What an event.

The local community prepared a really nice venue with a surprising Guest as entertainment as well as really tasty snacks. Well done.

I should have asked on the first day so now it’s just some thinking: Was there no way of getting better ventilation into the rooms at the university? But as I said, it’s now too late and I won’t linger on that any more.

More thoughts are still to come.

After a few “shakedown cruises” with the Max2 I began collecting imagery in earnest in August, and learned a few lessons.

1. Massive 10Gb files overwhelm older MicroSD-to-USB card readers. I struggled to copy the .360 files from the SD card to my desktop computer’s SSD drive, and resorted to Disk Drill (sometimes worked) and Roadkill’s Unstoppable Copier (sometimes worked) to copy them when copy, xcopy, and the Windows copy utility failed. I asked GoPro if it could identify the problem. When GoPro asked if I had tried a different card reader, I blew $7 on a new one rated USB-2 and it worked without problem. Issue solved, and something learned–just because a piece of hardware worked flawlessly for a decade doesn’t mean it will work today with the larger file sizes inherent to 360-degree imagery.

2. The battery lasts about 2 hours or less and a 64Gb SD card fills up in about 2 hours. Letting the camera battery die while filming is a headache, because the file isn’t closed properly. This is where Disk Drill came in handy to repair it so it could be copied and uploaded to Mapillary. A similar issue appears if you run out of storage. I blew $99 on a 256Gb SD card to avoid running out of space and put my wife in charge of monitoring battery life on the Quik smart phone app. Her reward for this is lunch at restaurants we have discovered while collecting imagery.

3. The Max2 can be toggled between collection at 5.6K and 8K resolution. I have experimented with both. Mapillary recommends 5.6K video at 30 frames per second but I have found that this makes reading house numbers difficult to impossible, and signage of businesses becomes very iffy. When experimenting with 8K resolution, I found both house numbers and signage become clearer and thus readable for addition to the OSM database. The tradeoff is file size, which quickly becomes an argument for a larger SD card (the Max2 can accommodate up to 1 Tb if you are willing to spend the money).

We have found a marvelous antique shop (even though we don’t need any more furniture), a fabulous Uyghur/Uzbek restaurant, and a shoe repair shop we didn’t know existed.

Salut

Une belle personne m’a parlée de QuackOSM quand je lui faisais part de la difficulté d’installer un serveur Overpass-API pour faire des requêtes en locales sans charger les serveurs communautaires.

Alors j’ai essayé … Et ça déchire de simplicité. 🤩

📢 ATTENTION: la doc est explicite : relations must be of type boundary or multipolygon. Il y d’autres contraintes, ce sera donc à voir selon les besoins …

Comme QuackOSM est un module Python et que je m’y perd tout le temps j’ai utilisé uv. QuackOSM se charge du téléchargement des fichiers PBF par exemple sur GeoFabrik OpenStreetMap Data Extracts.

Il suffit donc d’une seule ligne :

uvx --from 'quackosm[cli]' quackosm \
 --osm-extract-query France \
 --osm-extract-source geofabrik \
 --working-directory ./ \
--ignore-cache \
--cpu-limit 8

Ou si vous avez déjà le fichier “france-latest.osm.pbf”

uvx --from 'quackosm[cli]' quackosm france-latest.osm.pbf \
 --ignore-cache \
 --cpu-limit 8

Pour obtenir le fichier “geofabrik_europe_france_nofilter_noclip_compact_sorted.parquet” (9 Go) au format GeoParquet.

À noter:

• l’extra quackosm[cli] pour éviter “ModuleNotFoundError: No module named ‘click’”
• Au premier appel, uv télécharge et résout les ~40 dépendances (duckdb, pyarrow, numpy, shapely, etc.) et les met en cache localement

En suite on peut utiliser DuckDB pour faire des requêtes sur des objets OSM.

Par exemple avec l’outil de bureau DBeaver on créer une connexion DuckDB (le driver est téléchargé automatiquement), on ouvre une console SQL sur la connexion et :

-- les points d'eau potable dans le périmètre de "Tours Métropole Val de Loire"

INSTALL spatial;
LOAD spatial;

-- Récupérer la géométrie de "Tours Métropole" (un POLYGON)
WITH tours_metropole AS (
    SELECT geometry
    FROM geofabrik_europe_france_nofilter_noclip_compact_sorted
    WHERE tags['boundary'] = 'local_authority'
      AND tags['name'] = 'Tours Métropole Val de Loire'
    LIMIT 1
)

-- Récupérer les points d'eau potable (POINTS) dans cette géométrie
SELECT
    feature_id,
    tags['name'] AS name,
    ST_X(geometry) AS longitude,
    ST_Y(geometry) AS latitude
FROM geofabrik_europe_france_nofilter_noclip_compact_sorted
WHERE
    -- Filtre sur les points d'eau potable (amenity=drinking_water)
    tags['amenity'] = 'drinking_water'
    -- et que la géométrie est un POINT
    AND ST_GeometryType(geometry) = 'POINT'
    -- et que le point est dans la géométrie de "Tours Métropole"
    AND ST_Within(
        geometry,
        (SELECT geometry FROM tours_metropole)
    );

-- Et 3.7 secondes plus tard :

|feature_id|name|longitude|latitude|
|----------|----|---------|--------|
|node/7285184855||0.5381852|47.3109468|

|node/3613483888||0.5489893|47.3489299|

Notes:

• le “FROM” est le nom du fichier GeoParquet sans l’extension

Et on peut utiliser tout plein d’autres connecteurs DuckDB pour l’utiliser dans son langage préféré.

