## 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.
