunately, very few people map the same area that I do, so I am one by myself.

What is in your view the greatest strength of OpenStreetMap?

Freedom. In OpenStreetMap, anyone free to map or edit whatever features they want. It is really pleasant and it sets the right tone to the process.

What are the largest challenges for OpenStreetMap?

Lack of level of details consistency. One area might get mapped so well that it’s not really necessary to look off the screen while walking, while the other nearby area might not contain a vital information such as a river or a wall, blocking your way. And there is no way for the end user to know that beforehand.

How to do stay on top of news about OpenStreetMap?

You read about OpenStreetMap, you talk to the different mappers.

To conclude, is there anything else you want to share with the readers?

landcover tag is great!

Thank you, Daniel, for this interview.

Sa page d’accueil et sa page de contribution.

Bonjour. Voudrais-tu te présenter brièvement à nos lecteurs ?

Je m’appelle Daniel. Je suis cartographe OpenStreetMap depuis 1339 jours maintenant. J’ai une vingtaine d’années et j’aime beaucoup les hivers.

Comment et quand as-tu découvert OpenStreetMap ?

En 2017, je cherchais une alternative décente aux anciennes cartes, mais je n’en ai pas trouvé. Au lieu de cela, j’ai trouvé un outil formidable pour créer une carte pour moi et pour les autres.

Comment utilises-tu OpenStreetMap ?

J’utilise OpenStreetMap comme carte lorsque je fais de la randonnée ou que je voyage. J’ai aussi appris beaucoup de nouvelles choses sur la Terre en cartographiant. Parfois, je me contente de regarder la carte. C’est aussi amusant.

Quelle sorte de contributeur es-tu et dans quelle région cartographies-tu ?

Un mapper ! Je cartographie surtout la République de Komi, mais il m’arrive aussi de cartographier d’autres régions du monde.

Que cartographies-tu ? As-tu une spécialisation ?

Tout est important, alors j’essaie de cartographier chaque détail dans une certaine limite, une certaine résolution. Principalement, les caractéristiques naturelles.

Quelle est ta plus grande prouesse en tant que contributeur ?

Cette chose, qui a attiré ton attention, c’est probablement ça.

Pourquoi cartographies-tu? Qu’est-ce qui te motive ?

J’aime la déconstruction méditative d’objets complexes du monde réel en formes simples et abstraites. Cela m’apporte la paix. J’aime aussi la carte que j’en tire, mais c’est un avantage secondaire.

As-tu des idées pour élargir la communauté OpenStreetMap, pour motiver plus de gens à contribuer ?

OpenStreetMap devrait devenir plus convivial pour se développer. A mon avis, l’important n’est pas de continuer à attirer de nouvelles personnes mais de faire en sorte que ceux qui sont venus d’eux-mêmes restent.

As-tu des contacts avec d’autres contributeurs ?

Bien sûr ! Nous communiquons par Messenger. Malheureusement, très peu de gens cartographient la même région que moi, donc je suis seul.

Quelle est, selon toi, la plus grande force d’OpenStreetMap ?

La liberté. Dans OpenStreetMap, chacun est libre de cartographier ou de modifier les caractéristiques qu’il souhaite. C’est vraiment agréable et cela donne le bon ton au processus.

Quel est le plus grand défi pour OpenStreetMap ?

Le manque de cohérence au niveau des détails. Une zone peut être si bien cartographiée qu’il n’est pas vraiment nécessaire de regarder hors de l’écran en marchant, tandis que l’autre zone voisine peut ne pas contenir une information vitale telle qu’une rivière ou un mur, bloquant votre chemin. Et il n’y a aucun moyen pour l’utilisateur final de le savoir à l’avance.

Comment restes-tu à jour par rapport à l’actualité d’OpenStreetMap ?

Lire sur OpenStreetMap, parler aux différents cartographes.

Pour conclure, y a-t-il encore quelque chose que tu voudrais dire au lecteur ?

Le tag landcover est génial !

Merci, Daniel, pour cette interview.

Zijn homepage en zijn bijdrager pagina.

Hallo. Wil je jezelf even voorstellen aan onze lezers?

Ik ben Daniel. OpenStreetMap-mapper sinds nu 1339 dagen. Ik ben een twintiger en ik hou echt van de winters.

Hoe en wanneer heb je OpenStreetMap ontdekt?

In 2017 was ik op zoek naar een fatsoenlijk alternatief voor de oude kaarten, maar ik vond er geen. In plaats daarvan heb ik een geweldige middel gevonden om een kaart te maken voor mezelf en voor de anderen.

Hoe gebruik je OpenStreetMap?

Ik gebruik OpenStreetMap als kaart wanneer ik wandel of reis. Ik heb ook veel nieuwe dingen geleerd over de Aarde terwijl ik in kaart breng. Soms staar ik gewoon naar de kaart. Dat is ook leuk.

Wat voor soort bijdrager ben je en in welk kaartgebied map je?

Een mapper! Meestal map ik in de Republiek Komi, maar soms ook andere delen van de wereld.

Wat ben je in kaart aan het brengen? Heb je een specialisatie?

Alles is belangrijk, dus probeer ik elk detail binnen een bepaalde limiet of resolutie in kaart te brengen. Meestal, natuurlijke kenmerken.

Waar ben je het meest trots op als mapper?

Dat ding zijn (bijdrager pagina !), wat je aandacht trok is het waarschijnlijk.

Waarom breng je het in kaart? Wat motiveert je?

Ik hou van de meditatieve deconstructie van complexe objecten uit de echte wereld in een abstracte eenvoudige vorm. Het brengt me tot rust. Ik hou ook van de kaart die ik daarvan krijg, maar dat is een bijverdienste.

Heb je ideeën over hoe we de OpenStreetMap-gemeenschap kunnen uitbreiden of meer mappers kunnen motiveren?

