Elevation and Image Files of the Same Area

If you have both Elevation and Image source files for the same area, the highest resolution file determines the UPP in Project for that area. For example, consider the following files:

§  Elevation File A - UPP = 1

§  Image File B - UPP = 100

The UPP in Project for file B is 64 (next UPP down from 100). TerraBuilder however, always creates the MPT by applying the same UPP in MPT used for file A (better resolution) to file B.
