#2 - Three years of OpenStreetMap

Posted by 00-sq on 8 May 2026 in English.

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.

A few kilometers from the town of Luncavița in Tulcea County, tourists visiting the Măcin Mountains National Park can stop off in Cetățuia hamlet — a paradise for beekeepers who have brought bees to the linden forests (that define this hamlet) and for tourists who want to stay in a quiet place, next to the mountains, as this is the only locality in Tulcea County that resembles a mountain village. However, it didn’t have detailed OpenStreetMap coverage, until now. We have mapped this area in detail and are pleased to announce that the map is complete. You can view the before-and-after images below.
