Problem: Supported DTED Level 2 raster datasets don't display in ArcMap or ArcCatalog
ArcMap and ArcCatalog do not recognize DTED Level 2 files, even though they are included, along with DTED Level 1 files, in the Raster Format Browsing list on the Raster tab of the Options dialog box. DTED Level 1 files display fine.
Only the file extension for DTED Level 1 (.dt1) is listed as an extension in the Raster Format Browsing list; thus, DTED Level 2 (.dt2) files will not display.
Solution or Workaround
A workaround is to type the DTED Level 2 file extension in the Raster Format Browsing file extensions list.
- Click the Tools menu and click Options.
- Click the Raster tab.
- Click the 'DTED Level 1 & 2 File Extension' input box and type in the DTED Level 2 file extension next to the DTED Level 1 file extension (*.dt1; *.dt2).
- Click OK.
