[IDV #WAO-360515]: IDV - Error when trying to create display with DEM file

This is the GTOPO30 format which is different from the USGS DEM
format we support.  We hope to add a reader for this format at
some point in the future, but don't have a timeline for that.

You can get a similiar dataset (2 minute vs 30 arcsecond) dataset
from the following location:

http://www.ngdc.noaa.gov/mgg/gdas/gd_designagrid.html

and saving it as a ASCII Raster format.  The IDV can read
that format.