Om te groeien, zou OpenStreetMap gebruikersvriendelijker moeten worden. Het belangrijkste is volgens mij niet om steeds nieuwe mensen aan te trekken, maar om ervoor te zorgen dat degenen die uit eigen beweging komen, blijven.

Heb je contact met andere mappers?

Zeker! We communiceren via Messenger. Helaas zijn er geen andere mensen die hetzelfde gebied in kaart brengen. Ik ben de enige in mijn streek.

Naar uw mening wat is de grootste kracht van OpenStreetMap?

Vrijheid. In OpenStreetMap is iedereen vrij om te mappen of te bewerken wat ze maar willen. Het is echt aangenaam en het geeft de juiste toon voor het proces.

Wat is de grootste uitdaging voor OpenStreetMap?

Een gebied kan zo goed in kaart gebracht worden dat het niet echt nodig is om op het scherm te kijken terwijl je loopt, terwijl het andere nabijgelegen gebied misschien geen vitale informatie bevat zoals een rivier of een muur, die je weg blokkeert. En er is geen manier voor de gebruiker om dat op voorhand te weten.

Hoe blijf je op de hoogte van het OpenStreetMap-nieuws?

Lezen over OpenStreetMap, praten met de verschillende mappers.

Om af te sluiten, is er nog iets dat je zou willen vertellen aan de lezer?

De tag landcover is geweldig!

Dank je, Daniel, voor dit interview.

Introduction 

IRDP YouthMappers is the group of students from the Institute of Rural Development Planning engaging in the provision of information related to the Geographical Information System (GIS).

This chapter was established in 2017 at IRDP. It is engaging in exploring various skills and technology which are related to their field and in one way or another can be helpful to their community.

Mnadani Community Mapping Project

IRDP YouthMappers Team formulate and conduct this project so as to reveal and identify various social, physical and environmental problems faced by the people from Mnadani Ward. With Micro Grant from OMDTZ, help IRDP YouthMappers Team to perform the following:

• Track and address challenges faced by the Mnadani Community.
• Capacity building to Students and Community Mappers.
• Community Awareness and Participation.

Contribution at State of The Map Africa

During State of The Map Africa @Shabani Magawila as the speaker representing IRDP YouthMappers got the chance to host Swahili Channel at OSM Mapathon on 20/11/2021. On 21/11/2021 also had a session to describe Mnadani Project which was sponsored by OMDTZ.

Date	Activity	Description
20/11/2021	OSM Mapathon	Hosting Swahili Channel in OSM Mapathon
21/11/2021	Mnadani Community Mapping Project	Speaker at elaborating about Mnadani Community Mapping Project

But also during State of the Map Africa, I got the chance to participate in other sessions conducted with different organizations and YouthMapper Chapters. Through State of The Map Africa, I learned much about how other Chapters and Organizations perform their works and projects.

Notes from the event

Although we have problems and challenges in our communities, we surely need to find ways and techniques to solve those problems.

Therefore, we need to be involved in formulations of Projects and technologies which have impacts on the development of a community either socially, economically, or Environmentally. Examples of the projects and technologies:

1. Agricultural and Food Processing Projects

During the event I learned much from Agrithamani and OMDTZ through their projects.

THANKS, SEE YOU 2022!

Es ist schon einige Zeit vergangen seit ich mit OSM und Mapping angefangen habe. Landnutzung war damals noch kein Thema, sehr viel von der Karte war einfach nur weiß. Ich zog los mit einem GPS-Empfänger und einer digitalen Kompaktkamera, um Straßenschilder zu fotografieren und habe Straßengerippe eingezeichnet, heute nennt man das Craftmapper. Fotos per timestamp zu korrelieren war in JOSM noch nicht eingebaut, dafür hat’s noch ein Plugin gebraucht.

Später war dann schon eine Menge da und ich hab nur noch sehr wenig gemacht, weil es sich gefühlt nicht mehr lohnte, ein paar Notizen mit nach Hause zu nehmen und mit JOSM zu pinseln.

Es ist noch nicht so lange her, dass ich im Fediverse einen Kurzeintrag las, der grob sagte, auf dem Bild seien mindestens 20 Punkte in StreetComplete enthalten. Dann hab ich mir das angeschaut und spiele es tatsächlich gelegentlich, weil man damit echt viel ergänzen kann, wenn man nebenan steht. Mehr oder minder gleichzeitig kam dann noch Vespucci mit aufs Telefon, denn damit kann man die ganzen Sitzbänke, Mülleimer, Hydranten, Bäume etc. einzeichnen, die noch nicht da sind, und all die Telefonzellen löschen, die die Betreiber mittlerweile abgebaut haben.

Die Auflösung der GPS-Empfänger ist im Kleinen eher so mittel, vor allem, wenn eine Zeile Häuser da rumsteht, die alle so unter 10 Meter breit sind und in den OSM-Daten oft nichtmal richtig eingeteilt sind, weil die Dächer zu ähnlich waren von oben. Für solche Dinge habe ich noch keine rechte Lösung.

Für den Schluss bleibt noch die Frage der Fragen: Wenn ich einen Mülleimer einzeichne, wo keiner ist, kommt dann die Stadt und stellt einen auf?

Я полностью прочитал ветку обсуждений над дворовыми проездами. Эта тема все еще имеет проблемы: она плохо объяснена на соответсвующей странице в вики, она плохо объяснена на других страницах, которые упоминают дороги. Как я понял: Жилые территории, обозначенные и не обозначенные знаком 5.21, то что мы называем дворовыми проездами и прилегающими территориями мы обозначаем так:

highway=service living_street=yes

Если во дворе есть более “главная” дорога (ее могут называть “стволовой”), то можно применить такую схему:

highway=unclassified living_street=yes и добавлять для второстепенных дорог во дворах (дороги, которые называют “нестволовыми” проездами): highway=service living_street=yes

В дурацком случае, когда жилая зона имеет название: highway=residential living_street=yes

Сейчас хочу изучить обозначение парковок вдоль дорог. Эта тема достаточно неочевидно рассказана, чтобы с поверхностного просмотра страницы в вики я не смог сразу взять и начать картографировать.