J’adore ! Il est content Rosco. 🥳

Песок, вода и вид

Нормальный песок, без мусора. Вода тёплая, но после чистая только утром и в обед. Виднееться остров Тафос.

Транспорт и парковка

Утром всё пусто, нигде нет знаков “Парковка запрещена”, эвакуваторов нет, все паркуються нормально, ничего не заграждают, мотоциклисты не бояться стоять на тротуарах, все велосипедисты - местные. Остаёться вопрос - где автобусы и такси?

Инфраструктура

Есть открытый душ, кран для мития ног, небольшая унисекс раздевалка, рестораны. Гостинные везде. Главные проблемы:

• узкий выбор еды в ресторанах
• нет просто магазинов
• и самое главное - НЕТ ТУАЛЕТА, даже в кусты лучше не ходить

Развлечения

Есть небольшая спортплощадка (возможно при школе/клубе т.к. она ограждена), место для пляжного волейбола, типо велодорожка (больше походит на обычный тротуар). Типо проблема - не туристический район. Более реальная проблема - нет детской площадки, дети возможно будут сидеть в телефонах

Местные

В заведениях все работники могут разговаривать на английском, но не на болгарском/русском. Иногда слышно знакомую болгарскую речь. На одну грецкую машину здесь 1 болгарская/румынская/молдавская, западных европейцев мало. Людей даже вечером немного

Итог в двух словах

Неплохой пляж, стоит брать гостинницу на одну ночь, но маленьким детям может быть скучно.

According to my personal schedule, I was supposed to attend the Guadeloupe room at around 14:50, for a talk titled “State of Panoramax.”

But in reality, the opening speech was still continuing at least until 15:02, and I had to sign out at 15:16.

I managed to finally come back at around 15:56, but by that time, the Guadeloupe room was already empty.

I managed to access the “traces of discussion about the talk” that were still left behind in the Venueless chatbox.

Someone asked this question at 15:21: “Question for Panoramax: What’s your take on privacy. Even with blurring, by having people take photos across a wide time range, AI will be able to deduct when someone was at home, where certain cars were parked and so on, revealing lots of personal info. Is that a good thing that we want to support?”

I have known Panoramax for a long time.

While editing WeeklyOSM’s entries, I frequently received news about their releases and updates. I also happened to learn about updates regarding Baba, a mobile app for contributing to the Panoramax project, because of my activity with WeeklyOSM.

But recently, I finally installed Baba and uploaded photos to Panoramax for the first time, thanks to someone’s suggestion on c.osm.org. I documented the whole train of thought behind this decision in this Mastodon thread.

The real reason was my realization that photographs uploaded through StreetComplete’s note feature are temporary and are going to be deleted soon. I wanted something similar, but permanent. Someone on c.osm.org – I forget who and in which thread – suggested using Panoramax instead. I tried it, and it worked.

Even so, at first, I had quite a hard time finding the right Panoramax instance, because most of them are limited to specific geographic regions, and my country is not listed.

MapComplete’s Panoramax instance promises an “Anywhere you like” guarantee, but I didn’t know how to simply upload photos without picking the right MapComplete theme. I couldn’t find the theme I needed. I wanted to upload photos taken on a specific road.

osm-fr? “Pictures preferably in France but allowed for Worldwide test”. That “test” thing made me uneasy. Does it imply that everything will be cleared after the test is over?

After scrolling all the way down, I finally found an instance that suited my needs : panoramax-ulm.

“Worldwide. The picture can be sent from anywhere in the world. 67k++ pictures. 19 contributors. Last activity 1 minute ago.”

Cool.

So I configured my Baba app to send photos to the panoramax-ulm instance. I tried uploading two photos while specifying the coordinates and angle of each shot.

Success. Nice.

But when I tried to upload my third photo, Baba showed an error warning without specifying what the error actually was.

I assumed that maybe the panoramax-ulm instance was temporarily down.

So I waited for several hours and then tried uploading the photo again.

Nope. Still an error.

So I tried uploading it to a different Panoramax instance.

Nope. Still an error.

Frustrated, I uninstalled the Baba app.

And that’s the real origin story of why I wanted to attend this talk.

What is the “State of Panoramax” today?

