Use of cadastral data from Агенция по геодезия, картография и кадастър on OSM

Great news! I think 2 steps should be taken now:

  1. get confirmation from the legal people of OSM that we can indeed use these data, see DGU spatial data under Open License compatible with ODbL?
  2. discuss how we can use these data in the best possible way. I think a tool should be developed that conflates the data from АГКК with the data we already have on OSM so that it flags conflicting data and allows a human to decide what to do, taking into account that the АГКК is full of mistakes too. I have some experience in using АГКК data manually so I can contribute, though not with coding because I don’t have those skills. We would need feedback from АГКК to understand their “tagging” practice and compare it with ours, so we need to contact them and start a cooperation. It should be interesting for them to get our feedback too; we can help them find mistakes in their data and improve their data quality. The Dutch OSM community might be able to share their experience (see BAGimport - OpenStreetMap Wiki). Grants might be available for someone who can spend time on coding this tool.

Maybe someone can create separate topics for each of these 2 items?

This forum is about Bulgaria so should be in Bulgarian. It’s me who should be ashamed of being so lazy to write in English :smiling_face:
