Maps La Mare des Pressoires and Le Petit Chauvet, are parte of project for Balize 77 Club. Located in famous Fontenebleau Forest, these maps are great for orienteering. Many stones, micro-relief and a varied forest make part of this paradise. For these Works, I used as base map oldest existing. For reasons I dont know, in general, these maps have distortion problems. They seem to have been made by parts and then joined. The problem is that this union did not fit well. I had to do a redoubled work.
