1. adım: ArcGIS REST sunucusunda yanlış konfigürasyon nedeniyle erişilebilen WFS endpoint ini kopyalıyoruz.
2. adım: QGIS indirip kuruyoruz, ardından WFS endpoint i ilgili kısımdan ekliyoruz.
3. adım: Endpointten elde edilen altlıkları açıyoruz ve istediklerimizi Shapefile olarak dışa aktarıyoruz.
4. adım: Son olarak eğer projeksiyon EPSG:4326 değilse JOSMdeki OpenData eklentisi genelde düzgün açamamakta. Bunun için de [mygeodata.cloud/ şu siteden] GeoJSON haline dönüştürüyoruz.
5. Adım: Multipolygonlar düzgün aktarılmadığı için sınırları elle bir daha düzenleyip OSM sunucusuna yolluyoruz. Veride azıcık kayma olması mümkün. (muhtemelen veriler önce ED50/TUREF’den aktarılıyor, biz de bunu bir daha dönüştürdük. hata payı var)

Some days ago, I searched online for a bus route that was supposed to be newly introduced to go from Kilkenny to New Ross. I didn’t find it, but I found another one which pleased me even more which goes from Kilkenny to Fiddown (ref=891). The reason it pleases me is that the other route is already partly covered by another bus company and I don’t really need it, and the 891 covers a route that goes past several historical sites and at least two hiking routes. Since I don’t drive, I will certainly avail of it myself. I don’t mind organizing myself lifts, and I enjoy the company of my “drivers”, but sometimes it’s good to be more independent. For context, the bus route started on January 20th 2025.

Street-level imagery

So I decided to track it, because I don’t really trust Transport for Ireland’s route maps, and I can’t be sure that they didn’t use proprietary map material to provide the routes online, even though their background map is OSM. But I have seen routes on their website which they seemed to have taken out of thin air which had nothing to do with the actual route the bus takes.

From the bus schedule, I had a fair idea of where the bus was going to go, and I had travelled most of the roads already and captured street-level-imagery, but I thought it would be no harm to do it again. Of course, that is a bit tricky on the bus, and I couldn’t ask the driver to leave the GoPro Max on the roof of the bus. I had brought the magnetic foot, but turns out, there is very little plane metal space on the bus. So the setup was a bit wobbly, but it worked. It only swayed in the bendier bends. ♦

It’s partly held in place by my bag: ♦

I was sure it was gonna crash at some point, especially with some of the bumpier rural roads, but it didn’t.

This is the sequence where I had least coverage before.

The battery lasted just about long enough.

As usual, I uploaded to Mapillary first and then to Panoramax. I might have forgotten to change the viewpoint angle on the Mapillary imagery… At least on Panoramax, I could go in and change it later.

Drive-by mapping Speed limits and road ref numbers

A project I’m working on at the moment is adding maxspeed to the rural roads. On February 7th 2025, a directive from the Department for Transport lowered the speed limit on the “local rural roads” (the ones where the reference number starts with L and those without any reference number, I presume - I’m still waiting for a reply from the Department for Transport) from 80 km/h to 60km/h. If you’ve ever driven on one of those, you’ll wonder how anyone in their right state of mind would even attempt to go at 80 km/h, but that was the law. We’re (OSM) still missing a lot of the L numbers nationwide, because of course, the government is not able to provide them as open data, that would be too easy. So, that was one of the things I looked out for - missing L numbers. It would have saved me a lot of frustration, if they were displayed closer to the junction in OSMAnd, but I had to long-click on everyone of them where it wasn’t displayed to see whether it was already mapped or not. I also added notes for missing speed limit signs, even where they wrongly still displayed 80 km/h. I mapped those on the desktop PC without the wrong speed limit, just to know where the traffic signs are for later reference and to be able to split the highway at the correct location. I’m also not quite sure how to map speed limit signs which have different speed limits on the front and back, bc I can’t use direction then.

Bus stops

I used OSMAnd for tracking the routes, adding notes and adding the odd POI (post boxes, defibs, wayside shrine etc).

When I got on the bus, I asked the bus driver to point out where the new bus stops are, because I did not expect bus stop signs for most of them. #Ireland #experience He said I was right, because it was “a new bus route”. Sure, that makes sense. We wouldn’t want people to know where the bus stops are to promote the route and establish sustainable routines, would we?

