New Post: Altitude (quotas)

There is hardly any specific altitude related functionality. MapWinGIS can process shapefiles with Z and M values but those values aren't used during rendering. Obviously altitude can be stored as an attribute of vector layer and color scheme can be built based on it. For raster layers there is so called hill shading algorithms, that simulates the lighting source and relief of the territory even if the data doesn't actually represent altitude.

Hope it helps,
