"Not everyone knows how to get Openstreetmap data for offline use. With these files we want to make Openstreetmap data more accessible to graphic designers and publishers. Starting from a raw database, each map has been given a certain intelligence (layer structure, attributed information, georeferenced, tiled like the levels from OSM) and has been converted for you in such a way that you can edit it easily to your own preferences. These digital maps are ideal for high quality printing or geospatial design projects." See the
