Colormap layers are single channel data layers, for example elevation data, or data such as census, clutter, etc, which are colored according to a color palette. Values in the data are matched with colors in the palette. Colors may be mapped directly to data values, or there may be a calculation involved. It is for example possible to assign colors based on slope (gradient) or aspect (direction of slope) of elevation data sets.


Each colormap must have a color palette, determining how data are colored, and a data source.determining which data to color.

Data sources

The colormap palette defines the colormap types:

  • Elevation
  • Slope
  • Aspect
  • and the colormap data source defines the data used by the colormaps.
