The goal of this project is to maintain a canonical representation of the layers available to OpenStreetMap editors such as iD, Vespucci, JOSM, Go Map!! and Potlatch 2. Both imagery and other raster data that is useful for mapping are within scope of the project. This list is purely targeted at OpenStreetMap and does not include layers only useful for other projects such as Open Historical Map if the layers are not also useful for OpenStreetMap. With the way this list is structured it is easy to combine it with additional layer sources simply by copying the additional sources into their own directory and running make.
