Re: DTED, RPF woes

The DTEDCoverageLayer works at any scale, in any projection.

Your code worked for me - so the problem must be with how OpenMap is
accessing your data. Make sure your DTED data and directories are in
lower case, and that your RPF data is in upper case. If they aren't,
you can use the com.bbn.openmap.layer.rpf.ChangeCase class to
recursively change them. The DTED layers make the lower case
assumption. The RPF layer looks for whatever is in the A.TOC file, and
that is ~always upper case (according to the spec). The layer does
check for lower case paths, too, just in case, but hey, that may be the
problem. Mixed cases will screw up both layers.

Also, make sure that there is an A.TOC file in the RPF directory you
reference in your path.

If none of these suggestions make a difference, if you send a printout of
> ls -R

of your data, it would help.
