Data sources
The data behind Top-O-Map
Creating a detailed topographic map requires a variety of geographic data. For Top-O-Map, several data sources are processed and combined to provide the most comprehensive possible picture of terrain, elevation, roads, paths, water bodies and other geographic features.
On this page, we want to be transparent about which sources are used in creating and developing the Top-O-Map maps.
