Sorry for the late notice.

As a friend and I were adding the 57th tag to a climbing gym in Belgium, I wondered what the element with the highest tag count is. I couldn’t find such stats (which may be a good thing), so I downloaded belgium-latest.osm.pbf from Geofabrik and wrote a simple Python script that uses Pyosmium to do some counting for me.

Without further ado: the Belgian record for highest tag count is… the relation for Belgium itself actually, which currently has 491 tags. The non-relation with the highest tag count is, boringly, the node for Belgium, with 288 tags. Next up are Brussels (156 tags), the Council of the European Union (79 tags), one particular section of the River Meuse that somehow got its name mapped in 57 different languages (65 tags) and the Irish embassy (also 65 tags). Next up is the first element that has a lot of tags not because it’s just flooded with languages! This maritime beacon north of Antwerp in the River Scheldt has a respectable 63 tags to describe all its lights. Our climbing gym is not far off from this one, and has a lot more diverse information in its tags I’d say.

I noticed that the relation for Belgium also has a high version number, it’s at its 1043th revision. That prompted me to take a look at version numbers too. But 1043 isn’t even close to our record, which goes to the superroute relation for the E40 (version 3141). Granted, that’s international. The version record for a purely Belgian object is the hiking route GR 126 (version 1103) from Brussels to Membre-sur-Semois. Just like with tag counts, I find it more interesting to look at non-relations here, though. There the honour for highest version goes to one of the outer rings of a farmland multipolygon south of Mons, which is at version 277. Funnily enough, in contrast with its senior version number, it almost has no tags to speak of, only a source!

And should I even say… If you’re now inclined to go add tags or bump versions just for the sake of it, don’t. If I ever do a follow up on these stats and see that you’ve done this anyway, I will flat out ignore your object in future reports (yes!) and generally be very cross with you.

Lougouma round

Some of the most often seen pages on taginfo are the pages describing a key. To be more specific, the “Overview” tab on that page. And it has never really looked that great. The layout is strange and a lot of prime screen real estate is wasted.

And to make matters worse, the layout totally breaks on small screens:

So it was high time we did something about it. The new design is built around fixed size boxes containing different information about that key, as you can see here:

The boxes will wrap as needed, so the whole thing is still reasonably pretty on small screens:

To fit the values distribution chart into a box, it had to change. It uses a 3D layout now which shows a lot more information. I threw in a small version of the chronology chart and instead of just showing the image from the wiki, a list of wiki pages is shown that link directly to those pages. So there is a lot more information right there on the overview page.

Oh, and all of this goes for the tag pages and the relation type pages, too. They have also been updated with the new layout.

An added benefit of those boxes is that we can have more or less of them as needed. For instance when there is no wiki page about a key, the wiki box will not show up. For some tags (like website or wikidata) an extra box will be shown with links. I am already thinking about more boxes to add, but this will come at another time.

The new layout is now online, try it out at taginfo.openstreetmap.org.

I created this for my own use, but am sharing it here because it might be useful to other people too. This is the style and there’s a brief readme.

It uses different colours to highlight different map layers. It’s not supposed to look nice; just to show you what is there.

I believe that everything described in the schema is included. If a feature does not appear it might be because:

• it’s not in the Shortbread schema.
• it’s in the schema, but is for some reason missing from the OSMF vector tiles.
• it’s in the tiles, but there’s a bug in this style.

There are lots of features in the first category, and there seem to be a couple in the second. If anyone finds anything in the third category please let me know!

Últimas contribuciones

¡Ya la vereda Cascajo Abajo se encuentra totalmente mapeada!

He tardado un montón de días mapeando esta vereda, en parte porque hubo semanas en las que no cointribuí al mapa, y porque es una vereda considerablemente grande.

Consideraciones

He estado pensando en la posibilidad de usar DAMN para seguir con el proyecto de mapeo de Marinilla. Aunque la infraestructura del Tasking Manager de HOT es muy conveniente, y la Comunidad OSM Colombia ha sido lo suficientemente amable conmigo como para dejarme alojar este proyecto en el grupo de Colombia, considero que sería apropiado migrar a una alternativa “individual” de mapeo organizado. Aún no estoy muy familiarizado con la herramienta, y valdría la pena empezar a hacer pruebas. Por el momento, la próxima vereda (La Esperanza) se va a montar en los próximos días en el Tasking Manager. Espero que para la vereda número 4 o 5 ya pueda migrar a DAMN, si lo considero viable.

Sostenibilidad

Creo que el proyecto, tal como se ha venido desarrollando, es un poco insostenible. Uno de los elementos principales de OSM es la posibilidad de trabajar en comunidad. Por ahora, esto ha sido un esfuerzo primordialmente individual, y no me gustaría que se mantenga así por mucho tiempo. Por varias razones: * No es humanamente posible (por lo menos en un tiempo razonable) mapear todo el municipio por mi cuenta. * Me gustaría poder convocar a la comunidad de Marinilla y de otras partes del país para que ayuden a tener mapas urbanos y rurales consolidados.

He pensado en la posibilidad de hablar de OSM en las instituciones educativas de Marinilla, y así poder ganar contribuidores de la región. También he considerado la posibilidad de agregar un poco más de información a las veredas que ya han sido mapeadas y hacer un trabajo con las Juntas de Acción Comunal para que tengan acceso al mapa y que, por medio de esta experiencia (en caso de que sea favorable), se pueda replicar en otras veredas y darle impulso al proyecto, bien sea incluyendo más personas que mapeen o que se generen algunos incentivos para continuar con más intensidad. Por el momento, será un trabajo lento, pero constante.

Siguiente paso

Antes de seguir con La Esperanza, me tomaré un tiempo para incluir todas las Sedes Educativas en zona urbana y en zona rural. Demarcando tanto los puntos como los terrenos que hacen parte de la sede.

Como lo dije anteriormente, la siguiente vereda es La Esperanza.

Espero que la próxima actualización no tarde mucho en llegar.

¡A mapear!

Una crónica inspirada en la hazaña del Dr. Diego Rosselli y la potencia de OpenStreetMap

En las entrañas de la geografía colombiana, donde los mapas a menudo se revelan como bosquejos incompletos, este médico neurólogo emprendió una odisea sin precedentes. El Dr. Diego Rosselli, armado con su espíritu aventurero y sus dos Land Rover (El tinieblo y el caricare), se propuso recorrer cada municipio de Colombia. Durante 20 años, este incansable explorador recorrió 1.105 municipios, trazando una ruta que lo convirtió en el primero colombiano en lograrlo y convertirlo en un referente del turismo y la geografía nacional.

Lo que hace aún más fascinante esta travesía es la herramienta que el Dr. Rosselli utilizó para orientar su viaje en varias oportunidades, OpenStreetMap (OSM). Este proyecto de mapeo colaborativo, permite a cualquier persona crear, editar y consultar mapas digitales, que se convirtió en el copiloto invaluable del médico en su recorrido por los caminos menos transitados de Colombia.

OpenStreetMap: Más que un mapa, un compañero de viaje

A diferencia de los mapas convencionales, OSM ofrece una flexibilidad y precisión incomparables. El Dr. Rosselli pudo encontrar vías carreteables y trochas que no estaban registradas en otros visores web, lo que le permitió acceder a lugares remotos y descubrir la riqueza cultural y natural de Colombia.

“Openstreetmap casi siempre supera a otros servicios”, afirma el Dr. Rosselli. Gracias a esta herramienta, logro encontrar rutas alternativas, evitar peligros y descubrir paisajes que nunca se imaginó.

La capacidad de OSM para ser actualizado en tiempo real por cualquier usuario fue fundamental. Al encontrar errores o información faltante en los mapas, los voluntarios pueden realizar las correcciones necesarias y compartirlas con la comunidad OSM. De esta manera, no solo se benefició de la información de otros, sino que también contribuyó a mejorar los mapas.