Anyways, some locations are therefore also only estimates, because he didn’t slow down, and just told me the name of the place in passing. Someone will have to re-survey in about a year, when there is a slightly better chance of bus stop signs, but I have my doubts that they will ever come. As a Canadian friend put it, “oral tradition is still very strong in Ireland”.

The “highlight” of the trip was an unscheduled excursion into the bus depot, because the heating on the bus wasn’t working, and the gaggle of bus drivers (four at some point on the bus) thought it would help to add water somewhere. It didn’t. So, four hours at about 8°C. The sacrifices we make for the general good. But the bus depot is mapped now which one would not locate from the street.

Here’s the route, if anyone is interested.

construction

I also spotted a couple newly built or under construction houses for which I also left notes. Most of them are not visible on the outdated aerial imagery yet, so I drew estimates and left fixmes.

Addresses

I think I spotted one house number and three house names which I added to the map. Because, unlike in other countries like Lithuania or the Netherlands, the government also doesn’t publish open address data. Do I sound frustrated? That’s because I am.

I think in total, I left 7 pages of notes: Notes by b-unicycling.

All in all, I’m glad to report that I was not the only passenger on the bus; there was a bus driver in training and for most of the journey, there were one to four other people with me. The word has spread already, it seems.

I've upgraded toolforge:wdlocator to PHP 8.2 and Symfony 7, and in doing so I think have fixed a long-standing (but unknown to me!) bug with how it was selecting the user interface language. It's supposed to change based on the Accept-Language header, but there was a bug with that in our ToolforgeBundle. I think we fixed that bug ages ago, but I forgot to update wdlocator. So now I have, and it can be read in Indonesian at e.g. wdlocator.toolforge.org/?uselang=id#map=17/-8.72520/115.17650

(I mention Indonesian, and the map above is centred on Denpasar, because that's where I'm going tomorrow. For the Wikisource Conference.)

I know I should also add a UI for actually selecting a language, but that'll have to wait.

Well, I’ve just discovered that anybody can edit like it’s wikipedia. So instead of doing homework, I’ve spent several hours fixing little things in my hometown. This is fun.

[out:xml][timeout:25];
// fetch area “Kildare” to search in
{{geocodeArea:County Kildare}}->.searchArea;
// gather results
(way["highway"="tertiary"]["maxspeed"="80"](area.searchArea);
way["highway"="unclassified"]["maxspeed"="80"](area.searchArea);)->.roads;

// print results
(.roads;>;); out meta;

I used this query in overpass turbo:

[out:xml][timeout:25];
// fetch area “Kildare” to search in
{{geocodeArea:County Kildare}}->.searchArea;
// gather results
(way["highway"="tertiary"]["maxspeed"="80"](area.searchArea);
way["highway"="unclassified"]["maxspeed"="80"](area.searchArea);)->.roads;

// print results
(.roads;>;); out meta;

and loaded it directly into Josm, then replaced 80 with 60, and added maxspeed:type=IE:rural as suggested on the talk-ie list, which I hope will make the difference between “rural” local roads, and those at the edge of urban areas, obvious.

I couldn’t find any exceptions listed by Kildare County Council, so I’m reasonably confident I shouldn’t have scooped up any inappropriately, but do shout if I’m wrong.

Mapping

• Requests for comments have been made on this proposal:
  • traffic_sign:id=* to explicitly reference official traffic sign identifiers, improving data accuracy and interoperability with external databases.
• The proposal to add golf=out_of_bounds, for mapping the area designated as being outside the boundaries of a golf hole, is open for voting until Saturday 22 February.

Mapping campaigns

• Mapbox has thrown down the gauntlet to the German mapping community, claiming that there are roads in Germany that are yet to be mapped. The contributors wish them luck and hope that Brian Sperlongano has popped enough corn for all of us.
• In response to recent disruptions in the US Federal Government disruption of foreign assistance, HOT is launching a 90 day campaign of ‘Open Maps for Humanitarian Needs’, inviting volunteers to map.
• YouthMappers at Universitas Pendidikan Indonesia is set to host ♦ a mapping party in Bandung, aiming to document and identify local plant species.

Community

• Just van den Broecke was interviewed by OpenCage regarding the OpenStreetMap Alpumapa Workshop.
• jbcharron shared ♦►♦ a series of Overpass queries aimed at improving associatedStreet, a relation used to link streets with houses for addressing purposes.
• Gregory Marler has made a video detailing his experience of mapping Perth, Scotland, using EveryDoor and KeypadMapper.
• Amanda McCann and Milvus emerged as joint winners in OpenCage’s January 2025 edition of #fridaygeotrivia. This month’s challenge asked participants to name country pairs sharing a land border of less than 50 km in total length.

