All the 'GDAL formats' (raster formats) are here http://www.gdal.org/formats_list.html. (3) DTEDO0, DTEDO1 and DTEDO2 (4) GeoTIFF (5) DTED are the supported formats.
The military format specification (MIL-PRF-89020B) for the Digital Terrain Elevation Data (DTED) is available in a multitude of locations, including the NGA reference site and at the USGS (which publishes some SRTM data in DTED format). The DTED Level 0 data is relatively small, and is often published as a concatenation of large area or global tiles (in ...
The GDAL section of the Options from the Settings menu will tell you which raster file formats GDAL in your QGIS can load. I can't find a corresponding list for OGR (vector) drivers, but the popup on the "Load Vector Layer" probably has all the file-based ones:
in qgis, you can see your dted files as contour map or hillshade map, if it helps. for converting your file to contour: Raster → Extraction → Contour for converting it to hillshade: Raster → Analysis → DEM (Terrain Models). This examples from Paulina Fernandez Luengo which shows hillshade and contour map together. i hope it helps you...
DTED is the name of a data format. As mentionned by @Vince, it is also used as a data name (I didn't know that) but most of the time it is associated with SRTM data. If you are looking for free DEM, use the SRTM DTED1(see cgiar or on earthexplorer). It is DTED1 (not 0) but higher spatial resolution is often useful. For low resolution you also have ...
I think it is GDAL (isn't it always) using translate. Below is close gdal_translate -of SRTMHGT input.dt1 output.hgt You will find limitations on both these formats though so read up. Here are you binaries.
I have written GDAL programs using C++ and C#. It is incredibly easy to use. I advise you to download the source code. You'll find the source for gdallocationinfo, which is their command-line tool that does exactly what you want. You can use it as the lever to get going. If using gdallocationinfo on the command line won't work for you. -reilly.
SRTM is a data product, while DTED is a data product and a transfer format (MIL-PRF-89020B). SRTM data in DTED format can't be easily distinguished from DTED (it wouldn't be of much use to DTED readers if it were).
There is no "official" standard beyond DTED2 (yeah, citation needed...). There is data beyond that, but acceptance of that data is patchy. For a sample of DTED3, see http://www.falconview.org/trac/FalconView/downloads (Link 20 - DTED3 for the Boulder area).
I solved my problem and recorded the solution (with code) in the ArcGIS Discussion Forums: First, you should create a IRasterCollection and add some IRasterDataset into it. Then you should create ISaveAs2 and cast rc to it. Then create IRasterStorageDef stuff. Finally, use ISaveAs2's SaveAsRasterDataset function to save merged/mosaicked ...
GRASS GIS supports about 80 raster formats including various DEM and DTED formats. You can do it all via a convenient wizard: http://grasswiki.osgeo.org/wiki/GRASS_Location_Wizard#Import_raster_data
