5.0 3D DEM data issue

, re-post in this zone.
_____________
Hi,
I like the 3D fuction in Oruxmpas 5.0. It works well with .hgt file download from NASA website. While, SRTM v2 data (GeoTiff format) is better, which "modifed" some "holes" data in .hgt files. i am in China, it is important.
I knew 5.0 can not support SRTM GeoTiff directly, so i transfered them to .dem, unfortunately, Oruxmaps still says "no 3d data". I copied a .hdr into the dem directory, 3d model can work, but it show a "flat" map.
Note, i used global mapper 14 to export .dem file, which includes necessary map info. it could be opened in GM without .hdr.

Hi;

there are many varieties of dem files.

if you send me the HDR, I can investigate where the problem is.--> oruxuro@gmail.com

might it not be using the hdr geographic coordinates (UTM, for example).

If you think Global Mapper is the problem, you can transform Geotiff to HGT format with GDAL
"gdal_translate -of SRTMHGT ASTGTM2_N000E000_dem.tif N000E000.HGT"
SRTMv2 GeoTiffs should be the same format as ASTER Geotiffs: both are provided by NASA.

Thanks a lot.
