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. | |||

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.
Elevation values
Slope values
Aspect values
Each colormap must have a color palette, determining how data are colored, and a data source.determining which data to color.
Palettes
bbbb
Data sources
The colormap palette defines the colormap types:
- Elevation
- Slope
- Aspect
- and the colormap data source defines the data used by the colormaps.
