what OS are you using? What version of GDAL? On Linux I've not had a
problem reading .dt? files.
OpenSuSE Linux 11.0, VPB rev 953, OSG 2.8.0 and GDAL 1.6.0. I'm not
sure how it's working for you if you're using the version of VPB that
checks extensions. Did you modify GDAL to report the .dt? file
extensions?
You are right, I must have used an earlier version of vpb that did read
my files (I have a working DB with the input data as DTED). The newest
VPB ignores my .dt2 files.

It seems that VPB (SVN revision 953) won't accept DTED data.
Looking
at
the VPB code, VPB gets a list of GDAL supported extensions (and adds
a
few that GDAL doesn't report). Looking at GDAL, it fails to report
the
DTED extensions (.dt0, .dt1, .dt2) via the
GetMetadataItem(DMD_EXTENSIONS) method. The result is VPB reports
that
DTED files are not supported. I don't know if the fix belongs in
GDAL
or VPB, but as a quick work-around add the following lines to the
end
of
the VPB System constructor (src/vpb/System.cpp):
addSupportedExtension("dt0", Source::IMAGE | Source::HEIGHT_FIELD,
"DTED
Level 0");
addSupportedExtension("dt1", Source::IMAGE | Source::HEIGHT_FIELD,
"DTED
Level 1");
addSupportedExtension("dt2", Source::IMAGE | Source::HEIGHT_FIELD,
"DTED
Level 2");
Ken.
