Th new release 1.7.1 fixes a few small bugs in osm2pgsql and closes some gaps in the geometry processing code released in 1.7.0. It also contains some security-related fixes as a result of the security audit.

• Added as_multipoint() function to complement as_multilinestring() and as_multipolygon().
• The functions as_multipoint(), as_multilinestring(), and as_multipolygon() will now always return single geometries if possible. Single geometries are always allowed where multi geometries are allowed, so this does’t break anything.
• The centroid() function now works for all geometry types.
• New length() function to compute the length of a geometry in map units.
• New reverse() function to turn geometries around (can be useful for ways tagged with oneway=-1).
• The simplify() function is now available for multilinestrings, too. (Not for polygons yet.)
• All example code in the flex-config directory has been updated for the new geometry handling capabilities.
• Create nicer error messages when trying to access a missing database extension, schema, or tablespace.
• Better checking of names (of tables, schemas, etc.) used in SQL in osm2pgsql and osm2pgsql-replication to avoid potentional SQL injection issues.
• Fix: Make sure relation members show up in the correct order in multi-geometries when using slim mode.
• Fix: Do not try to run ST_IsValid() on create_only columns.
• osm2pgsql-replication: The database parameter may be empty when connection parameters are supplied via environment variables.
• osm2pgsql-replication: when installed, now runs the osm2pgsql binary that was installed with it to avoid potential security issues through PATH manipulation.
• osm2pgsql-replication: Meaningful error when middle tables do not exist or the prefix is a bad one.

yesterday, while I was walking in the street before 8:00 PM, a soldier caught me and ask me why I put two phones in pocket. I replied to him its because one is not enough for my personal use. Again, He asked “why are you walking in this hour alone?” I couldn’t get a taxi I replied. “show me your residence ID”. I told him I don’t carry it around. I would lost it if I do that. Suddenly, He started searching me even in the inside of my pants but found nothing. I told him to let his hands off of me but he refused over and over again. Finally, he let me go because there is nothing he could do about it. As I started my walk again, his freind call me “hey you” coming from far. I turn around, What now! I said. He reached the man I was talking to and ask him the problem. After thinking for a while, he said “if I ever find you on other place we will have a problem but for now you can go”. I told him I am not going to go anywhere untill you prove my innocence now. He waited for a minute thinking what did I really do but couldn’t find answers. They left me where I was standing. Not very long, I got a taxi and I got home safely. If they didn’t held me I would have continue my walk because from where I stood Its only 3 km to my home.

Hi all,

Hacktoberfest is a yearly event where contributors get a T-shirt from hacktoberfest.com if they improve an Open Source Project.

MapComplete is open for such improvements. Head over to the repository. An ideal to get started is by creating a map layer about something that is interesting to you.

If you have questions on getting started, feel free to ask in our chat channel on matrix/element (telegram bridge )

Has anyone ever mapped an area because it was in some true crime podcast or video? I mapped the area (i.e. buildings) in Co. Cork in Ireland where the Sophie du Plantier murder took place while listening to a podcast about it.

And then Netflix went and made a documentary about it and used all that lovely OSM material without attribution.

Opera di presa

La diga di Barcis, detta anche del Cellina o Vecchia diga (1095179424) dopo la costruzione della diga di Ponte Antoi, è stata costruita all’inizio del 1900 per opera dell’allora appena costituita Società Promotrice per l’Utilizzazione delle forze Idrauliche del Torrente Cellina. La diga aveva lo scopo principale di funzionare come opera di presa per il canale di derivazione che percorrendo tutta la valle andava ad alimentare la centrale di Malnisio e successivamente quella di Giais e del Partidor. La diga, negli anni ‘50 ha cessato la sua funzione con la creazione dello sbarramento a Ponte Antoi di fronte all’abitato di Barcis.