The best part of being an OSM editor is being able to write in my diary. I hope the feed picks this entry up.

My 214 Mapping Days of 2021

At the beginning of the year 2021, one of my targets was to upload a changeset at least every day until the end of the year. However, I have not managed to hit my target. Nevertheless, this year still emerges the year with my highest number of contribution days.

With my GIS background, contributing to OpenStreetMap has become one of my hobbies because the efforts invested in adding features to the map are reflected in the number of humanitarian challenges that are being solved through the availability of Open Spatial Data. Amidst all the challenges like low internet connectivity, expensive data bundles, limited access to digital devices, and others, the inspiration is derived from the support and opportunities that the OpenStreetMap Uganda and Humanitarian OpenStreetMap Team (HOT) has provided to the OSM Communities in Uganda. We appreciate.

My SOTMA Experience:

Earlier this year, I submitted my proposal to speak at the State of the Map Africa Virtual conference and I was so much excited when my proposal was accepted and given an opportunity to speak at the conference. To be honest, the year has been full of excitement, learning, contributions but also sharing information on what the OpenStreetMap Uganda Community has been doing over the past years. The OpenStreetMap Uganda Community gave me an opportunity to spearhead a number of community-driven projects and, at the same time to share with the rest of the world what we have achieved through those projects by presenting at the State of the Map Africa Conference. Besides the opportunity to present the Remote Mapping & Photo Mapping New Cities project, I also participated in a number of lightning talks at the HOT Summit and organized a watch party in Kampala where the rest of the community members were able to stream the conference on the big screen.

I have been able to learn a lot from the presentations from the different speakers and copied a number of ideas that will be scaled to fit my community. A lot of thanks to the organizing committee of the State of the Map Africa conference, and all the partners that contributed to making SOTMA 2021 a successful conference.

The OpenStreetMap Community of South Sudan, was launched on 26th.Nov.2021, in an event that brought together Government agencies like the National communication Authority, Companies like East Africa GoGreen, Academia like The University of Juba and among other individuals, this launch event was the commence point of the upcoming programs of OSM South Sudan and it strives to achieve its goal of facilitating the creation, and use on OpenStreetMap data, this shall be made possible by the couple of partnerships OSM South Sudan is looking with the Government and other entities who shall either be data users or contributors, though the collaboration with other HOT and the Open Mapping hub, East and Southern Africa has come handy in building and pushing for success of the community. OSM South Sudan is now in the process of collaborating with the NCA to map and solve address issues in Juba.

I suspect a JOSM edit.

Our long-running OpenStreetMap interview series continues with today with a look at the state of OpenStreetMap in Korea. We spoke with Dongha Hwang, a very active member of the local community about his perspective on how the map and community are developing.

1. Who are you and what do you do? What got you into OpenStreetMap?

I’m Dongha Hwang, a OpenStreetMap user (username LuxuryCoop), a editor of WeeklyOSM Korean edition, serving in the Republic of Korea Air Force (I will be discharged from the military in a year and 2 months.) I got to know OSM at January 2017, when Pokémon GO is launched in South Korea, with OpenStreetMap instead of Google Maps. It is because the government prohibits to take maps made by them out of South Korea, so they introduced a good solution, switching to OSM not made by only the government, but by many volunteer community. From that time I’ve been contributing free and open geospatial dataset which anybody can use any purpose.

2. What would you say is the current state of OSM and the OSM community in Korea?

In some aspect, the state of OSM in South Korea is almost complete, but in the other, unfortunately, it is very poor. The majority of residential roads are mapped with ‘name’ tag. In addition, some railroad enthusiasts make railroad infrastructures in Korea OSM (not only South, but also North!) very detailed. On the other hand, regardless of whether you are on a urban or a rural OSM, you can see buildings rarely, except apartments. Even in the capital area of South Korea, in which 25 millions (i.e. half of population of South Korea) are living!

Fortunately, some heavy mappers have been mapping hundreds of buildings with addresses every day. I believe that all of Korean find their house on OSM someday!

For a long time, mappers contributes OSM of South Korea individually, although many foreigners (and few Koreans) had discussed for the better map. However, now the osmKorea Telegram channel is very active OSM Korea community, in which many Korean and people from the other countries are talking! I recently made a website and named a Facebook group OpenStreetMap Korea, because Telegram is far more private platform than Facebook, so a Facebook group can easily promote us and our activities to non-OSMers. Actually it has been attracting members on the OSGeo Korean chapter.

3. What are the unique challenges and pleasures of OpenStreetMap in Korea? What aspects of the projects should the rest of the world be aware of?

All map services in South Korea do not display military facilities, prisons, and water purification plants. However, since OpenStreetMap does, the media often criticizes it. I think this is one of the reasons South Koreans rarely use OpenStreetMap. (By the way, I recently made a tile server - tiles.osm.kr - and its source database - tiles.osm.kr/download - without military bases and security areas for OSM Korea)

Also, the quality of Korean map services provided by Naver or Kakao in South Korea is very high (Street View, traffic situation, rates of restaurants, …), so people don’t feel the need for OpenStreetMap much. So, while I promote OSM as a map, but also I used to say that unlike Naver Map and Kakao Map, OSM can provide information about bench location and accessibility, and emphasizes its role as a “geographic database” that can be used in various fields such as paper research.

Meanwhile, I often enjoy mapping buildings to OpenStreetMap, feeling proud to see OSM that had only roads becoming like a commercial map. When I don’t contribute to OSM, the other mapper in South Korea are contributing to OSM by mapping buildings and amenities on the other place.