But while preparing this article, I started thinking of a different solution to fix this mysterious “third photo error”: what if I uploaded it directly through the web interface instead of uploading it via Baba?

And it still returned an error.

But at least this time, it gave me a nice, informative error message.

It said that there was missing metadata in my third photo, specifically the “date taken” field.

Weird.

Even though my first and second photos worked normally, I wondered what had actually caused this problem. My phone?

So I modified the metadata directly, aligning the “date taken” field with the actual date the photo was taken, which was conveniently stored in the filename, actually.

Then I tried uploading it again.

Success.

Nice.

So, it was partly Baba’s fault. Instead of simply showing an error message without any explanation, it should show the actual reason why the operation couldn’t continue.

But at least now I know that I can simply upload photos directly through the web interface.

Case closed.

Alright, let’s get back to the afternoon of August 28.

At 15:56, I found the Guadeloupe room already empty. After reading all the traces of discussion in the Venueless chat room, at 15:58 I went to the La Réunion room.

But nothing was being streamed there.

I went to Martinique.

Another empty room.

I went to Corse.

No stream.

I went to “TV Set.”

There was a video message:

“Up next. Guadeloupe. Geodesk 11:15–11:35 (start in 15 minutes).”

Then there was this message broadcast on the Venueless platform:

“Session will resume at 11:15 Paris time!”

That’s 16:15 in my local time.

So I still had around 15 minutes to kill.

I decided to go to osmbc.openstreetmap.de to do my daily WeeklyOSM duty.

At 16.19, I went to the Martinique room to attend a talk titled “Sneaking in OSM data into a Big Old Company” by Tristram Gräbener and Céline Durupt.

It turns out that the “big old company” is SNCF Réseau, the state-owned national railway infrastructure manager in France.

In their talk, they introduced osrd.fr, “Open Source Railway Designer,” a free and open-source software that simulates the operation of a railway network.

They also discussed the current state of OSM railway data in terms of usability and data quality, ranging from good (tracks, speed limits, electrification, and gauge), to okay (signals), and… bad (?) (stations).

They explained their workflow for “working” with OSM data in the wild, only to discover that a certain OSM contributor had already done one of the hard part : “integrating” the OSM data into their own internal reference system, which had already been published as open data.

And then came the final cherry on top : how to slowly overcome the inertia of a big corporation and get it to start adopting “the OpenStreetMap way” (… by luring them with cake).

They also noticed that other SNCF entities in France are already using OSM, contributing to OSM, and even meeting with each other at SotM.

In the final slide, they shared their concluding remarks about working with OSM data in the context of a big old company.

The talk ended at 16.37, followed by a Q&A session that lasted until 16.50.

At 16.51, I joined the La Réunion room, where there was a community panel discussion titled “The Democratic Stakes of Mapmaking.”

The panel featured Ksenia Ermoshina, Christian Quest, Françoise Bahoken, and was moderated by Matthieu Chatry.

Well, I didn’t watch it in full because there was another talk I was interested in watching that was running in parallel. So I had to move back and forth between La Réunion and Guadeloupe, then back to La Réunion again, and so on and so forth. But here’s some gist of the discussion that I managed to catch.

During the panel discussion, Christian Quest, as the product owner of Panoramax, occasionally shared several anecdotes from building and maintaining the Panoramax project, especially some of the unexpected use cases that emerged from real users.

Ksenia Ermoshina explained several map-based civic movements that took place in Saint Petersburg.

Françoise Bahoken gave a presentation as well. Of all the slides, this one resonated with me the most… You can probably guess why.

I was literally at the edge of my seat when I saw the heading “A combat sport”. I thought it was going to be a deep dive into the intricacies of OpenStreetMap edit wars.

Turns out, it was about rigging elections and world domination.

“Whoever controls the maps controls the world. Indeed, maps are formidable instruments of power, whether for controlling a country or rigging an election. But are they not also formidable weapons for challenging the established order? Cartographers of all nations. Unite!”

At 16.51, I joined La Réunion, only to discover that there was a sound problem. So I switched to Guadeloupe.

In the Guadeloupe room, the speaker, Pieter Vander Vennet, was comparing the iD editor and JOSM based on “ease of use” versus “powerfulness.” His talk was titled “Perspectives on Editors.”

At 16.55, I went back to La Réunion. The sound problem had already been fixed, but the panel discussion had not started yet. They were still doing the introductions.

At 16.58, I went back to Guadeloupe. The speaker there was introducing himself as the main developer of MapComplete.

At 17.00, back to La Réunion.

At 17.15, back to Guadeloupe.

At 17.23, Pieter showed this slide, which I quite strongly agree with.

At first, I was simply an iD editor user.

Then someone persuaded me to try JOSM. Even though the initial learning curve was steep, JOSM eventually grew on me. After getting familiar with JOSM, I started switching between iD and JOSM depending on the use case. A simple, small POI addition? iD. A huge edit spanning a large area? JOSM.

