According to the SRTM documentation
(http://spatialnews.geocomm.com/features/shuttle/srtmdataupdate03/index.html)
NIMA (now NGA) was to process the SRTM data by putting it into DTED
format among other things and then give it back to NASA for distribution
to the public.
"Data are being mosaicked into approximately 15,000 one degree by one
degree cells and formatted according to the Digital Terrain Elevation
Data (DTED) specification for delivery to NIMA, who will use it to
update and extend their DTED products. ... Following these "finishing"
steps data will be returned to NASA for distribution to the scientific
and civil user communities, as well as the public."
I have downloaded several zip files from the United_States_1arcsec
folder at ftp://e0mss21u.ecs.nasa.gov/srtm/. After unzipping them I end
up with file names that look like this one for example: N31W110.hgt.bin
What happened to the DTED files that I thought I was going to get? Is
there a conversion utility out there that will convert these .bin files
to .dt1 or .dt2 files?
Thanks.