4. What is the best way to get involved in the local community? Where does the community meet and hang out (physically and digitally).

We have never met offline or even held a mapping party online. However, as mentioned above, we are active in OSM Korea Telegram channel, so if you want to discuss about Korea OSM, don’t hesitate, come on here. If you have a Facebook account, you can register the osmKorea Facebook group so that receive news about Korea OpenStreetMap community.

5.What steps could the global OpenStreetMap community take to help support OSM in Korea?

Neither South Korea nor North Korea OSM has many buildings. In South Korea, only 7.6% of all buildings are mapped in OpenStreetMap. The Korean government distributes building footprints nationwide freely, but they are not available for OSM at all due to laws that prohibit the export of data from the Ministry of Land, Infrastructure and Transport to foreign countries (including OSM servers in Europe.)

Hand-tracing of 7 million buildings in South Korea (and many buildings in North Korea) is a very challenging task. If a AI-based building footprint dataset is available and people are in charge of review and modification, the speed of contribution can be very fast.

I’m sorry that I’m too obsessed with buildings. Of course, information such as roads, addresses, and stores is also very important. However, buildings (and landuse) make OSM “looks like a map.” Members of communities related to OSM, such as the Pokémon Go community, say that no matter how detailed the road is, OpenStreetMap is poor “because there are no buildings.”

Until now, Korea OpenStreetMap has relied on volunteers who are proud of the changes in roads and buildings from empty spaces. However, in order to grow and promote the community, it is necessary to emphasize the strengths of OSM compared to commercial maps. This is especially true in South Korea, which is very familiar with commercial maps.

6. This year OSM celebrated its 17th birthday, so we are well into the “teenager” stage of the project. But what will it look like when it “grows up”? Where do you think the project will be in 10 years time, both globally and in Korea specifically?

Korea OSM in 2011 was incomparably inferior to now. It was difficult to find features other than major roads. However, almost all roads and railroads are mapped in great detail in the current OSM, and buildings are being added at a rapid pace, although not many.

South Korean users of Nimby Rails, one of the games using OSM, enjoy laying railroads on detailed road maps of South Korea and even North Korea (a detailed NK map is rare.) If It had used OSM data 10 years ago, they would not have been so satisfied with the map. Once OSM is detailed, it is used in wider domain, more people get to know OSM, and they contribute to OSM, it becomes more detailed…

I believe that in 10 years, OSM will be used not only in the commercial sector but also in the public sector (which prefers ‘made in Korea’ much more than open sources.) It’s a pretty bold prediction, but no one knows about the future, right?

Many thanks, Dongha, for this look at OpenStreetMap Korea, and all your work to build the community! As you note, the map has come a long way in the past few years. Hopefuly the progress will rapidly continue.

happy mapping,

Ed

Please let us know if your community would like to be part of our interview series here on our blog. If you are or know of someone we should interview, please get in touch, we’re always looking to promote people doing interesting things with open geo data.

As a Crowd2Map intern I had the opportunity to attend the conference #StateOfMap2021, it was a unique experience where for the first time I could see many experts from various areas related to data in one place, I did not know that the mapping area was too large.

Well, many sessions marked me but in particular those involving development of solutions using programming language, I hardly knew that with the knowledge I have in Python and database could do a lot of things with data, for me it was a wake-up call. It was from this awakening that I decided to explore further this area of development of solutions using data, research more about what I can do with the mapping data here in Mozambique to help in the development. With regard to networking it was possible to create networking, for an exchange of experience in the area, where it was possible to have a view also of what I can do mapping.

Congratulations to the whole team, for the beautiful organization, was all very well organized from the sessions until the presentations made, it was very good to know that there are so many people or a united group in the area of mapping and for the development of solutions for society. One of the recommendations that maybe could leave is that next time presentations are made all in English so that we can all watch all the sessions, or to the sessions in a language other than English could be put subtitles do not know if is possible or the slide could be translated into English and then sent to the participants.

Things I’ve figured out (possibly incorrectly) in my first week of mapping, since I discovered StreetComplete and got addicted… Don’t worry, in two or three weeks I’ll simmer down, LOL

• It’s better to mark a store (with website etc) as a point, and mark the building footprint (area) separately as “retail premises”. This way if the building footprint gets adjusted, the shop marker is still there; also the shop marker can be moved if the store relocates, as they often do

• There’s no “medicare_bulk_bill=all/available/none” tag yet for doctor’s clinics, although this is key information which really helps when looking for a GP (doctor). Also, none of the GP’s in my whole town were listed at all.

• In order to place advisory speed limit zones - like around bends - you need to split the road into sections and add max_speed:advisory=xx

• A “living street” in StreetComplete is a pedestrian shared zone in Australia, and usually has a 10 or 20 km/hr limit (I have mostly only seen them in caravan parks). I have been marking residential streets as “slow zone: 50km/hr” (because I need the 50 to show up on my GPS as a reminder if possible).

• When marking the location of a tree, there’s no tag (at least, not showing in iD) for species. This would be helpful when marking some trees, e.g. locally Ficifolia are a significant species, as are Norfolk Island Pines.

• old historical buildings and routes belong on the open history map, not the open street map.

• there are many, many major buildings and stores missing in my town!

• Daycare centres are probably tagged as ‘nursery/creche’?

• There’s already an excellent CC-BY 4.0 Victorian government data set that includes all the roads and buildings already, but it needs importing and that hasn’t been done yet because nobody with the skills has had a go at it.

• In some places, four or five separate buildings that touch one another are all drawn as one building.

• It’s amazing the things you notice when looking closely at maps. While checking the map, I saw a building that I didn’t recognise. It was right beside an intersection I have driven through many times a week for a few years - but still, I had no recollection that there was anything there at all. I had to go and look, and there it was!

