Today marks three years since I joined the OpenStreetMap community in May 2023. I am posting this diary entry at the exact time I published my first changeset, which I still remember clearly for its simple message: “add more data.”

It’s a straightforward phrase, but over these three years, it’s really shaped my journey as a mapper. What began as a tiny contribution has blossomed into a deep commitment to mapping my area in as much detail as possible.

Main Objectives


Right now, I’m focused on two main goals for our region:

  • Power Grid: I’m mapping every single power line in Tulcea County, from the high voltage transmission lines to the medium and low voltage lines which provide power to every town and village.

  • Improving Every Town: Besides the infrastructure, I aim to enhance the data for every town in Tulcea County. This involves cleaning up geometry, adding missing POIs, and making sure the map accurately reflects our local communities.
Once I’ve improved every town in Tulcea County and wrapped up the power grid, I intend to shift from regional to national efforts. My aim is to take what I’ve learned here in Tulcea and apply it to bigger projects all over Romania.

There’s a lot to tackle, but as I’ve realized over these three years, the best way to map a country is one node at a time. The upcoming changesets will make OpenStreetMap one of the most accurate maps of Tulcea, providing a level of detail that other commercial map services simply cannot match. I can’t wait to see the map evolve even further.










Removed Plateau Peak Trail. During SAR search (Dec 30) it was discovered the trail was no longer visible on the ground. Parallel trail still visible and provided access to Plateau Peak as verified by GPS.

So here are my experiences in installing Panoramax instance OSM-HR. Ive made this from notes taken at a time, so hopefully I did not miss too much. Let me know if I did.







When I first arrived at DTU, I was surprised to discover that the map quality was largely inferior to the one back in my home country, France, and was lacking a lot of details, the most crucial being emergency-related appliances and infrastructure.

I would have expected a leading engineering university to have correct, if not excellent, mapping across its campuses, but seemingly that is not the case. I was a bit disappointed because if Denmark values inclusive design a lot, at least on paper, there is very little activity to make these accessible infrastructures easily reachable by their main targets. I guess full support for these features might also be lacking across the variety of apps using OSM data (without considering that these apps are not used by the majority of people), but yeah, a bit of a disappointment here.

So I randomly started mapping around DTU campus, sometimes raising awareness among people around me, sometimes being told to “get a life” (jokingly), but in my opinion, volunteering for something collaborative, be it a charity or an online collaborative map, adds a lot of value to one’s life. You don’t do things for yourself only. Okay, it might be a bit addictive at some point, and you might make changes that are so niche that no one cares besides yourself, but hey, the whole point of collaborative initiatives is also to embrace individual particularities, not to merge them into a bland and vague thing. By looking at the map in different places, you can notice tiny subtleties and tiny additions that show people cared. Even 11 years ago, people cared. Who knows, maybe this contributor passed away since then? Nevertheless, their work is still there and will continue to be refined further. And that is truly beautiful, in my opinion.

That’s all for today. See you later, maybe! 💚

Making the Map of India Even More Accurate! 🇮🇳📍

I am proud to share that I have successfully completed 100% of TomTom’s project: “India – POIs Located Not on Buildings.”

The primary objective of this project was to correct Points of Interest (POIs) that were not situated within the accurate footprints of buildings. An accurate map not only enhances navigation but is also absolutely essential for emergency services and local businesses.

Project Highlights:

Mission: Data Improvements

Total Contribution: Successfully fixed 631 out of 734 tasks.

Status: 100% Complete.

It has been a fantastic experience collaborating with the OpenStreetMap (OSM) community to make the map even more reliable.


Mapping isn’t just about finding routes; it’s about helping the world. 🌍📍

I am proud to contribute as a volunteer with United Nations Mappers. I recently achieved Level 5 (Off the Charts). This journey is not merely about statistics, but about reaching out to the communities that need assistance the most.

My Mapping So Far:

Total Swipes: 562+ (For data accuracy)

Total Area: 87 sq. km (Mapped territory)

Projects: Contributed to 9 humanitarian missions

Supported Entities: 2 major organizations

As a volunteer, every swipe I make and every kilometer I map helps facilitate relief operations during times of crisis. 💪

Alright, after successfully updating the boundaries in Bali, now, I’m shifting my focus further east across the Lombok Strait. Next stop: Lombok Island.

For those who don’t know, Lombok is a gem in the Lesser Sunda Islands, famous for the Mandalika International Circuit and its world-class surf breaks. It’s a new major tourist hub that definitely deserves some love on the map. I’ve already spent some time mapping the natural=* and landuse=* in the smaller islands.
Baiklah, setelah berhasil mengupdate batas wilayah di Bali, kini saya alihkan fokus saya ke arah timur melintasi Selat Lombok. Selanjutnya: Pulau Lombok.

Bagi yang belum tahu, Lombok adalah permata di Kepulauan Sunda Kecil, terkenal dengan Sirkuit Internasional Mandalika dan ombak selancar kelas dunia. Wilayah ini bisa jadi pusat wisata baru yang layak mendapat perhatian di peta. Sebelumnya, saya telah memetakan natural=* dan landuse=* di pulau-pulau kecilnya.