Then recently, I stumbled upon the profile of a veteran OSM mapper and noticed that they endorsed StreetComplete as one of the best mobile editors for OSM. I tried the “EE” (Expert Edition) of StreetComplete, and I’ve been falling in love with this editor ever since.

At 17.28, the talk in Guadeloupe finally ended.

At 17.33, back to La Réunion.

At 17.40, back to Guadeloupe. This time, it was a different talk: “Update on Attribution Enforcement for Users of OpenStreetMap Servers.”

There, Mateusz Konieczny explained the grim consequences for app developers who fail to properly comply with OpenStreetMap’s licensing and attribution requirements: getting blocked from the OSM tile servers. Instead of displaying the map tiles, the app shows an error notice: “ACCESS BLOCKED. THIS APP IS BLOCKED FOR NOT ATTRIBUTING OPENSTREETMAP’S VOLUNTEER-RUN SERVERS”

Thanks to this direct enforcement action, several app developers stopped using OpenStreetMap altogether and switched to Google Maps instead.

And apparently, you can enlist yourself in the “hunting team” too, by finding strong evidence of a web app or mobile app that does not properly comply with OSM’s attribution requirements, then submitting your tip here.

At around 17.48, I had to sign out because of some IRL activities.

7:36 pm, I jumped into Guadeloupe to watch the talk titled “Emergency Services Using OpenStreetMap in Germany.”

David Ganske from the German Fire Protection Association (vfdb) explained how OpenStreetMap data supports the operation of emergency services, ranging from OSM basemaps in command-and-control systems to various OSM-related apps used by crews on their personal phones, as well as several OSM tags that help support the team’s operations, such as surface=*, lane_markings=*, cycleway:separation=*, entrance=*, and paths to entrances.

The talk ended at 8:13 pm, followed by a Q&A session that lasted until 8:17 pm.

At 8:18 pm, I switched to La Réunion. There was a talk that looked very interesting, titled “Publishing 14,000 Businesses to OpenStreetMap: How Community Feedback Reshaped Our Publisher.”

Based on the talk description, it seemed that there was this French startup, Digitaleo, that allows business owners and chain managers to update information about their stores simultaneously across several platforms, including Google Business Profile, Apple Business Connect, Bing Places, Facebook, and OpenStreetMap. Apparently, there had been some pushback from the OpenStreetMap France community regarding the OSM edits related to this startup. After some discussion, they fixed the process. “A single complaint is an opportunity to correct the system upstream so the same class of problem can’t repeat. That philosophy, more than any technical decision, is what I’d like other organised editors to take away,” they said.

Unfortunately, the talk was in French, and I can’t understand French. But at least I could copy and paste the discussion and questions from the chat into a translation app:

“Digitaleo seems to target chains. How can an independent store manage its presence on OSM?”

“Are you working on the project alone?”

“Can you share some details about the technical stack used in your contribution process?”

“Since you retrieve OSM data, how do you handle data licensing issues?”

“Over the course of a week or a month, for example, how much data do you estimate retrieving from OSM versus how much data Digitaleo contributes to OSM?”

“Have you considered open-sourcing your contribution stack (at least the OSM component) to receive direct contributions to your codebase from the OSM community?”

It seemed that the discussion was quite lively.

At 8:41 p.m., I switched to Guadeloupe to watch a talk titled “Do Maps Have a Future in OpenStreetMap?” by Christoph Hormann, one of the maintainers of the OSM-Carto project.

The talk ended at around 9:09 p.m. I immediately switched back to La Réunion. Over there, the talk titled “OSMPID: A Persistent ID Specification and an Object Identity Service” was still happening midway through, despite having started at around 8:40 p.m.

The discussion, both in person and in the chatroom, seemed very lively. SK53 shared a blog post related to the discussion about some oddities found in the OpenStreetMap history files. It was quite relevant to the topic of persistent OSM object IDs.

The talk finally ended at 9:25 pm. It was time for a coffee break.

At 9:43 p.m., I joined Guadeloupe to watch a talk titled “Client-Side Transport Maps on OpenStreetMap.org” by Andy Allan, a maintainer of the OpenStreetMap website.

The talk started at 9:48 p.m.

He shared his experience working with vector tiles to develop and deploy the vector-based “Transport Map” layer, which is now available on openstreetmap.org.

While working on the project, he noticed several differences between working with Mapnik, which powers the raster tiles, and MapLibre, which powers the vector tiles.

He discovered several hacks that could be used as workarounds to fix some of the “visual bugs” he encountered in MapLibre.

Here’s one of the demonstrated visual bugs, which makes the railroad line look quite messy.

However, in some specific cases, Mapnik still contains plenty of features that have not yet been implemented in MapLibre at all. This makes the quest to create beautiful map tiles, or at least ones as beautiful as the “gold standard” Mapnik-based raster tiles, considerably harder.

