As a terrestrial RF propagation modeling tool, TAP™ requires local elevation data in order to perform propagation calculations. The more accurate the elevation data, the more accurate the TAP™ field strength predictions will be. Digital elevation data are available from a wide variety of sources; however, many SoftWright customers choose to purchase topographical data directly from SoftWright. These data are shipped along with the software at the time of purchase. Depending on the size of the data file, it is provided on DVD or USB hard drive for use with TAP™.
SoftWright currently offers elevation data of 1/3 second (~10m) resolution (or better) in FLT format for the United States and SRTM 1 second (~30m) resolution (or better) topographical data for the rest of the world. SoftWright also offers Land Use – Land Cover data for the United States and most of the rest of the world. These data are guaranteed to work with TAP™ software.
