hillshading by OpenMapSurfer (MapSurfer.NET rendering)

Hillshading is a technique for creating relief maps, showing the topographical shape of hills and mountains using shading (levels of gray) on a map, just to indicate relative slopes, mountain ridges, not absolute height.

OpenStreetMap data can be combined with relief data in a rendering tool, and several tools support hillshading:

• Shaded relief maps using mapnik a possible set of steps to work with Mapnik
• Mapbox GL JS example
• MapSurfer.NET
• Hillshade tile server