OpenStreetMap Foundation

• The OpenStreetMap Foundation has announced that eight new entities, including ESRI, Meta, Microsoft, Niantic, and QGIS, joined its Corporate Membership Programme in 2024, contributing at various levels to support OSM’s infrastructure and community efforts.

Events

• IVIDES.org® has opened the pre-registration for the Green Open Data Day 2025 event, to be held on March 31, 2025, in Rio de Janeiro (Brazil), as part of the initiatives celebrating open data around the world. You can consult the program and register today. In-person and remote activities are planned to map trees with OpenStreetMap and to remind people of the importance of vegetation cover in the face of the current climate crisis.
• Open Knowledge Brasil is looking for proposals suggesting open data events, including those associated with OpenStreetMap, to celebrate Open Data Day 2025. Ideas are needed by Monday 17 February.

OSM research

• Héctor Ochoa-Ortiz and Barbara Re, from the Università degli Studi di Camerino (Italy), have explored why and how commercial organisations contribute to OpenStreetMap, identifying five key ways: data editing, tool development, event sponsorship, OSM-related funding, and community building. These approaches are motivated by both business needs (for example, improving data quality) and social values (fostering community engagement). The paper also addresses challenges such as governance barriers and technical limitations that have led to alternative initiatives such as Overture Maps.
• Niroshan and Carswell have published a paper with an analysis of machine learning approaches, focusing on their application to updating OpenStreetMap.
• McKeen and others have published an article about the evolution of humanitarian mapping within the OpenStreetMap community, in the Scientific Reports. The authors concentrated on the editing of buildings and roads in specific countries. The analysis of temporal patterns revealed the impact of major disaster activations for the 2013 Typhoon Haiyan, 2014 West Africa Ebola Crisis, 2015 Nepal Earthquake, and 2017 Mexico Earthquake – as well as Hurricanes Irma and Maria around the same time. Subsequent disaster activations showed less engagement from the OSM community except during the COVID-19 pandemic period. Outside of crisis times, the trend-cycle analysis revealed that humanitarian mapping experienced sustained growth regarding monthly added buildings and highways from 2012 to mid-2017. However, the trend-cycle analysis further depicted a consolidation phase since mid-2017.

Maps

• [1] -karlos- (aka DerKarlos) has revived his old 3D-rendered OpenStreetMap project ‘OSM go’ by integrating Panoramax images after Mapillary’s API shutdown, and is now exploring other improvements, including better 3D rendering techniques and possibly rewriting the project in Rust or Zig. You can view the Brandenburg Gate, one of Germany’s most famous landmarks. There is an ‘OSM go’ project page on the OSM wiki and at GitLab.
• After several months of research and server-intensive mapping, Charlie Plett has completed the British Empire’s territorial boundaries in OpenHistoricalMap.

OSM in action

• OK Klima ♦►♦ has created ♦ a map that shows the current situation (mobility, energy, consumption, buildings, food system) of the municipalities in Switzerland in relation to the Paris climate agreement. OpenStreetMap data was used as the basis for calculating ♦►♦ some of the indicators.

Programming

• Sarah Hoffmann has been selected for the one-year pilot of the Sovereign Tech Fellowship programme by the Sovereign Tech Agency. The fellowship will provide support for the maintenance of Nominatim, Photon, osm2pgsql, and pyosmium throughout the next year. Congratulations Sarah!
• Matthias Schwindt, from GPS Radler, explained ♦►♦ how to install and use alternative OpenStreetMap maps on the Garmin Fenix 8 watch, covering different installation methods, map activation and usability, as well as insights into Garmin’s Outdoor Maps+ subscription service.

• Version 1.6.0 of the Panoramax Android app Baba has been released. This version brings GNSS support for phones without Google services, better notifications for picture uploads, and allows saving to external storage.
• GeoCompas.AI has introduced the SAMGEO-API, a service designed to streamline geospatial AI Data generation using the SAM2 module, which promises to enhance workflows for mapping projects with tools like DS-Annotate and the JOSM Magic Wand plugin. OSM contributors have talked about their user experiences on the OSM Community forum.

Did you know that …

• … the geocompx project is a community-driven effort to provide resources for learning and teaching geocomputation in multiple programming languages? Geocomputation with R and Geocomputation with Python are available as open source books, with Geocomputation with Julia in development. The making maps section of the books describe various cartographic packages. The interactive maps are based on Leaflet and OpenStreetMap.