Un legado para Colombia y el mundo

La travesía del Dr. Rosselli es mucho más que una aventura personal. Al documentar su viaje en su libro Pueblos y ciudades de Colombia y compartir sus recorridos a traves de X e Instagram , está dejando un legado invaluable para Colombia y para el mundo. Sus recorridos detallados y precisos pueden llegar a ser una herramienta fundamental para el desarrollo de las regiones más remotas del país, facilitando el acceso a servicios básicos como salud, educación y transporte.

Además, la iniciativa del Dr. Rosselli ha inspirado a otros exploradores y amantes de la geografía, en su última charla Explorando la Colombia inaccesible Este aventurero narra con detalles el viaje a los 42 municipios que no tienen conexión terrestre con el país.

El futuro de la cartografía colaborativa

La historia del Dr. Rosselli y OpenStreetMap demuestra el poder de la colaboración y la tecnología para transformar nuestra comprensión del mundo. Al permitir que cualquier persona contribuya a la creación de mapas, OSM está democratizando la cartografía y empoderando a las comunidades locales.

En un futuro cercano, es probable que veamos cada vez más iniciativas como la del Dr. Rosselli, en las que exploradores, científicos y ciudadanos comunes trabajen juntos para crear mapas más detallados y precisos de nuestro planeta. Estos mapas no solo serán útiles para la navegación y la planificación de viajes, sino que también serán fundamentales para abordar desafíos globales como el cambio climático y la conservación de la biodiversidad.

La odisea del Dr. Diego Rosselli es un recordatorio de que la exploración y la cartografía no son actividades del pasado, sino que siguen siendo relevantes y necesarias en nuestro mundo cada vez más conectado. Gracias a herramientas como OpenStreetMap, estamos descubriendo nuevos horizontes y construyendo un futuro más sostenible para todos.

Severe floods and landslides devastated Sukabumi Regency, West Java, after two days of intense rainfall, with over 100 mm of rain falling in a short period, according to the Meteorology, Climatology, and Geophysics Agency (BMKG). On Wednesday, December 4, the overflow of the Cikaso and Cibening Rivers inundated numerous areas, displacing residents and severing access roads. The hardest-hit areas included Palabuhanratu, Sagaranten, and Pabuaran. Floodwaters reached heights of 80–90 cm, submerging homes and halting transportation.

In Sagaranten, neighborhoods like Kampung Rangcabungur faced dramatic rescue operations as narrow alleys flooded waist-deep. Rescue teams, battling strong currents, evacuated several infants and their mothers. “We successfully rescued two to three babies. It was a tense process, but thankfully, everyone was saved,” said the Head of the Sukabumi Police’s Samapta Unit.

Flooding impacted at least 27 villages across 20 districts, with seven districts, including Ciemas and Gegerbitung, reporting widespread inundation. Landslides struck 14 locations, particularly in Simpenan, Warungkiara, and Palabuhanratu, while soil movements were reported in Cikembar and Bantargadung. The collapse of a 12-meter-long bridge on the Loji-Puncak Darma road added to the region’s challenges.

In Kampung Parungseah, Desa Curugluhur, and neighboring areas, the Cikaso River’s overflow swept away vehicles and flooded dozens of homes. Officials from the Sukabumi Regional Disaster Management Agency (BPBD) identified six districts as flood zones and seven districts as landslide hotspots.

Emergency response teams, including 61 personnel from the National Police’s SAR unit, were deployed to assist in rescue and recovery efforts. Local authorities have begun repairing infrastructure and monitoring weather conditions as heavy rains continue to threaten the region.

Upon learning about this news, I used OSM_PANTAU! to explore the humanitarian mapping activities by the Indonesian community in the affected region.

The circles are color-coded to indicate the recency of activity: red represents more recent updates, while blue indicates older ones.