• updating OpenStreetMaps is addictive, and I really need to pace myself. I am having far too much fun…

Зарылся в обрисовку Смоленщины на карте OSM.

Хотя мерзкий mapcraft поломался и не позволяет логиниться и резервировать на себя куски пирога (автор сайта пока молчит, но я ему написал и надеюсь, что он скоро починит проблему), это не мешает загрузить сетку с номерами ячеек и обрисовывать произвольно выбранную ячейку. При таком количестве ячеек и таком “изобилии” рисующих, вероятность попасть на уже взятый кем-то кусочек - исчезающе низкая. :) В общем, рисовать можно.

Очень интересно, сколько времени должна занять обрисовка одного гексагона диаметром 10км и как будет выглядеть результат. :) С одной стороны, при выборе такого диаметра сетки, гексагонов получилось сравнительно небольшое количество (около 400). С другой стороны, если взялся, твой гексагон не скоро тебя отпустит, работы там получается точно не на пару часов.

За три рисовальных дня насыпал, кажется, больше точек, чем за весь свой предыдущий мапинг. :) Больше пяти тысяч точек. Замаплена, по ощущению, примерно треть от гексагона, и хотя мапинг таких штук сильно затягивает, замапить всё за один раз (и даже за один день) - совершенно нереально.

Зрительная кора адски греется, примерно так же, как в игре mapswipe, где надо дрессировать нейросетку HOT OSM, отделяя квадратики, в которых есть искомые объекты (дороги или здания), от квадратиков, в которых их нет. Есть ощущение, что весь этот ихний мапсвайп с мапингом Ботсваны или Афганистана - это была просто тренировка в рамках подготовки к мапингу лесов Смоленщины. В мапсвайпе есть разные уровни сложности (хотя об этом никто до начала игры не говорит). Некоторые задачи решаются на изи. А некоторые задания уровня “завали босса”, с адски зашумлённой картинкой, на которой найти домики среди раскиданных камней или баобабов не проще, чем панду среди штурмовиков.

Смоленщина по сложности получается что-то среднее. Это точно не прохождение мапсвайпа на харде, но в некоторых случаях найти опушку и понять, в каком месте лес переходит в болото - не самая тривиальная задача. Лес тут далеко не всегда кончается внезапно.

Сильно помогают навыки распознавать и рисовать гидрологию, в т.ч. с подсматриванием общей трассировки по генштабу. После того, как получил представление о трассировке рек в лесу, становится понятнее, где тут могут возникать болота, и тогда эти болота лучше видно.

Очень здорово прокачался в лоскутном зонировании при помощи инструментов JOSM “Разрезать смежные линии” из состава плагина UtilsPlugin2 и плагина RelToolBox. Это когда объекты простенькие, можно позволить себе прокликать границу между ними два раза - сначала для одного объекта, потом поверх тех же точек - для другого. А когда общая граница имеет несколько сотен точек, такой подход становится непозволительной роскошью, поэтому рисовать лес иначе как мультиполигонами и методами лоскутного зонирования - никак невозможно. Мысль о том, что создаваемые объекты практически неремонтопригодны для тех маперов, которые не владеют двумя указанными инструментами (а это абсолютное большинство) - не радует, но другого выхода вообще нет. https://www.openstreetmap.org/#map=13/55.4637/34.3082

I was part of the volunteers in the SOTM preparation for the virtual conferences, I have always preferred to reserve a particular space equipped enough to participate during the conference. I must say due to traveling and preparing for Africa GIS conference calls, I didn’t prepare such an environment to attend this conference but I used any of the opportunity I have to attend. In spite of all, I had quality time to join in at some scheduled talk sessions and networking sessions with participants from other parts of the world at large.

One of the amazing talk sessions I learned most was a talk on “Community mapping to improve flood preparation in Nigeria” which was facilitated by Sharmila because in some areas in Nigeria are facings water challenge and other areas are facing water scarcity. The talk exposed the different most flooded areas affecting communities and it also presented a solution by using mapped buildings, roads, and water areas edits on OpenStreetMap. The two areas stated earlier must solve both challenge simultaneously. The facilitator also recommended other solutions that could solve the flooding problems.

During the event, I networked with GUY a member of OpenStreetMap in. Cote d’Ivoire and the interesting part was that we meet at Africa GIS conference in person such an amazing network session to talk more and take pictures together. We discussed the SOTM conference, talk about his country shared our experience in contributing to OSM, and also exchanged contacts. At the Network break session, I also had a call with Becky Chandiru, who was one of the facilitators during the HOTOSM Data quality internship 2020. We made use of the period to connect well enough and shared some ideas with each other.

I really had a great time and an insightful learning period at the SOTM Conference 2021, even though I didn’t have much time to spend on it but it was amazing. Kudos to all the organizers, volunteers and the participants nice have you all. See you all physical next year SOTM AFRICA.

As a Rwandan young woman a mother and a teacher it was an honor to attend STATE OF THE MAP Africa for the second time , it was a great experience to attend such huge platform online after pandemic loneliness. I was excited to see and to hear from other experienced OSM communities , it was fun! I was impressed to my fellow Rwandan community member joining for the first time and Youth Mappers as well, the Team is now hungry and willing to learn more about advanced mapping on OSM.

https://twitter.com/Crowd2Map/status/1463873169618522123?t=OfpGgqBXHmfbSxEHFtrHJg&s=19 Local communities especially in rural areas including marginalized groups need also to understand these open source tools which have proved to be cost effective and reliable in addressing challenges in several sectors. From the presentation from Janet chapman, these groups are called digital champions. As organizations and groups in OSM, we should cultivate many digital champions, and from this we invest our efforts to the right people

O Instituto Brasileiro de Geografia e Estatística (IBGE) lançou no último dia 27 de outubro a Base Cartográfica Vetorial Contínua do Estado do Rio Grande do Sul na escala 1:100.000, na qual 1cm equivale a 1km no terreno. Esse é o quinto conjunto de dados geoespaciais vetoriais lançados pelo Projeto BC100, para mapeamento das 27 unidades da federação nessa escala. Além do Rio Grande do Sul, já estão totalmente mapeados os estados de Goiás, Espírito Santo, Sergipe e o Distrito Federal.

As principais aplicações dessa base envolvem programas de governo com enfoque territorial, análises que demandem uma visão de conjunto das Unidades da Federação, bem como subsídio para a representação de aspectos temáticos – sociais, econômicos e ambientais – do território. É um documento cartográfico básico para o planejamento setorial de obras de infraestrutura como energia, transporte, comunicações, entre outros.

A publicação da Base oferece à sociedade um mapeamento planimétrico digital, através de uma base cartográfica contínua e compatível com os requisitos de precisão do Sistema Cartográfico Nacional (SCN) e adequada aos padrões e normas da Infraestrutura Nacional de Dados Espaciais (INDE).

Reprodução da Base Cartográfica do Rio Grande do Sul O produto foi elaborado utilizando como insumo imagens de satélite cobrindo todo o território gaúcho, dados levantados por pesquisas do IBGE, a cartografia oficial do estado (Base Cartográfica do Estado do Rio Grande do Sul em escala 1:25.000, lançada pela Secretaria do Meio Ambiente e Infraestrutura), e informações de órgãos parceiros.

“Desta vez, tivemos um grande desafio. A BC100_RS foi inteiramente produzida em regime de teletrabalho”, explica Juliane Silveira, gerente de Geodésia e Cartografia da Unidade Estadual de Santa Catarina do IBGE. “Em março de 2020, iniciamos o teletrabalho emergencial, em razão da pandemia. Conforme o planejamento teríamos de começar esse trabalho em abril. Em menos de um mês, adaptamos todo o processo de produção, que ocorria dentro da rede do IBGE, em banco de dados consolidado, para um regime descentralizado, exigindo esforço redobrado da equipe. Esse projeto quebrou paradigmas da produção cartográfica do IBGE e o resultado é mais um produto com a mesma marca de excelência”, complementa.

Essa base digital está em formato livre (Shape File, GeoPackage e dump do banco PostGis), para utilização em Sistemas de Informação Geográfica, sendo compatível, inclusive, com softwares livres e gratuitos, e pode ser acessada aqui e por meio de geosserviço, via Plataforma Geográfica Interativa do IBGE.

“Vemos um grande benefício para quem necessita de informações das regiões mais afastadas dos grandes centros urbanos”, comenta Juliane, enfatizando que as zonas rurais são as mais beneficiadas por esse mapeamento, pois sofrem com “apagão” de dados. “Tentamos minimizar esse problema trazendo a mesma densidade de informação tanto para zonas urbanas quanto rurais”, afirma a gerente.

A modelagem segue a norma vigente no sistema de referência SIRGAS2000 e as Especificações Técnicas para a Estruturação de Dados Geoespaciais Vetoriais na versão 3.0 (ET-EDGV 3.0), contemplando classes de 13 das categorias de informação previstas: Estrutura Econômica; Energia e Comunicações; Hidrografia; Limites e Localidades; Relevo; Sistema de Transporte; Sistema de Transporte/ Aeroportuário; Sistema de Transporte/ Dutos; Sistema de Transporte/ Ferroviário; Sistema de Transporte/ Hidroviário; Sistema de Transporte/ Rodoviário; Classes Base do Mapeamento Topográfico em Grandes Escalas; e Edificações.

O produto apresenta ainda a lista dos nomes geográficos no formato CSV, para serem visualizados em ambiente SIG, onde é possível localizar, através de suas coordenadas geográficas, todos os nomes geográficos que integram a base, representados por pontos. Os nomes presentes nas listas estão associados, além de suas latitude e longitude, às respectivas categorias e classes dos elementos representados.

Informações mais detalhadas sobre a base cartográfica estão disponíveis na nota técnica que acompanha o produto, disponível aqui. A BC100_RS também pode ser acessada através do Geoportal da INDE e seus metadados podem ser encontrados no Catálogo de Metadados do IBGE.

IBGE launches new cartographic base of Rio Grande do Sul

https://metadadosgeo.ibge.gov.br/geonetwork_ibge/srv/por/catalog.search#/metadata/59febe10-2da6-42c8-93c9-52db0a53385d

The Brazilian Institute of Geography and Statistics (IBGE) launched last October 27th the Continuous Vector Cartographic Base of the State of Rio Grande do Sul in a scale of 1:100,000, in which 1cm is equivalent to 1km on the ground. This is the fifth set of vector geospatial data released by the BC100 Project, for mapping the 27 states at this scale. In addition to Rio Grande do Sul, the states of Goiás, Espírito Santo, Sergipe and the Federal District are already fully mapped.

The main applications of this base involve government programs with a territorial focus, analyzes that demand an overall view of the Federation Units, as well as subsidies for the representation of thematic aspects – social, economic and environmental – of the territory. It is a basic cartographic document for the sectorial planning of infrastructure works such as energy, transport, communications, among others.

The publication of the Base offers society a digital planimetric mapping, through a continuous cartographic base compatible with the accuracy requirements of the National Cartographic System (SCN) and adequate to the standards and norms of the National Spatial Data Infrastructure (INDE).

The product was prepared using as input satellite images covering the entire state of Rio Grande do Sul, data collected by IBGE surveys, the state’s official cartography (Cartographic Base of the State of Rio Grande do Sul in 1:25,000 scale, launched by the Department of the Environment and Infrastructure), and information from partner agencies.