Canale aduttore

Il canale aduttore, lungo circa 7 km, aveva la funzione di trasportare una parte delle acque del torrente Cellina verso la prima centrale idroelettrica di Malnisio. Il canale costruito all’interno della forra e parallelo alla Vecchia Strada del Cellina, si sviluppa in sponda destra a valle della diga fino alla località Monciaduda. Da qui il canale percorre una galleria prima di arrivare al bacino di calma dove è presente un imponente sfioratore a gradoni. Il canale termina nei pressi della centrale di Malnisio, dove dal bacino di carico partono quattro condotte forzate.

Ryan Lambert just announced the release of his book Mastering PostGIS and OpenStreetMap. It explains how to bring OpenStreetMap data into a PostgreSQL/PostGIS database (using osm2pgsql of course), cleaning it up in the process, and teaches you the ins and outs of data processing with PostGIS.

I was visiting my HDYC page today. I always get sentimental looking at my first changeset, a neat feature on HDYC. Here it is with ID 90313. This makes sense to me; I lived in that part of Amsterdam at the time and the timestamp coincides with the day I created my OSM account (while participating in a weekend-long mapping party).

But, when I scroll to the bottom of the changeset page info panel, I see there’s a previous changeset:

How is that possible? If I click on the previous changeset until there is no more previous changesets, I end up at this one, with ID 7671. But that changeset was opened and closed 10 months later, in April 2008.

I always assumed that changesets with a higher ID would also be newer, but that’s obviously not always true. My best guess is that the database got reshuffled in the early OSM API days. Perhaps coinciding with the disabling of anonymous edits in late 2007?

Mysterious. How will I be able to sleep now?

I really like the ‘notathon’ concept, so just posting a translated version of AngocA’s original diary entry (which was in Spanish).

On Saturday 1 October 2022, a notathon was held, as is customary one week after the Latam meeting. This time it took place in Mexico, and was coordinated by BigBlueButton - OSMVideo, where several people participated.

This time DAMN-project was used to divide the areas. For the division of areas we filtered by only the notes created from the Maps.me application. This is the task of DAMN: https://client.damn-project.org/?area=2407

We showed how to use the JOSM plugin, which automatically downloads the notes, and this allows to work in several areas, without having to leave the editor.

In total 63 notes were solved, with participants mainly from Mexico (alex_mayorga, Mapeadora, Sandra, among others), but there were also attendees from Venezuela (risturiz), Argentina (Manuel Retamozo) and Colombia (AngocA).

This activity has allowed us to work as a region, supporting each other, and each one contributing from their experience. We learned about tree mapping, humanitarian mapping strategies, among other things.

There were also very good questions, and we are going to create a couple of tickets in DAMN and OSM. For example: the OSM API should not create a note with the same coordinates on top of an existing, open one; instead, it should add a comment to the existing one.

If you want to see what happened at the Mexico Notathon, you can relive it at: https://youtu.be/oXmOmT8GT7Y

El sábado 1 de octubre de 2022, se realizó una notathon, como se acostumbra hacer una semana después de la junta Latam. En esta ocasión se hizo en México, y se coordinó por medio de BigBlueButton - OSMVideo, donde participaron varias personas.

En esta ocasión se uso DAMN-project para dividir las zonas. Para la división de áreas se filtró por solo las notas creadas a partir de la aplicación Maps.me. Esta es la tarea de DAMN: https://client.damn-project.org/?area=2407

Se enseñó cómo usar el plugin de JOSM, el cual baja automáticamente las notas, y esto permite trabajar en varias áreas, sin tener que salir del editor.

En total se resolvieron 63 notas, con participantes principalmente de México (alex_mayorga, Mapeadora, Sandra, entre otros), pero también hubo asistentes de Venezuela (risturiz), Argentina (Manuel Retamozo) y Colombia (AngocA).

Esta actividad ha permitido que trabajemos como región, apoyándonos mutuamente, y cada uno aportando desde su experiencia. Aprendimos de mapeo de árboles, de estrategias de mapeo humanitario, entre otras cosas.