Captura de pantalla de XMAS-Map mostrando las atracciones navideñas de Málaga en 2023, basado en datos de OpenStreetMap. Créditos: Colaboradores de OpenStreetMap y XMAS-Map.

El Ayuntamiento de Málaga está actualizando su página web con las actividades que se vienen desarrollando en el municipio con ocasión de las fiestas navideñas de 2024. También ha publicado ya la programación oficial de eventos (PDF 3.71 MB) y la guía de belenes (PDF 7.25 MB).

No tenía pensamiento este año de actualizar el mapa navideño de Málaga en OpenStreetMap, al menos no de la forma sistemática como lo hice el año pasado. No obstante, sí me gustaría animar a otros a colaborar en su actualización.

En la Navidad de 2022, se añadieron al mapa navideño de Málaga 9 belenes, 7 buzones de Reyes Magos, 3 alumbrados navideños, 2 mercadillos, 1 pista de patinaje sobre hielo y 1 árbol de Navidad. En la Navidad de 2023, se actualizaron los datos y se añadieron algunos objetos nuevos, logrando un mapa navideño de Málaga que mostraba 7 árboles de Navidad, 2 tiendas de artículos navideños, 12 belenes, 10 buzones de Reyes / Papá Noel, 4 eventos, 2 iluminaciones y 4 mercados navideños.

Toda la información necesaria sobre cómo mapear atracciones navideñas está disponible en el wiki de OSM. Los resultados de la actualización se podrán visualizar en el mapa navideño creado por Miche, en OpenStreetBrowser o en la aplicación móvil OsmAnd, seleccionando la categoría de Navidad.

¡Feliz Navidad!

P. D. (2024-12-08): La propuesta de mapear atracciones navideñas de Málaga apareció en el número 750 del semanario de OSM.

Today, panning in Kampala, Uganda, I noticed so many place=village and place=neighbourhood , often the same name is duplicated.

MapSwipe on the Web Experience

Recently, I had the privilege of leading a MapSwipe training session for a corporate group, and it was an incredibly rewarding experience. While I’ve conducted online trainings before, this one felt particularly special. Despite my initial nerves, I was able to deliver a smooth and engaging training session.

Initially, I felt a bit nervous about taking on the role, especially since I was filling in for a colleague. “Corporate” to me also sounded really scary and extremely formal. However, with a bit of preparation and the support of a wonderful colleague, Nicole, I gained the confidence to deliver a successful training session. I focused on guiding participants through the web version of MapSwipe, a tool close to my heart.

To prepare for the training, I immersed myself in the web version of MapSwipe every single day for 2 weeks, leveraging the support of a helpful colleague. I also selected a relevant project for the training, focusing on water scarcity in Gokwe, to demonstrate the practical applications of the tool. The exact project I planned to use got completed only 5 days after putting it up! I was confused, but then decided I could still expand the AOI in the same region because of the prolonged droughts. This worked perfectly fine, and I got to use a project that I had not only put up but also that I am working on with the Africa Matters Initiative.

I logged in at least 10 minutes before the start of the training session, tested my computer and setup. The host started the meeting; we said hello and 5 minutes past the hour we started. Honestly it took me only 8 minutes to go through the slides and thereafter went on to the live demo of the web app. This is where I took my time, went very slowly, communicating with my audience as I had a smaller group of people on the call. I let them follow through with signing up and to make the training interactive, I encouraged participants to work alongside me on the live project. This hands-on approach helped them grasp the concepts quickly and effectively. We discussed building identification techniques, data validation, and the importance of community engagement. The debates made the room come alive and got them to pay extra attention. I loved the interaction and how they found the whole idea really cool.

When I had 10 minutes left, I then moved to showing the community stats, downloading the data and shared a bit about the HOT Tasking Manager. I really enjoyed this experience and I am still head over heels about it, so much so that after filling in my colleague I rushed to text my mentor Sam about my experience with the group. Sam is the wonderful being who introduced me to MapSwipe and Nicole is the best buddy who puts me in the spotlight. I call Sam my GIS muscle as his inbox is loaded with my GIS support requests. Nicole is the morning sun who is always illuminating my strength to the world.

