[Gdal-dev] SRTM file format

[Ben Discoe]

Indeed, it was discussed on the VTP list, and support for .hgt was 
added to the VTP software.  VTBuilder can now read .hgt automatically 
(no need to enter dimensions, etc. as with other raw files) in 
addition, of course, to all the other GDAL-supported formats.