“This time, we had a big challenge. BC100_RS was entirely produced under a teleworking system”, explains Juliane Silveira, Geodesy and Cartography manager of the Santa Catarina State Unit of IBGE. “In March 2020, we started emergency telework, due to the pandemic. As planned, we would have to start this work in April. In less than a month, we adapted the entire production process, which took place within the IBGE network, in a consolidated database, to a decentralized system, requiring redoubled effort from the team. This project broke IBGE’s cartographic production paradigms and the result is yet another product with the same mark of excellence”, he adds.

This digital base is in free format (Shape File, GeoPackage and PostGis database dump), for use in Geographic Information Systems, being compatible with free and free software, and can be accessed here and through the geoservice, via IBGE’s Interactive Geographic Platform.

“We see a great benefit for those who need information from regions that are furthest away from large urban centers”, comments Juliane, emphasizing that rural areas are the most benefited by this mapping, as they suffer from a “blackout” of data. “We try to minimize this problem by bringing the same information density to both urban and rural areas”, says the manager.

The modeling follows the current standard in the SIRGAS2000 reference system and the Technical Specifications for Structuring Vector Geospatial Data in version 3.0 (ET-EDGV 3.0), covering classes of 13 of the information categories provided: Economic Structure; Energy and Communications; Hydrography; Limits and Locations; Relief; Transport system; Transport/Airport System; Transport System / Pipelines; Transport/Railway System; Transport/Waterway System; Transport/Road System; Large Scale Topographic Mapping Base Classes; and Buildings.

The product also presents the list of geographic names in CSV format, to be viewed in a GIS environment, where it is possible to locate, through their geographic coordinates, all the geographic names that make up the database, represented by points. The names present in the lists are associated, in addition to their latitude and longitude, to the respective categories and classes of represented elements.

More detailed information about the cartographic base is available in the technical note that accompanies the product, available here. BC100_RS can also be accessed through the INDE Geoportal and its metadata can be found in the IBGE Metadata Catalog.

About us

• Kai Michael Poppe has extended his multi-purpose-bot to also inform the D-A-CH Telegram group when a new issue of weeklyOSM is published.
  • Kai invited other Telegram groups that are interested to make use of this service too, using a new bot.
  • We have created a spreadsheet in which we ask administrators to enter the Telegram group that they want to be served directly when a new weeklyOSM is published.

Mapping

• Managing imagery alignment has always been a problem; bdhurkett found a solution for Burnie (Tasmania) as suburb polygons are well aligned with fences and other property boundaries. They outline how they are incrementally adjusting OSM objects to match these alignments more consistently.
• SherbetS showed a setup for river mapping using a PlayStation controller and JOSM.
• SK53 continued his examination of how natural=heath is used in Wales with a detailed example of a small hilltop heathland which was previously unmapped.
• Voting is underway for the following proposals:
  • motorroad=yes > , to formalise a definition of motorroad for Japan, until Saturday 4 December.
  • ref:EU:bwid=*, to record the unique identifier of a bathing site, until Monday 6 December.

Community

• Canadian cartographers discussed, on the forum, the relevance of special mapping for flood disasters and landslides in various areas of British Columbia.
• The Local Chapters and Communities Working Group presented the ‘OpenStreetMap Welcome Tool’. The tool is designed to make it easy to welcome new mappers to your country or region.

OpenStreetMap Foundation

• On the OSMF mailing list Heikki Vesanto suggested a ‘made with OSM logo’ along the lines of those of Natural Earth and QGIS. Note that this is subtly different from an OSM mark, an idea which was recently revived (as we reported earlier), in that it would be additional to, not a replacement for, existing attribution requirements.
• Michal Migurski, candidate for the OSMF Board, asked on MetaFilter about ‘organisations that form in spite of their grassroots counterparts’, and asked how ‘new members’ could ‘circumvent a community organisation to form something larger and more organised’.

Events

• Both State of the Map Africa and the HOT Summit occurred last weekend (20 and 22 November), a little too late for inclusion of highlights in this week’s weeklyOSM. One talk several people noted on Twitter, was by Alazar Tekle from AddisMap, one of the earliest OpenStreetMap startups anywhere in the world. No videos, at present, but you can view their, virtual, presentation at State of the Map 2010 on YouTube.

Education

• Pascal Neis left a message on the changeset of a Chinese newcomer to ask why they deleted lots of data. Another user in the comments pointed out that this was OSM mapping homework assigned to students by an instructor at Central South University. Other mappers from China also showed their disappointment > with these homework changesets. Should teachers be responsible for such improper behaviour of students? How should we deal with the teacher’s assignment of editing in OSM as homework?
• Videos of presentations by Heidelberg Institute for Geoinformation Technology (HeiGIT), given at the recent FOSS4G conference, are now available online. Subjects include: an OSM Confidence Index developed using the ohsome.org framework, and an introduction and update on MapSwipe .

OSM research

• Alexander Zipf’s group has received funding to start a new project related to climate change actions – ‘GeCO – Generating high-resolution CO2 maps by Machine Learning-based geodata fusion and atmospheric transport modelling’.

Maps

• Here are some selected OpenStreetMap-based maps from the penultimate week of the #30DayMapChallenge, which we have been following all month:
  • Day 17: Land: Steven Kay produced a rotating globe with only the largest islands visible.
  • Day 18 : Water: P*C chose an area of Florida with extensive waterways.
  • Day 19: Islands: Ross Island, Antarctica (Andrew Tyrell) and the islands of Abu Dhabi (leeolney3).
  • Day 20 : Movement: colourful isochrones of cycle times around Dumfries (D&G Placenames).
  • Day 21 : Elevation: Tbilisi (Lika Zhvania).
  • Day 22: Boundaries: Arctic boundaries with a polar projection (Andrew Zolnai), and a tiny pene-enclave on the Norway-Sweden border (Steven Kay).

