DT0 to PGM Conversion
What are DT0 files?
DT0 is the file extension for Level 0 of Digital Terrain Elevation Data (DTED), a gridded elevation product defined by the U.S. National Imagery and Mapping Agency, now the National Geospatial-Intelligence Agency (NGA), in the MIL-PRF-89020 specification. A file of this type covers one degree of latitude by one degree of longitude and holds elevation values at a post spacing of 30 arc-seconds, which corresponds to roughly one kilometer on the ground. Higher levels of the same series use the .dt1 and .dt2 extensions, with spacings of 3 and 1 arc-seconds. Each file starts with header records that describe the cell origin, the data set identification, and the accuracy of the data, followed by the elevation grid. DTED is widely used in military, aviation, and civil mapping applications, and Level 0 data is publicly available.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
