Re: Radar mosaics

Gregg,

You can get the distribution via the web. If you are running Linux,
then the easiest way would be to grab the binary and take the programs
from bin/linux. Also, you will need the $GEMTBL/unidata directory for
nex2image to place the appropriate platformID and calibration numbers in
the GINI header (Also grab the entries from $GEMTBL/sat/imgtype.tbl and
the color enhancements from $GEMTBL/luts mentioned in the imgtype.tbl file).

With NCEP's plotting, you won't get a calibration bar from the GINI.
Our distribution has additional code to create read the calibration
section from the GINI.
