    Hello,

    I don't know what a Height Error Map is, but you can compare two elevation layers to produce a third elevation layer that represents the differences between them.  Is that what you need to do?  If so, on the main menu, use the Analysis | Combine/Compare Terrain Layers... function.  If not, please post a more detailed description of a Height Error Map so we can determine whether or not there is existing functionality that will do what you need.

    Cheers,

    Bob
