On these pages you will find the three elevation files of each United
States Geological Survey 1° by 1° 1:250,000 scale topographical
map sheet in the State of Nebraska. Vistapro is a low cost pseudo
3-D terrain modeling software package available from
Virtual Reality Laboratories, Inc.
The files have been compressed with the MS-DOS utility PKZIP ver 2.04g
available from PKWARE®, Inc.
The only difference between the three versions are the size of the files.
The first is 258x258, which corresponds to Vistapro small
DEM size; the next is 514x514, which corresponds to Vistapro
large DEM size; the last is 1026x1026 which is Vistapro's
huge DEM size. CASDE teachers please read

The download page is available in a text only
