HGT to HPG Conversion
What are HGT files?
HGT (short for height) is the file extension of elevation data from the Shuttle Radar Topography Mission (SRTM), a NASA mission of 2000 that mapped the terrain of most of the world, from about 56 degrees south to 60 degrees north. The data are cut into tiles, each covering exactly one degree of latitude and one degree of longitude, and every tile is a separate file. The name tells where it belongs: for example, N20E100.hgt covers the area from 20 to 21 degrees north and from 100 to 101 degrees east. The file itself contains only the heights in meters, with no other information. The data come at two levels of detail, about 90 meters per cell and about 30 meters per cell, and they are in the public domain.
What are HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
