Hi, trying to gauge the current feasibility of an idea: I'd like to generate a base isometric projection map from OpenStreetMaps data for a major city. I think simply creating a base layer tilemap with green area, lots, and roads would help lay the foundation of a large map project that I'd like to work on with multiple people. Could anyone point me at some info regarding how this base map layer is generated: tile image properties, base layer format, schemas, max sizes, multi-map linking strategies, etc?
