Is there any way to export elevation data to DTED to higher resolution than DTED2?
Best regards

There is not currently support for exporting DTED files with higher resolution than DTED2. If you can find a format specification that actually describes DTED3 and higher, we'd be happy to add support. Any sample DTED3 and higher files would be useful as well.
Thanks,

OK, thanks. I will try to get some samples for you.

At the moment, the only levels in the "official" spec are: 0,1,2. 3,4,5 have been proposed as such:
post Ground
DTED spacing Dist. row x column tile size
level
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 3.0 sec ~100 m 1200 x 1200 1 x 1 degree
2 1.0 sec ~30 m 3600 x 3600 1 x 1 degree
3* 0.3333 sec ~10 m 900 x 900 5 x 5 minute
4* 0.1111 sec ~ 3 m 540 x 540 1 x 1 minute
5* 0.0370 sec ~ 1 m 810 x 810 30 x 30 second

I think the one that Mats would be interested in most is level 3. :-) -
I have the proposed level spacings for 3, 4, and 5, already in Global Mapper, the problem is that some other format changes will have to be made in DTED to accomodate these changes, but the other required changes have not (to my knowledge) been documented. Has anyone actually ever seen a DTED3, 4, or 5 file?
Thanks,
Mike
