First full pass-through of my hometown

About eight months ago I started mapping my hometown, and earlier today I reached a major milestone of having gone over everywhere boxed in by the Sabine River Diversion Canal and the CPKC railroad. I’ve gotten a lot more detailed and generally more accurate with mapping, so rather than moving on I’m going to do a (hopefully much quicker) second pass, particularly for where I did not yet start u

About eight months ago I started mapping my hometown, and earlier today I reached a major milestone of having gone over everywhere boxed in by the Sabine River Diversion Canal and the CPKC railroad. I’ve gotten a lot more detailed and generally more accurate with mapping, so rather than moving on I’m going to do a (hopefully much quicker) second pass, particularly for where I did not yet start using street-level imagery to verify road names, building/business names, and other micromapping targets I like to do (an embarrassing number of power poles and street lamps). I expect to have every road de-tigered and every visibly signed POI named sometime next year. From that point on I think I’ll focus on de-tigering the rest of the road network in the parish, then maybe start mapping other nearby towns.

Léarscáil 2025

As part of the Ireland chapter of OpenStreetMap a few years ago I set up a tileserver and a map frontend that defaulted to showing placenames in the Irish language (Gaeilge). Recently I spent some time improving both these services.

As part of the Ireland chapter of OpenStreetMap a few years ago I set up a tileserver and a map frontend that defaulted to showing placenames in the Irish language (Gaeilge). Recently I spent some time improving both these services.

Vector Tileserver

Previously the default style was named ‘ga’ and available at: https://tileserver.openstreetmap.ie/styles/ga However, last weekend I added a new ‘style’ named ‘sraid-v1’. You can take a look at it here: https://tileserver.openstreetmap.ie/styles/sraid-v1/ The screenshots below show a comparison. The new style is much brighter and has icons generated from Maki icons into a sprite sheet (see generate_sprites.py in the github repo). I also fixed a few things I didn’t like about the old ‘ga’ style.

If you are currently using tiles from tileserver.openstreetmap.ie and want to use the new ones, you will need to change the code where it currently points to: https://tileserver.openstreetmap.ie/styles/ga/ You can now use: https://tileserver.openstreetmap.ie/styles/sraid-v1/ So to use this vector tileset you might use something like the code below with MapLibreGL var map = new maplibregl.Map({ container: 'map', style: 'https://tileserver.openstreetmap.ie/styles/sraid-v1/style.json' + keyParam, hash: true, maxPitch: 85 }); The previous style ‘ga’ is still present so there should be no breaks in functionality if you choose to continue using the old style. The code is available here: https://github.com/jonnymccullagh/irish-language-osm-tiles

Léarscáil

I did a big upgrade for the service that displays the map from the tileserver: https://learscail.openstreetmap.ie This latest version uses React frontend with a node backend. The backend only proxies to the the external APIs that require an API key that I would not want to share publicly (Logainm, Graphhopper, geograph). The frontend does not require a login and there is no tracking. Any preferences saved are stored locally in the user’s browser (local storage). The code also contains a tauri wrapper that will allow builds of the app for Android, iOS, Mac, Linux or Windows but I will have to make a few amendments for the services that require an API key.

New Features: - New Style: It uses the new style mentioned above (sraid-v1). - Location Info: When clicking on place names you get an info panel which includes info from Logainm, Wikipedia and a photo from geograph.ie - if data exists. - Directions: There is also a feature to get directions between two places (uses Graphhopper at the moment but I may add support for https://project-osrm.org/) - Home: you can right-click to save a ‘home’ location - History: Stores the list of recently clicked locations - Favourites: - Right-click to create a favorite - Right-click to show/hide favorites - Export favorites to a .mappa file to send to others - Import favorites from a .mappa geojson file

The code is available here: https://github.com/jonnymccullagh/learscail

I am hoping to build a version that will work on Android phones but I will need to find some time to get back to that.


Good Afternoon

Dear OSM users,

I need to inform you that, unfortunately, the Toledo Province area is quite neglected and lacks detail. This isn’t anyone’s fault, obviously; it’s something that needs improvement, and together we can fix it. Furthermore, one of the most populated areas of Toledo, the La Sagra region and its surroundings, lacks updates and good features. We also cover the southern Madrid

Dear OSM users,

I need to inform you that, unfortunately, the Toledo Province area is quite neglected and lacks detail. This isn’t anyone’s fault, obviously; it’s something that needs improvement, and together we can fix it. Furthermore, one of the most populated areas of Toledo, the La Sagra region and its surroundings, lacks updates and good features. We also cover the southern Madrid area, which also lacks updates.

WE NEED PEOPLE WHO CARE ABOUT THIS AREA.

LET’S DO SOMETHING BIG.

Thanks for reading.

Veteran addicted once more

More recently I find myself addicted to OSM once more after a long hiatus. I guess working in the civil road design space has me interested in capturing features around the streets such as crossings, sidewalks, street furniture and recreation spaces.

I’m shocked by the number of sidewalks I have found that cross a street not as a crossing. I’m fixing these as I find them.

I’m shocked by the number of sidewalks I have found that cross a street not as a crossing. I’m fixing these as I find them.

My end goal is to try and resolve as many items from StreetComplete as I can around where I live and work, adding to the accuracy of the overall map model locally.

[1] ProjetDuMois update, now operating on a global scale © ProjetDuMois and OpenStreetMap Contributors.

Community

  • The 30 Day Map Challenge 2025 has officially begun, featuring 30 distinct mapping themes, one for each day of November. Participants are invited to create maps inspired by the daily themes and share their work on social media using the hashtag #30DayMapChallenge.
    • For the first day’s theme ‘Points’ Michaël has contributed a map highlighting the world’s mountains exceeding 8,000 metres in elevation, created using R and the Overpass API.
  • After having successfully acquiring the topographic maps of Namibia (we reported earlier), Grant Slater is now raising funds to purchase the historic 1:50,000 topographic map series of Eswatini (formerly Swaziland).

Events

  • Unique Mappers Network have live-streamed days two and three of the State of the Map Nigeria 2025 conference.

Education

  • TeachOSM has made a video tutorial demonstrating how to map OpenStreetMap features using satellite imagery. The tutorial guides viewers in identifying ground features by interpreting colour, shape, pattern, and texture.

OSM in action

  • Indonesia’s National Research and Innovation Agency, through the Indonesian Seagrass Mapping Partnership project, has developed Seagrass Connect, a mobile application that enables public participation in seagrass mapping (plants that compose the seagrass beds), by allowing users to take field photos and record seagrass cover conditions directly from their mobile devices. The application uses OpenStreetMap data as its base map.

Software

  • 1 François Lacombe gave an update on recent upgrades to ProjetDuMois (Project of the Month). This software now allows you to monitor OSM contributions for topic focused projects at a world scale, whereas the tool was initially designed for the country scale. François and Adrien Pavie have improved the workflow and interface to provide OpenStreetMap history digging functionalities for projects that started years ago, a significant development that was made possible thanks to Osmium and the MapYourGrid initiative. The update also gives hints about their roadmap and invited anyone interested to help in further development.
  • The October 2025 edition of the MapLibre Newsletter has been published.

Releases

  • Eugene Kizevich announced that OsmAnd version 5.2 has been released. This release introduced a new ‘Marine’ nautical map style, enhanced search result details, added new features for travellers and drivers, and added a cloud autosync system for user data.

OSM in the media

  • Markus Reuter, of Netzpolitik, reported that the Chaos Computer Club Hamburg has taken over the Surveillance under Surveillance project, a global map of video surveillance previously maintained by a single individual. The project, which uses OpenStreetMap data, provides accessible information on the locations, types, and viewing directions of surveillance cameras.

Other “geo” things

  • Alongside choosing the new mayor for New York city last Tuesday, voters also voted on several ballot proposals, including Ballot Proposal 5: Create a Digital City Map. This measure seeks to establish a centralised, digital version of the city’s official map under the Department of City Planning, consolidating various separately maintained paper maps into a single unified digital system. This proposal was approved by 73% of voters.