Igualmente, hubo preguntas muy buenas, y vamos a crear un par de tiquetes en DAMN y OSM. Por ejemplo: el API de OSM no debería crear una nota con las misma coordenadas sobre una ya existente y abierta; en cambio, debería agregar un comentario a la existente.

Yesterday Russia annexed Ukraine, which is disgusting, but OSM is up to date, should I add the area annexed areas as part of Russia or not? I don’t want to put I want to keep OSM up to date.

After you’ve been out dancing 💃 & drinking 🍸 at the club🪩, that take away joint open at 2am 🌆 suddenly looks very appealing 🍔🍟🍕. So for every night club in OSM, I calculated the distance to the nearest fast food take away. Here’s a map of where you have to go >20km for a take away:

🗺️ explore this as a web map here

Here’s everything in Europe (blue = <1km, green=1→5km, yellow=5→20km orange=20→50km red=≥50km)

🔢 full raw data if you want to play with it yourself.

I used my new script, osm-distance-to-nearest with -a amenity=nightclub -b amenity=fast_food. Data is from end of Sept 2022. Data © OpenStreetMap contributors, and open data under ODbL

I wonder what’s going on Iberia (Spain & Portugal)? 🤔 It’s quite possible the simple OSM data model doesn’t match, and things aren’t tagged as fast food, or nightclub or they just do things differently. Ukraine & Eastern Europe also have low numbers. Many places in Africa have a large distance, but I think low OSM data coverage and I presume different mapping/cultural standards are a reason why. Do you have any thoughts? Leave a comment. I love this aspect of OpenStreetMap. I love being able to explore the world, and data, like this.

While exploring this, I found 2 night clubs far away from the nearest take away. They were in the middle of the desert (in SA & AU). Clearly mistakes, and someone fixed the map.

BTW, the absolute worst night club for a durty take away is Ибица, Anadyr, Far Eastern Federal District, Russia, which is 1,100km from the nearest fast food joint in Omsukchansky Urban District, Magadan Oblast, Far Eastern Federal District, Russia. Clubbing must be hard in Siberia. 🤣

Share this on social media: twitter 🐦 mastodon/fedi 🐘 (previous entry looked at gun shops & banks)

¹ “durty take away” is a semi-phonetic spelling of a Dublin Hiberno-English way to say it 😅 (I want to get better at actually _making maps)_

Motivations

Have you ever wondered when on earth, you would have opportunity to meet in person, have a handshake, a hug, an off-screen smile, take a coffee or even a lunch together with friends and colleagues you have remotely worked with, as weeks, months and years keeps counting in a virtual world of OpenStreetMap global community? Yes, our trending techs and AI keeps offering us the best of smart connectivity with everyone in a digital space of daily online activities that builds around us a world of virtual communities with uncertainties, barriers and boundaries of never meeting physically in our life time. Have you ever, thought about, the uncertainties of meeting in person such cool guy as Geoffery kateregga and the rest of HOT and OSM Africa local community leaders after consistently working virtually in HOT working groups, OSM Africa Mapathon, Community meeting and the rest for weeks, months and years in a virtual world of OSM.

What about meeting your boss-Pete Masters the Head HOT Global community (of course, if you are a community leader or aspiring and being mentored to be one) after having series of community mentorship, supervision, and virtual meetings through WhatsApp zoom, jitsi and the rest of the virtual platform that makes you forget the distance barrier and that you never had an opportunity to meet in person. Infact, after meeting virtually for years gone by, it only dawned on me that my very boss-Pete Masters had such an intimidating height that would dare me stretching out my neck when I first met him on my arrival for SOTM2022, in Florence, Italy. So, my virtual assumptions were wrong after all, thanks to FOSS4G2022 and unSummit HOT.

