I have openmap installed at C:\Apps\openmap-4.6.2\. The DTED 0 and 1
data is in
C:\Apps\openmap-4.6.2\share\data\dted
This directory has files:
n33w112.dt0
n33w112.dt1
And subdirectories
w112
n33
Both of which also have copies of the .dt0 and dt1 files listed above.
The dted data files are for 33N, 112 West region, which is roughly the
Arizona / Mexico border. When I open the .dt1 file in MicroDEM, I see
reasonable looking terrain at the expected location, so the data files
themselves are OK. I'm guessing that there something about their
placement, name or some openmap dted properties that aren't quite right.
The dted layer is loaded at startup, and I pick a CADRG projection from
the Projections submenu.
If I zoom in on lat / long 33, -112 all the way to 1:500 and then back
out again I never see the dted terrain I see in MicroDEM. I have
appended the relevant bits from my openmap.properties file below.
Any suggestions as to what to try next to see the terrain data?
Thanks,
Chris