Having grown up in the Current River Area there are many same details I was able to add to the map such as small back roads that are mainly used my locals. Additionally one thing I noticed with is that many features where outdates. There where restaurants and stores that closed down years ago and new ones have since opened up in their place. So I updated the map to have the newest data. From using openstreetmap I learned a lot about citizen mapping and the people who live in an area know it the best to map it. But also using a mapping website open to the public comes with risks of inaccuracies. What I found to be challenging was that some houses weren’t properly lined up so it impacted when I tried to add a new house.

All of this might be truncated for length (it is here), but the most important information does appear.

O contorno ficará com uma aparência serrilhada, com ângulos de 90°.
O segundo passo é fazer uma suavização usando o plugin Scripting, com o código disponível aqui.

Geralmente, duas iterações são suficientes.

Contudo, dependendo do nível de zoom, pode ser adicionada uma grande quantidade de nós desnecessários.
Isso pode ser facilmente corrigido simplificando o caminho:
Ferramentas → Simplificar linha ou atalho Shift + Y.
A quantidade de nós é definida conforme a preferência do mapeador.

Também é possível economizar cliques densificando linhas que foram adicionadas de forma mais simples — geralmente antigas, criadas quando não havia boas imagens de satélite.

I am a new editor of OSM, and I thought I would explore the tools and update familiar areas for myself. I added and updated areas in Bronte Creek Provincial Park. The OSM tools made it really easy to add new areas, points of interest, add some walking trails and label everything with accurate details. The park was already mapped with buildings, trails, roads, parking lots and much more. A lot of what I found myself doing was adding newly labelled areas, ex. Cow Barn, Cow Pasture. I am very familiar with BCPP, and now anyone looking to go to the park can have a better idea of what is really there. OMS is very easy to navigate, and I enjoyed using this mapping software. Not only is it a great tool to add for other people to use, but it is also great to see what is really in your surroundings.


Breve storia triste sui CAP

Ivan ha pubblicato recentemente una mappa dei CAP fatta da koriander sul gruppo Telegram @OpenStreetMapItalia.

Saltava subito all’occhio che c’erano diversi errori nei dati sorgenti su OSM. Perciò ho iniziato a fare delle query con overpass turbo per trovarli.

La prima cosa che ho fatto è stata quella di fare una query per trovare valori del tag addr:postcode che iniziano con una lettera diversa rispetto all’area geografica in cui si trovano. Ad esempio, in Piemonte, i CAP iniziano tutti con “1”, a eccezione delle province di Novara e del Verbano-Cusio-Ossola.

Ho scoperto che alcuni indirizzi sono stati copiati dal web. Di per sé non è un problema, ma lo diventa se il mappatore non capisce che il POI che sta aggiornando non è quello recuperato su Google e quest’ultimo si trova invece a centinaia di chilometri di distanza. Ad esempio questo, questo e questo.

Poi ho fatto una query che restituisce i CAP sintatticamente errati, ovvero che non sono composti da 5 cifre.

Ho così trovato che molti degli attracchi dei vaporetti a Venezia avevano un CAP (!!). La cosa più strana è che il valore era sempre “30121-30176”.

A guardare bene, però, questo fenomeno non era limitato a Venezia. Continuavo a trovare CAP in questo formato in tutto il Nord-Est e non capivo perché. Tra l’altro il tag “addr:postcode” era stato inserito anche nei posti più assurdi (fermate del vaporetto, monumenti ai caduti, ecc).

Poi ho avuto una illuminazione: il dato è stato copiato da Wikipedia senza alcuna verifica.

Dopo aver analizzato un po’ di changeset ho notato che TUTTI gli edit sono stati fatti con Organic Maps.

Ho quindi scoperto che Organic Maps compila automaticamente il CAP prendendo il dato da Nominatim, che a sua volta lo prende dal tag postal_code.

Tutti questi tag postal_code sono stati aggiunti dallo stesso utente nel 2023 (ovviamente copiandoli da Wikipedia).

Fine storia triste.


Starting with the cycling

I cycle around town a lot and I’d like people to join in. One of the barriers to entry is finding safe routes so I thought I’d try and update the map with the cycle infrastructure as it is built.

I was also pointed at StreetComplete so I’ll log more metadata in my area as I wander about.