Another problem he discovered involved MapLibre’s .json stylesheet source code, which requires a lot of copy-pasting of repeated styles when designing a complex stylesheet.

To address this, he developed “glug”, a markup language designed to simplify stylesheet development in MapLibre. He admitted that some of the more recent features in glug were developed specifically to solve problems he encountered while creating the “Transport Maps” layer.

The talk ended at 10:09 p.m.

After the talk was over, I immediately switched to La Réunion, hoping to catch another talk titled “Mapterhorn Terrain and Imagery,” but it seemed I was too late. The talk in La Réunion had already ended as well.

So, at 10:15 p.m., I went back to Guadeloupe. The Q&A session from the previous talk was still going on until 10:17 p.m.

The next scheduled talk in the Guadeloupe room was titled “Sourdough and Layercake: Removing Technical Barriers to Using OSM Data for Cartography and Analysis” by Jake Low of OpenStreetMap America. The talk finally started at 10:20 p.m.

Muy bien planteado, se realiza con mucha facilidad y se puede encontrar muy rápido para el destino deseado, excelente opción

Whenever I run, I carry a GPX device to track my route. Over time, I’ve collected a large set of personal GPX traces. It made me realize that this personal dataset isn’t particularly valuable when I look at individual traces, but it can be made useful once I’ve collected multiple traces over the same city neighborhood. The problem is that I have no idea where OSM ways are missing. This sounds like a great use case for aggregated personal data, because you tend to run the same streets most of the time. The basic idea is very simple: split GPX files into smaller segments, cluster them, and check whether each cluster maps to a known path or street in OSM. Then create an OSM extract for the new paths, along with the original GPX files, so that edits in JOSM are faster. It works! The slow part is making the edits, but at least you are aware of where OSM is incomplete in your neighborhood. The source code is on GitHub

DO THE RIGHT THING AND RECEIVE GOOD IN RETURN: THE ETERNAL CYCLE OF CONSTRUCTION

First Moment - That was the question: to attend in-person the SotM 2026 Paris or to support groups in Africa?

Around the same time that the organizers of State of the Map 2026 were offering early-bird tickets for the OpenStreetMap global community event, I was approached by groups of mappers from Africa, asking my company to support (as a sponsor) the initiatives they were planning, focusing in mapping features that were important to them and their community, based on their local realities.

So, rather than spending our resources on a sponsorship for the SotM 2026 event and attending in person in Paris, we decided to support three groups of young mappers from african countries: Cameroon, Kenya, and Ghana.

FAÇA A COISA CERTA E RECEBA O BEM DE VOLTA: O ETERNO CICLO DA CONSTRUÇÃO

Momento 1 - Essa era a questão: participar presencialmente do SotM 2026 Paris ou apoiar grupos da África?

Na mesma época em que os organizadores do State of the Map 2026 estavam disponibilizando a compra antecipada de tickets para o evento global da comunidade OpenStreetMap, eu fui procurada por grupos de mapeadores da África, para que a minha empresa apoiasse (como patrocinadora) as iniciativas que estavam planejando para mapear feições importantes para eles, de acordo com suas realidades locais.

Assim, entre gastar nossos recursos com um patrocínio no evento SotM 2026 e estar presencialmente em Paris, decidimos apoiar três grupos de jovens mapeadores, em países africanos: Cameroun, Quênia e Gana.

On 29-30 August, I attended the State of the Map (SotM) conference, in particular the scientific part. It's been 15 years since the last time that I attended the SotM conference (last time 2011!), and it's an opportunity to fill in a knowledge gap that I developed over this period. Unlike other conference reports that … Continue reading State of the Map 2026 – OpenStreetMap conference →

Agregar Beit Ya’akov Salama

The first time I became aware of the very existence of the “State of the Map” event was, I think, around 2022.

At that time, it was held in Italy. I think I heard about it somewhere online. All I remember is the group photo of the participants (there were plenty of people there) and the beautiful, cool-looking SotM 2022 logo.

That year, I had just recently graduated, so I could get involved in the OpenStreetMap movement more intensely than I had in the years before (before that, I usually only actively mapped during college holiday seasons. Once the holiday was over, I didn’t map anymore). That’s why at that time I started interacting with the community more, and eventually learned about this “State of the Map” event.

Even though I still don’t remember exactly where I first received the news about the event.

At that time, my first reaction was, “I don’t think I’m able to commute farther than either Jakarta or Bandung.” So, back then, I thought, “I don’t think I’m able to visit Italy.”

Fast-forward to after 2022. I gave several technical and/or philosophical talks about OSM sporadically, mostly online. From a technical standpoint, I talked about things like “how to map,” “how to use this particular tool,” or “introducing a tool that I recently built.” From a philosophical standpoint, I talked about ideas and dreams about “how the OSM platform should evolve in the future,” “how we should organize the people in the OSM movement,” etc., etc.