What about meeting with our dynamic CEO Tyler Radford at Humanitarian OpenStreetMap Team (HOT), the guy who has for the past 7 years pulled HOT through to the implementation of policies and strategies we push to him and the staff as HOT-Voting members. If you are in academics, and as a researcher, which would you prefer most? attending a conference like FOSS4G2022 and SOTM2022 academic track session or even the lightening talk session to present your peer-reviewed research paper or talk in person where you meet one-one to network further or to present virtually from home? What about longing to meet and network with new professional partners and business partners.

What about meeting with Open Mapping NGO-founders like Janet Chapman of Crowd2Map Tanzania, Patricia Solis of Youth Mappers and the CEOs of the Giant Geospatial industry companies like GeoCAT, Mapillary Team, Maptile and the rest. I think beside meeting all these amazing people and organization, my topnotch motivation for this travel grant was to gain and share academic and professional experience for local community impact. And you can imagine without travel grant from FOSS4G and unSummit-HOT supported by sponsors, how would an OSM or Open-Source GIS enthusiast in academics in Nigeria, where, salaries were not paid for more than 7 months or a student in African country struggling to survive afford a conference travel cost of more than $3000 to break the barriers and boundaries of OSM virtual world.

Reminiscing-My trip to Florence-Italy.

Yes, it all started with a dream – I mean dream or motivations, with realistic action: at FOSS4G, I want to have my research work about OSM local and remote mappers presented in person and on the first announcement of the call around February/March for abstract, threw in my abstract submission. Next, I desired to meet in person my academic mentor and supervisor-Professor Maria Brovelli. Yes, I also wanted to volunteer at the conferences and taking advantage of both FOSS4G2022 and SOTM2022 happening at the same city of Florence, I knew, it would be a great time for me sharing experience that would give me a vantage position to bring home to my country-Nigeria hosting FOSS4G and SOTM. Besides, being there as a community leader in Nigeria would be a great motivation for sustainable OSM volunteering for the community. Amazingly, this dream came true, when on 11th May,2022, at about 11:00am WAT, a smile-provoking mail hit my box reading as follows: It is our pleasure to inform you that your FOSS4G Travel Grant application has been accepted!

Please confirm reception of this message by next Monday, May 16, 2022 and provide the following additional information needed to process your application by May 20, 2022: • A copy of your valid passport photo page • Tentative dates of arrival and departure The next day I jumped out traveling to our neighbouring state- Bayelsa from Port Harcourt, Rivers State Nigeria, to get my international passport renewed !! so I can submit on or before May 20th. The journey of getting a renewed passport is another story that eventually took more than 8 weeks (due to unavailability of passport booklet) and finally on July 16th, I was able to proceed with visa applications using my renewed passport. And while this process was going on, June 20th, it turned out a double blessing as this mail also hit my box at about 2:38pm WAT:

Dear Victor N. Sunday,

Congratulations! We are pleased to offer you a travel support grant to attend SOTM and FOSS4G 2022. As you specified in your application, the travel support grant covers the amount required for a SOTM conference ticket, accommodation, and minimal costs not covered by the FOSS4G grant.

We are excited to have you join the conferences and share your ideas and experiences with the other participants. Your travel support grant is contingent upon your attendance. If you can no longer attend, please let us know so we can offer your grant to another of the many people who applied.

Thanks to the FOSS4G Travel Grant committee, the unSummit Scholarship committee, the visa committee, Picolo, Anisa, Dana and Arnalie for an amazing follow up. Infact, Arnalie was probably 24/7 online communicating and following up with visa and travel readiness and I can still remember, it was time to leave, she created a WhatsApp group unSummit Scholars 2022 for to ensure everyone was on course and had a hitch-free trip. Thanks to our big sponsors GeoCAT and the rest listed on sponsorship page of FOSS4G2022 and SOTM2022. And more, especially, thanks to HOT for coming up with the unSummit HOT Scholars World Tour program

Concluding to be continued if you need more!!

