NAME
m.dted.examine - Provides a terse description of
level 1 and 2 digital terrain elevation data (DTED) files
produced and distributed by the Defense Mapping Agency
(DMA) on 1/2-inch magnetic tapes.
(GRASS Data Import/Processing Program)
SYNOPSIS
m.dted.examine [tapedev]
DESCRIPTION
m.dted.examine scans digital terrain elevation
data (DTED - Levels 1 and 2) that was produced and supplied
by the Defense Mapping Agency (DMA) on 1/2-inch magnetic
tape from the tape device specified by tapedev,
and prints to the screen a terse description of each file.
If the user specifies no tapedev on the command
line the program assumes that input is coming from
/dev/rmt0. The information provided by
m.dted.examine includes the UTM borders, cell
resolution, and number of elevation profiles in each file.
BUGS
The header file for DTED Level 1 and 2 data was changed in 1987.
m.dted.examine and
m.dted.extract
operate only on DTED data containing pre-1987 headers.
DTED data containing the pre-1987 headers may be purchased
from the Defense Mapping Agency (DMA) upon request.
