Background
The U. S. Department of Defense, through the National Imagery and Mapping Agency, produces several kinds of digital cartographic data. One is digital elevation data, in a series called DTED, for Defense Digital Terrain Elevation Data. The data is available as 1-by-1 degree quadrangles at horizontal resolutions ranging from about 1 kilometer to 1 meter. The lowest resolution data is available to the public. Higher resolution data is restricted to the U.S. Department of Defense and its contractors.
Determining which files are needed to cover a particular region requires knowledge of the DTED database naming conventions. This function constructs the file names for a given geographic region based on these conventions.
Description
fname = dteds(latlim,lonlim) returns 'Level 0' DTED file names (directory and name) required to cover the geographic region specified by latlim and lonlim.
fname = dteds(latlim,lonlim,level) controls the level for which the file names are generated. Valid inputs for the LEVEL of the DTED files include 0, 1, or 2.
Examples
Which files are needed for Cape Cod.
latlim = [ 41.15 42.22]; lonlim = [-70.94 -69.68]; dteds(latlim,lonlim,1) ans = '\DTED\W071\N41.dt1' '\DTED\W070\N41.dt1' '\DTED\W071\N42.dt1' '\DTED\W070\N42.dt1'