The MapSwipe community continues to amaze me with its kindness and support. I’m grateful for the opportunity to connect with such talented and passionate individuals. Through their guidance and encouragement, I’ve been able to grow as a mapper and contribute to meaningful projects while impacting the communities around me at the same time.

Such experiences continue to reinforce my belief in the power of collaboration and the importance of sharing knowledge. I’m excited to continue learning and contributing to the open mapping community and supporting others on their mapping journeys.

Backround

About 6 years ago now, the Ireland OSM community had a bunch of online and face-to-face discussions. There was a desire to have a common campaign, rather than everyone just paddling their own canoe, mapping old boundaries, addding 110KV monster pylons, plotting the holy stones of Clonrickert, or whatever you are having yourself.

Why Buildings?

And so #osmIRL_buildings was born. It took lots of months to pull together. There was a discussion document put out, and lots of decisions and guidance via videos, long conversations on Telegram, and frequent issues discussed on the mailing lists. The task was designed with a few things in mind. Firstly, the community recognized that compared to other territories, we had relatively small levels of completion of buildings. Secondly, a prominent academic had stated that the Irish Government knew more about the number and condition of cattle than it did about buildings. Thirdly, a lot of citizen science projects were trying to collate and capture where derelict and disused buildings were located in cities, with the hope that they might be repurposed for housing. Fourthly, there was a National Planning Framework launched in 2018 that concluded that the spaces for the next 1 million people to live in could not be sprawl outside of Ireland’s cities and towns. There were other reasons too, but those are the ones I recall, so apologies to all those other reasons and their proponents. Nevertheless, all of the ones I mention here could have been addressed by the creation of a fully open spatial dataset of the buildings on the island, and not what passes for open data by data.gov.ie.

Reservations

Of course there were detractors; some mappers worried about the threat of being inundated by the glibness of millions of “building”=”yes” objects. One man in Kilkenny was worried that the climate would have changed by the time the task would finish. He might yet be right.

Kick Off

The #osmIRL_buildings campaign began with gusto and with a small number of regular contributors, county-level tasks on a task manager. What we aimed to do was make a base-map, in other words a very foundational level map, with correct building shapes and all buildings attempted. We had lots of good banter we got going and mapped several counties, Kilkenny, Sligo and Carlow being first across the line.

My Break

Four years into it I stopped making regular contributions, but egged everyone else on and promised to come back. And I kept my promise this year initially hittting StreetComplete, and leveraging the fresh new buildings and completing quests and adding addresses out on the ground. However, that led me to realise that the basic mapping wasn’t very accurate. That ranged from wrong guesses at terraces, to whole buildings being missing and lots of buildings left with the “yes” and “house” tags.

Current Offerings in the tasks

So this drew me back to JOSM, where I started to see the horror of the full picture. This included tasks mapped where existing buildings left by earlier mappers were left “as-is”. Where mappers added objects without trying to offset (so you are left with 2+ offsets in a small area). Although the tasks were very specific about “attempt all buildings” and “provide the correct shape” that’s miles away from what is now being done.

How it was meant to be

I won’t speculate here about the drop in standards of what we are doing, but I will point out that long-range campaigns bear their own special risks, and if we had a time machine I would use it to ensure mappers gets breaks and avoid burnouts where the collective quality drops to this standard.

If you are a craft mapper we need your help in validating and mapping these tasks according to their instructions. Please help us come together and improve our mapping quality.

Had to write something about this. Well, the USA Geofabrik (Continental + HI and AK) extract is now well over 10GiB. And my poor Garmins still only can handle 4GiB gmapsupp.img files. Yeah, I have to lose over 6GiB of stuff now to get it to fit. I’m not sure how long this is tenable, but yes it’s a continuing struggle to get it to still work…
