Elevation File Repository

The following are elevation files in BT format, compressed as ZIP files.  They have been processed with VTBuilder and are ready for use with Enviro or any other program which uses elevation data, especially those that use continuous LOD.  The first group of files is plain elevation, useful for testing.  Some of these files are also in the VTP distribution.