OSM in the media

• Eleven Landesamt für Geoinformation und Landesvermessung Niedersachsen (Hannover Germany) trainees have supported ♦►♦ the Missing Maps project by mapping 1387 buildings in OpenStreetMap to aid humanitarian efforts. Guided by the German Red Cross, they focused on flood-prone areas near Montréal and other global regions, gaining valuable technical and social insights.Contributors from Québec were a bit surprised to read of this emergency call on the HOT Tasking Manager. Pierre Béland tooted suggesting that next time they might concentrate on climate change in Europe.

This is cross-linked from my blog, posted on 11 July 2023

I recently joined the Humanitarian OpenStreetMap Team in modering their Community Working Group and Tech Working Group’s discussions on AI-Assisted Mapping.

This, in part, was a reminder that I (still!) haven’t published an OSM diary that summarises my MA research, and that publication is still process. But it was also a reminder that I have yet to really summarise or bring together what I have shared so far.

Here’s a short summary:

Moderation: “Perspectives on AI-Assisted Mapping”

• Session 1: www.youtube.com/watch?v=JTtTh6gHEwI
• Session 2: www.youtube.com/watch?v=6pfdDV9xSoo
• These two sessions - recorded as hour-long discussions with unrecorded 30 minute discussions at the end, were really interesting (and much-needed!) community spaces for the OSM community. I’m grateful to have been given the trust needed to facilitate, and learned a lot from folks there. Most notably, I think the discussion primarily ended up focusing not on “what we should be building” but what AI means to mappers in the first place (these being very different things)!

Talk: “Crisis Maps, Community, and Corporations (an Anthropologist’s perspective)”

• Link: www.youtube.com/watch?v=_0a84F0pdNU&t=351s
• Slides: Coming soon!
• This was given at the Humanitarian OpenStreetMap Summit in 2021 in the form of a talk. It shared some of my initial thoughts around crisis mapping specifically, and citations in that direction. In particular, I focused a bit more on what defines the kinds of crises that become maps, and informational asymmetries within the community.

Talk: “Mapping crises, communities and capitalism on OpenStreetMap: situating humanitarian mapping in the (open source) mapping supply chain”

• Link: www.youtube.com/watch?v=kqkdY-NG0LI&t=636s
• Slides: zenodo.org/record/7004452
• This talk was given at the State of the Map conference (the global summit for the OSM community) in 2022 in the science/research track. I shared a summary of my MA research, with many more ethnographic excerpts than I was able to bring to the previous iteration. In this talk, I focused primarily on asking the kinds of questions that emerged from my conversations, discussions, and observations over the last ~2 years. Folks’ reactions were so kind!

Thank yous

• Thank you for the invitation to moderate Arnalie Vicario and Petya Kangalova for the invitation to join the Community Working Group
• Thank you to the Science track at the State of the Summit for accepting my talk proposal, and for the supportive folks who asked questions at the conference and encouraged this work

Imagery Offset Database

Todo mapeador aficionado debería saber que todas las imágenes obtenidas de forma remota (por ejemplo, imágenes satelitales y fotografías aéreas) y otras fuentes, excepto las trazas GPS, suelen estar mal alineadas con respecto a la realidad. Como resultado, el cartógrafo debería poder alinear las imágenes en su editor preferido utilizando trazas GPS. El proceso lleva entre 5 y 10 minutos y, debido a la precisión del GPS, los resultados varían. No es tan malo si eres el único cartógrafo en cientos de kilómetros a lo largo de cientos de años, pero para la cartografía cooperativa, incluso una variación de un metro importa.

Un análisis del problema reveló dos posibles soluciones, ambas igualmente efectivas. La base de datos de desplazamientos y el complemento de desplazamientos implementan ambas; no se excluyen, sino que se complementan entre sí, lo que permite al mapeador verificar los desplazamientos no solo con trazas GPS, sino utilizando un método de alineación alternativo.

Cada objeto en la base de datos OSM tiene coordenadas (en grados en la proyección WGS84/EPSG:4326), una fecha de creación, un autor y una descripción, que ayudan a determinar la aplicabilidad y la cobertura de un desplazamiento.

Es una buena práctica utilizar esta base de datos en nuestro mapeo de cada área. Si te interesa aprender a usar este mecanismo puedes leer: wiki.openstreetmap.org/wiki/ES:Imagery_Offset_Database