I finally had a chance to attend an OSM-related meeting physically, rather than online, for the first time around 2025. In this case, it was still within the boundaries that I had defined back in 2022 (Jakarta), so I was able to go.

In the same year, 2025, the global SotM was held in Manila. Relative to the rest of the cities on Earth, Manila is quite close to where I live, but still, “I don’t think I’m able to commute farther than either Jakarta or Bandung.” So I passed on it again. But at least I sent my poster there, which became my first-ever contribution to SotM.

Also, in the same year, 2025, I became pretty involved in the day-to-day editing of WeeklyOSM. There, I saw plenty of news submissions about SotM events all over the world, not just the yearly global SotM, but also region-specific SotM events. There were so many of them, but I don’t think I ever saw one being held in Jakarta and/or Bandung. So there went my chance to participate.

Then, on 30 July 2026 at 8:24 pm, I received an email from HOT. I only read it later, around 31 July 2026 at 1:50 pm. They were offering 100 free online tickets (GBP 10.00, including 20% UK VAT). Without any hesitation, I quickly filled out the registration form.

I assumed that these 100 tickets would be given on a “first come, first served” basis. And considering how late I was checking my inbox (for the sake of my own mind, I had decided to turn off notifications, but I still regularly checked my email at a specific time every day), I was quite afraid that I was already way too late to the party.

The registration form was sent. And all I could do was wait. If I failed to get the ticket, then it was what it was.

Then, on 20 August 2026 at 6:12 am, I received an email from the SotM Working Group:

“Hello, a ticket for State of the Map 2026 has been ordered for you. You can view the details and status of your ticket here. Best regards, Your State of the Map 2026 team.”

Alright. Cool. This was going to be my first SotM ever in my whole life.

On that same day, I immediately read through the programme page thoroughly.

There were plenty of parallel sessions, so I needed to plan ahead and decide which room I should go to at a certain time. I picked the topics based on my personal interests, while prioritizing attending all the “lightning talks” (I didn’t know the exact topics of those talks, but well, surprise me. I hoped I would feel lucky enough to stumble upon some interesting talks there).

Sometimes there were two topics that I liked equally, but they were running in parallel at the same time. I still marked both of them, just in case. Maybe I’ll go to the other room once this session is over. Maybe I’ll switch back and forth between them. I don’t know. Let’s see how it goes.

And on the same day (20 August 2026), I published that plan in this OSM Diary.

While researching the programme, I also learned that there was a Telegram group for all SotM 2026 participants. I joined it.

Inside that group, apparently someone had also made “country-specific groups” for SotM 2026 participants. That gave me the idea to make a specific group for people who attended this event through HOT’s free-ticket programme. Maybe we could talk in depth about the talks being presented, or network with each other.

From 20 August to 28 August, it was about one week. So during that time, I basically did nothing except wait in excitement.

So let’s just skip the story ahead to 28 August, the first day.

Alright. Timezone issues.

In Paris, the event started in the morning at 9:30 am, followed by the morning coffee break (10:40–11:15), lunch break (13:00–14:30), afternoon coffee break (16:15–16:45), and finally the end of the day’s programme at around 17:55++.

If this schedule is overlaid onto my own personal schedule and timezone, the event starts at 14:30 and ends around midnight. The mandatory breaks that I need to take are around 15:00–15:30 and 18:00–19:30. And the plan that I drafted beforehand didn’t actually take this into consideration. So I just had to improvise along the way.

Not to mention that there might be other “unexpected circumstances IRL” where I might not be able to access my laptop and attend a talk.

On that day (28 August), I opened my laptop at around 14:00, 30 minutes before the actual event started.

There was quite a lot of activity in the SotM Telegram group, so to kill time during those 30 minutes, I read through the chat one message at a time.

I learned that people were using trains to reach Paris from Toulouse, Marseille, Düsseldorf, etc. Meanwhile, among the people who had already reached Paris, they were discussing the arrival train station (Paris Austerlitz), the hotels they were staying at (mostly in noisy, near the SotM venue), and the location of the pre-event social event (Ground Control, also near Austerlitz).

I identified all the place names that were mentioned in the Telegram group, then put the coordinates of each place into LocationPad as a quick personal pet project, just to kill time while waiting for the event.

From the Telegram group, I learned that Paris had been raining the night before the event, and that “there has been some disruption to the RER C due to trees falling.” I also learned that registration started at 8:15 Paris time.

I jumped onto the Venueless platform at 14:30 (my local time). The chat room on the Venueless platform is quite crowded with people introducing themselves. I noticed at least 21 people introducing themselves, from Scotland, London, Brazil, Bangladesh, Nepal, Madagascar, Nigeria, and Zambia. The event finally started at around 14:43.

I encountered some severe connection issues at this point, so I failed to watch it uninterrupted. I only managed to get glimpses of it at particular times before the video got stuck again. I guess my own unstable internet connection was to blame here.

Here are the glimpses that I managed to watch:

14:48: Notice about the Code of Conduct (https://2026.stateofthemap.org/codeofconduct/) and information about the venue (https://2026.sotm.org/venue).

14:48: “Group photo. Join us on Saturday at 14h20 at the main hall stairs for the traditional SotM group photo!”

14:49: Information about coffee breaks and lunches.

14:49: I took this screenshot.

14:50: “Social event, Saturday 29 @ 19:30.”

14:51: “Thank you to our sponsors!”

14:53: Opening speech from TomTom.

14:56: Opening speech from the Director of Mapping Factory at Michelin.

15:02: Opening speech from the Head of Geodata Paris.

At 3:00 pm, I had to take my own personal break, so unfortunately I had to sign off.

And apparently, I also had another urgent personal matter, so I had to travel outside for a bit at that time.

As a result, I was only able to rejoin the event at around 3:56 pm.

(To be continued in Part 2…)

why does OSM have diray entries? i guess i’ll try to find out

Mapping

• In early August, v7.1.0 of the iD tagging schema was released, bringing new features to iD, GoMap!!, EveryDoor, and other editors. It includes multiple new presets (for example, for rooftop solar thermal collectors and building=tent), marks some fields as openinghours-like, new values in fields such as cuisine, some region-specific tweaks, many better icons, fixes destination fields, and stops asking translators to translate the same phrase twice in many places, also better documentation, better repository structure, and many other improvements.

Community

• A poll by Mateusz Konieczny asks which improvements to iD presets are especially wanted.
• Sven Geggus discussed how to integrate data from Nomady, an Airbnb-like booking portal for small private campsites, into OpenStreetMap and OpenCampingMap.
• Rphyrin prepared for the State of the Map 2026, which took place in Paris and online from 28 to 30 August 2026.

OpenStreetMap Foundation

• The OpenStreetMap Foundation announced that Proton AG has been recognised as a Platinum Corporate Member, following two donations over the past two years, totalling around €70,000.

Local chapter news

• FOSSGIS tooted that the FOSSGIS Conference is seeking a host venue for 2028. Interested parties can submit applications to host FOSSGIS 2028 by email until 16 October 2026. They also welcome expressions of interest in hosting future events, such as FOSSGIS 2029 or FOSSGIS 2030.
• OpenStreetMap US announced that the OldInsuranceMaps project has joined YouthMappers, Yesterdays, and OpenHistoricalMap as an OSM US Charter Project.

Events

• ^[1] You can visit the page featuring the amazing posters which are being presented at State of the Map 2026.

OSM research

• Radim Štampach et al. have assessed the performance of the fAIr mapping environment (we reported earlier) compared with manual mapping in JOSM. They concluded that fAIr reduced the performance gap between novice and experienced contributors but introduced AI-related errors, while manual mapping in JOSM was faster and more accurate overall.

Maps

• Mobi Mapr built ► a visual dashboard to analyse the accessibility of ice cream parlours in Germany, using OpenStreetMap data.

OSM in action

• OK Lab Flensburg have developed ‘Open City Planner’, an interactive city planning GIS application for Flensburg’s city centre, powered by OpenStreetMap data.

Software

• The Prototype Fund is offering a new funding line aimed at young individual developers or small teams residing in Europe, focusing on open-source software infrastructure or data security.
• Stadia Maps explained their initiative around reworking their cartography from the ground up. There are some details about their recent overhaul of water name labeling.

Programming

• Yassa9 explained how to geolocate a photograph using OpenStreetMap data, geometry analysis, and CUDA GPU programming.

Did you know that …

• … the Valhalla router can route through pedestrian areas? OSRM has it too; after a pull request, which started in May 2025, was recently merged.
• …. r/Fahrrad invited the German cycling community on Reddit to improve the data quality of Komoot, Strava, and Bikerouter by contributing to OpenStreetMap through the StreetComplete app?
• … there’s a discussion on the OSM Wiki about mapping the Moon using the same principles as OpenStreetMap?

OSM in the media

• Ivan Nechaev, of Georgia Today, reported that the Georgian OpenStreetMap community worked online with 2025 aerial imagery from the National Agency of Public Registry, tracing buildings, checking roads, and adding addresses in Ambrolauri (western Georgia) and the surrounding area.

Other “geo” things

• The Iconoclasistas celebrated 20 years of participatory mapping ►.
• Radio France Internationale reported ► on the digitalisation of documents (including maps, documents, and photos) related to the historic mineral exploration in the Democratic Republic of Congo, which are archived in the AfricaMuseum. According to François Kervyn, a geologist and head of the museum’s Earth Sciences department, the documents were previously available only by special order for researchers, but digitisation is expected to make them more accessible.
• Shachar Maidenbaum has published a study analysing how Israel’s military GNSS spoofing tactics affect local people, eliciting reactions ranging from navigation apps being disrupted, to grocery deliveries being directed out of the country, and users of dating apps matching with people across borders.
• Jennifer Ouellette, of Ars Technica, reported that Japanese researchers have developed the muometric positioning system, an alternative to GNSS that uses cosmic-ray muons instead of radio signals. Muons are highly penetrating, charged particles constantly reaching Earth’s surface from different directions. By placing synchronised muon detectors at multiple locations and comparing the timing and directions of the same muons passing through them, the system can determine their relative positions. This could enable positioning underground, indoors, and underwater, where radio signals cannot penetrate effectively.
• NDR reported that Laura Hantschel, Lukas Hort, Annika Neumann, and Clara Mülle of ‘Pipapo Games‘ have developed MapMap, a cartography-themed puzzle game, during their studies. The gaming community has responded enthusiastically to its release, noting a sudden emerging trend of cartography-themed games. They mentioned another recent example, ‘Beware of the Cartographer‘, which focuses on mapping a mysterious land during the Age of Enlightenment, drawing borders between two warring kingdoms, meeting the locals, and balancing their demands with the requirements of the mission (we reported earlier).
• Duan Yuanqiang and others have updated their S2Coast-2023 dataset (version 3), the first global 10 m resolution coastline dataset derived from enhanced Sentinel-2 composite imagery, under a CC-BY 4.0 International licence. There are polyline and polygon features, modelled tide data for some places, and coastal examples. The OSM coastline dataset was used for validation. The article was published in Remote Sensing of Environment.
• Jules Rumeau has developed Scopus, an HD LiDAR viewer using IGN data that runs entirely in the browser. For a given area, the tool calculates the terrain hidden beneath vegetation and displays it side-by-side with aerial photography. Sunken lanes, low stone walls, ruined huts, and other features obscured by trees in standard imagery become visible within seconds.

My first diary entry. Testing 123

(english below)

JugoTour 26

Am 1.Juli 2026 bin ich zum 20. Mal zu einer kontinentalen Fernradreise aufgebrochen. Dieses Jahr ging es endlich daran, den weißen Fleck auf meiner persönlichen Karte zu füllen: Ich hatte mich noch nie tief in den Balkan getraut. Auch wenn meine Reise 2001 von Israel nach Ägypten und zurück politisch aufregend und fern der EU war, so ist das doch schon fünfundzwanzig Jahre her und die Grenzübertritte im ehemaligen Jugoslawien jedesmal begleitet von einem gewissen thrill: Wird jetzt alles ganz anders sein?
Das Nebeneinander von Islam und Christentum war spannend zu sehen; sehr eindrücklich war auch, die Christen als historische Aggressoren und die muslimischen Gebiete als deutlich entspanntere Gesellschaft zu erleben.

Fokus auf Städte

Ich bin meinem Habitus treu geblieben, eine Perlenschnur durch die Hauptstädte zu fahren und sich nicht aus Liebe zur Natur auf besondere Abwege zu begeben. Trotzdem bekam ich natürlich geologisch allerhand zu staunen. Für die Anreise nach Klagenfurt buchte ich ein Zugticket nach Villach, für die Heimreise bekam ich über Flixbus einen Fernreisebus von HAK gebucht, der mich für 120€ in einem Rutsch mit Fahrrad bis Köln brachte.

Dauer und Übernachtungen

Die Tour mit kleinem Zelt dauerte drei Wochen; übernachtet habe ich meist abseits der Siedlungen, manchmal aber auch in AirB’n’B (Sarajevo) oder privat indoor (z.B. in Skopje), wenn ich spontan abends dazu eingeladen wurde, was häufig vorkam.

Po deseti letech přispívání do OSM mě stále baví objevovat nová místa na mapě. Tak snad mi to ještě chvilku vydrží.

Bonjour, as our gracious hosts like to say.

The French community, together with the university, put together a fun experience. Keep in mind that this is my first (larger) OSM gathering of any type.

As an longtime inhabitant of the forum at c.osm.org I already read a few views on different types of members of our actually very diverse community. While there are quite some typical German Mappers on OSM (mapping away without ever interacting and kinda thinking of OSM as their personal project) there are so many different people out there working with and for OSM.

To all those “brickheads” out there: There’s so much more out there than just your personal interest!

In this first installment of my random musings I’ll just leave a link to a good talk I saw on day one that touches some frequent points of concern:

https://2026.stateofthemap.org/sessions/3GRKKJ/

To all you people in Paris: See you around :)

on 25/8/26, we were a combination of bored enough and annoyed enough to start cleaning up the metadata of german railway stations, so as the track numbers actually appear in clients such as OpenRailwayMap (ORM) ((which we use regularly))

today we are going to formalize the process, also so that our commit history is less tedious to write

–

anything we do which is to further the purpose of creating a basic standard of german railway OSM cartography will be simply marked as “DMC - [bahnhofname]”

and further, in almost every case unless otherwise specified, our information comes from the database within Bahnhof.de supplied by the Deutsche Bahn, and our own knowledge from living within and travelling across germany