Software

• The website Visionscarto announced > the launch of three tools built with OpenStreetMap and uMap to identify available agricultural lands and their uses by the association ‘Terre de liens’.
• Hauke Stieler created a web application called OSM Open to find POIs that are open at a selected point in time. The data can also be filtered by tags and the source code is available on GitHub. He has chosen to hide the OpenStreetMap attribution by default.

Did you know …

• … the existence of the xmas:feature key? While scarcely used (about 2000 items) and mainly in Germany, this ‘in use’ tag was introduced in 2009 and grows each year by a few hundred or so. Its use has been debated and a merging proposal with the temporary: namespace was made, but the proposal has been inactive since 2016.
• [1] … the Open Indoor Viewer called ‘OpenLevelUp‘?
• … there is a list of new keys recently created in OSM? Most of them involve typos or ignorance of established tagging principles. Comes with direct links to correct them.
• … OSM Streak, the gamified web application that encourages you to do small tasks in OpenStreetMap every day? There is also a Telegram account named @osm_streak_bot, which you can configure to remind you of your daily task.

OSM in the media

• The government of France has unveiled > its action plan for open source software and digital commons which, as its name suggests, aims to strengthen the use of open source and encourage the opening up of public data. A specific objective is to reference open source software and digital commons such as OpenStreetMap, a free and collaborative digital tool from which other tools such as transport.data.gouv.fr > are derived.

Other “geo” things

• Archival geodata are now available > as WMS layers from the Polish national geoportal.
• The general secretariat of the German Red Cross (GRC), based in Berlin, is looking for a ‘Manager Geoinformatics’. The position is responsible for the implementation of the project ‘Development of geoinformatics for the international humanitarian aid activities of the GRC – Strengthening the cooperation with the Heidelberg Institute for Geoinformation Technology’. The person chosen will also help develop programmes and basic approaches for the use and support of OpenStreetMap.
• Reibert wrote > about the official state register [uk] > of permits to harvest timber in Ukraine.
• SkyNews reported that Mapbox’s route to a stock market listing, through a Softbank SPAC (Special Purpose Acquisition Company), has run out of steam.

Note:
If you like to see your event here, please put it into the OSM calendar. Only data which is there, will appear in weeklyOSM.

This weeklyOSM was produced by Lejun, Nordpfeil, PierZen, RCarlow, SK53, Strubbl, TheSwavu, YoViajo, conradoos, derFred.

I would like to take this opportunity to thank openstreetmap Africa for organinising this year`s state of the map Africa. Before I go further, let me introduce myself here https://mapuganda.org/morish.html.

During this three day conference, I learned allot. The interesting session for me was mappathon where I was able to contribute to the openstreetmap through mapping and I learned new advanced josm tricks which makes mapping easier.

Networking during the conference was amazing. connecting to fellow mappers around Africa was something unforgetable to me. though time was not enough.

The lession that I learned from the conference will help me to improve my mapping skills and I will apply some of the ideas that I got from SOTMA to my community for development purpose.

My challage during SOTMA was lack of enough data which made me not to attend all the sessions but I am hoping to watch them on youtube once they are uploaded. The amazing session was the least but not last one which was SOTMA after party where I learned new dance steps from enock, shamillah, geoffrey and sharon who was outstanding and thank to Dj Angela. The session was full of jokes and I believe it was a session with the highest number of chats.

Many thanks to all the 75 speakers and organisers for making SOTMA colorful.

Knowledge sharing has a great power to change our communities and perspectives we have on different issues that affect us day by day. The State of the Map Africa virtual conference was just what we needed Malawi and Africa at large. Sometimes we may have helpful knowledge and skills, but sharing is far more important.

During the conference, Christine Mhone showed us how the knowledge and skills in mapping is very important in health, environment and risk and disaster management. Considering the state of Malawi’s health care and out vulnerability to climate change related disasters, indeed mapping can help in relief, search and rescue as well as post disaster activities such as tracking household affected and relief items delivery, through among others monitoring conditions of roads in the affected areas.

Innovations are also more important and encouraged in mapping. I took inspiration from the developer of Maproitette. This is making a visible difference to the communities we live and the world at large and I’ve been inspired a lot during the conference.

There is a great need to make people aware of the impotence of mapping as well as knowledge sharing as vulnerability of one location affects us all in one way or another.

We all have different stories and reasons to do open street mapping and the talk by Willy Franck on how OSM changed his life, we all can learn a lot from his experience and this should help us make positive impacts in our communities.

The speech by Monica Nthiga on technological development and improvements within the OSM communities was insightful and learnt a lot from her.

A big thank you have to go the organisers and moderators, all participants and all who spoke during the conference. I have gained more knowledge through attending the conference and I am looking forward to more of the same in the near future. Thank you all.

In preparation for Online conferences, I have always preferred to reserve a particular space equipped enough to participate during the conference. I must say due to lectures and other academic calls, I didn’t prepare such an environment to attend this conference. In spite of all, I had quality time to join in at some scheduled talk sessions and networking sessions with participants from other parts of the world.

One of the talk sessions I learned most was a talk on “Community mapping to improve flood preparation in Nigeria” which was facilitated by Shamilah. The talk exposed the different most flooded areas affecting communities and it also presented a solution by using mapped buildings, roads, and water areas edits on Open Street Map. The facilitator also recommended other solutions that could solve the flooding problems.

During the event, I networked with Sabina Abuga, a Mapper from Ghana who just recently earned her first degree. We discussed the SOTM conference, shared our experience in contributing to OSM, and also exchanged contacts. At the Network break session, I also had a call with Becky Chandiru, who was one of the facilitators during the HOTOSM Data quality internship 2020. We made use of the period to connect well enough and shared some ideas with each other.

I really had a great time and insightful learning at the SOTM Conference
