[aprssig] [APRS] APRS in caves! (mammoth map)

Any chance of getting the underlay _without_ the contour lines, but just the cave and the corner coordinates? With this map, there's no easy way to separate the above-ground elevation contours from the cave tunnels.

Also, is this just the first level of the cave, or is it several vertical levels drawn together?

Mammoth cave underlay on local terrain map is now complete.  The map has a
LAT/LONG grid on the sides so one can pinpoint one's position into the HT
underground to the same 0.01 Minute of LAT/LONG as on the surface.

See http://aprs.org/cave-link.html

So far, none of the modern clients seem to do GIF or JPG files.  But as we
get closer to the 2 March 2013 test, maybe someone can develop a vector
overlay for the main passage.  Can YACC or APRSIS32 do APRS Overlays?
