The Export DTED command allows the user to export any loaded elevation grid data sets to native format DTED files. DTED files support a set of fixed resolutions (i.e. DTED levels) which are defined as aligning on particular boundaries. When you select the DTED level to export to and the export bounds, this defines which DTED tiles need to be generated to conform to the DTED standards for that level. The filename that you select for the export is used as a base, with the lat/lon coordinates of the southwest corner of each tile appended to each filename as it is exported. You can also option choose to split up the exports by longitude into separate folders, in which case the longitude is used as a folder name and the latitude appended to your base filename for each exported cell.
When selected, the command displays the DTED Export Options dialog which allows the user to setup the export. The dialog consists of a DTED Options panel which allows the user to set up the DTED level and other options, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
ADVANCED USERS: You can change the accuracy value exported in DTED files by specifying your own string value (up to 4 characters in length) at "HKEY_CURRENT_USER\Software\Global Mapper\DTEDAccuracy". The collection system value (up to 12 characters in length) can be specified at "HKEY_CURRENT_USER\Software\Global Mapper\DTEDCollectionSystem".
