Thank you very much and indeed the .crt file which was not good I have started to understand it works. I think I’m going to have to do a tutorial for the French because I don’t seem to be able to find anything. My idea is that they should stop mapping data that is already on OSM and then adapt it to mapping on OSM because at the moment they don’t see the point as they’re redoing everything on oomapper.

Hello, I’m taking the liberty of popping in again because I’m very interested to know how you go about importing data from OSM into oomapper. I have several orienteering organisers who have contacted me because they think it’s a shame to redo mappy on data that already exists in OpenStreetMap. They contacted me because I contribute to my region in France and I do orienteering from time to time.

If there is a tutorial, thank you in advance.