Though, I still have much stories to share about my pre-departure preparations (internal travels for visa processing, COVID-19 PCR-Test, missing my flight-not deliberately), my 8hours layover time in Germany Frankfurt International Airport, my time in Italy (SOTM participation, Archi Ross Hostel time, Volunteering FOSS4G participation and business networking) as well as my post-arrival experience that worth sharing. I look forward to continuing this diary with time on my side but for now, let the video and pictures speak. And remember, am not yet done with my breaking the barriers of OSM virtual world and so I still have more reasons to be granted to travel to FOSS4G and SOTM conferences ahead in other countries with the support of our sponsors. And, if you also need to be granted the fund to travel, then, let us not just dream, but also prepare and work to have more than enough and excellent reasons/motivations and score points to convince the committee that we need to break the barrier-using FOSS4G and or SOTM Travel grants. Keep the passion for volunteering in your local osm community, let’s do more academic research about OSM Science and open-Source GIS, join your local OSM community working groups, HOT working group and keep contributing to OSM. I need you to be the next travel grantee for FOSS4G and or SOTM. Thanks to HOT unSummit Scholars World Tour program.

Столкнулся с такой проблемой при редактировании дорожек во дворах жилых кварталов. Если из каталога объектов выбрать просто “пешеходная дорожка”, то после сохранения изменений на карте эта дорожка обозначается как “тротуар” (хотя тротуар как я понимаю это разновидность дорожки как правило прилегающая к проезжей части и с твердым покрытием). Внутри дворов никаких проезжих частей нет и соответственно тротуаров тоже быть не может. Я нашел временный выход, выбирая из каталога значение “тропа”. Но тропа в моем понимании - это специфическая лесная/парковая дорожка, а не внутриквартальная. Буду благодарен за помощь в этой теме

Abstractly speaking, every bit of information on OpenStreetMap, no matter how minute it may seem, enhances the user experience. Together, we can make OpenStreetMap better every day!

Hi folks,

I’m documenting my quest to add all the bike racks in Chicago to OSM. So far I’ve added about 200+ bike racks in the Lakeview area + the Loop. It’s been pretty easy to do so far, you just go out and walk around a bit then add points for all the bike racks. Always looking for folks to help out!

หลวงพี่รูปหนึ่งนั่งสมาธิอยู่ริมน้ำ ได้ยินเสียงดิ้นรนในน้ำก็ลืมตาขึ้น เห็นแมงป่องตกอยู่ในน้ำ. ท่านก็ใช้มือช้อนมันขึ้นมา ขณะเดียวกันแมงป่องก็ชูหางขึ้นแล้วต่อยไปที่มือท่าน ท่านปล่อยแมงป่องลงที่ฝั่ง แล้วหลับตาทำสมาธิต่อ.

ผ่านไปสักครู่ก็ได้ยินเสียงดิ้นรนในน้ำอีก ท่านลืมตาขึ้น เห็นแมงป่องตกลงไปในน้ำอีก ก็เอามือช้อนมันขึ้นมาอีก แน่นอนแมงป่องก็ต่อยไปที่มือท่านอีก ท่านก็หลับตาทำสมาธิต่อ

ผ่านไปสักครู่ เหตุการณ์ก็ได้เกิดขึ้นซ้ำอีก

หลวงตาที่อยู่ข้างๆก็พูดขึ้น “ท่านไม่รู้หรือว่าแมงป่องมันต่อยคน?”

หลวงพี่ตอบว่า “รู้ โดนมันต่อยสามครั้งแล้ว”

หลวงตาพูดว่า “แล้วท่านทำไมยังจะช่วยมันอีก”

หลวงพี่ตอบว่า “การต่อยคนเป็นสัญชาตญาณของมัน. แต่ความเมตตาเป็นสัญชาตญาณของเรา. สัญชาตญาณของมันไม่สามารถมาเปลี่ยนสัญชาตญาณของเรา”

ขณะนั้นเองก็ได้ยินเสียงดิ้นรนในน้ำอีก แมงป่องตัวเดิมนั่นแหละ

หลวงพี่ไม่รีรอ เตรียมที่จะนำมือที่บวมเป่ง ยื่นไปช่วยมัน

ขณะเดียวกัน หลวงตาก็ยื่นกิ่งไม้ให้กับหลวงพี่. ท่านก็นำกิ่งไม้ช้อนแมงป่องขึ้นมา

หลวงตายิ้มและพูดว่า

“ความเมตตานั้นดี ในเมื่อมีความเมตตาต่อแมงป่องก็ต้องมีความเมตตาต่อตัวเองด้วย ฉะนั้นความเมตตาต้องมีวิธีการของความเมตตา ต้องดูแลตัวเองให้ดี ถึงจะมีสิทธิไปช่วยผู้อื่น”

เรื่องนี้ทำให้ได้คิดถึงประโยคหนึ่งที่ผู้คนชอบพูดกันในปัจจุบันนี้ว่า “เดี๋ยวนี้จะทำตัวเป็นคนดีนั้นยาก”

ใช่แล้ว สัญชาตญาณของคนดีคือทำความดี. แต่ผู้ถูกช่วยอาจจะไม่ใช่คนดี และผลของการช่วยคนก็อาจจะไม่เกิดผลที่ดี. แล้วทำไมจึงเป็นเช่นนี้?

เหมือนกับที่หลวงตาพูดไว้ “เมตตาต้องมีวิธีการของความเมตตา”. “ความเมตตานั้นดี ในเมื่อจะเมตตาต่อแมงป่องก็ต้องเมตตาต่อตัวเองด้วย”

ความเป็นจริงเตือนเราว่า ต้องรู้จักรับผิดชอบต่อตัวเองก่อน ถึงจะสามารถรับผิดชอบต่อผู้อื่นได้อย่างแท้จริง. คนที่ไม่สามารถรับผิดชอบต่อตัวเอง แล้วจะไปรับผิดชอบต่อผู้อื่น จะเป็นไปได้ไหม? ต้องดูแลตัวเองให้ดีก่อน ถึงจะมีสิทธิ์ไปดูแลผู้อื่น

และประโยคนี้ก็ชอบมาก “สัญชาตญาณของแมงป่องนั้นต่อยคน แต่สัญชาตญาณของเราคือความเมตตา สัญชาตญาณของมันจะไม่สามรถมาเปลี่ยนสัญชาตญาณของเรา”

“ความเมตตานั้นดี ในเมื่อจะเมตตาต่อแมงป่องก็ต้องเมตตาต่อตัวเองด้วย และต้องมีวิธีการของความเมตตาด้วย”

จะไม่ให้ความเลวของผู้อื่นมามีอิทธิพลกับความดีของเรา จะไม่ยอมให้การกระทำและวาจาของผู้อื่นมามีผลต่อจิตใจและการกระทำของเรา

ผู้ที่มีปัญญาสามารถควบคุมอารมณ์ของตัวเองได้. แต่ผู้โง่เขลาเบาปัญญานั้น อารมณ์ของตนจะขึ้นอยู่กับพฤติกรรมและวาจาของผู้อื่น

“จงอย่าทอดที้งความดีของเราเพราะความเลวของผู้อื่น”

Updated aerial images have been added to the MapTiler Cloud and Data services this year, covering entire countries such as Italy, Spain, Portugal, and New Zealand in pixel resolutions up to 4cm! The imagery can be as recent as 2021 for parts of New Zealand and Spain.

The Czech Republic has also had updates to the south of the country, meaning that Brno is now covered at 10cm per pixel. Belgium, Slovakia, and Estonia were also updated relatively recently, with resolutions up to 10cm and dates as recent as 2021.

To find out how current and detailed our imagery is, see the table on this page.

We’ve selected a few highlights from the aerial maps here:
