HGT to SVGZ 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 SVGZ files?
SVGZ is an extension attached to SVG (Scalable Vector Graphics) images with GZIP compression. Such files can contain animations or interactive graphics, including vector objects, images and text, while supporting layer rendering, transparency, filter effects and several other features. As a version of SVG, the SVGZ format is based on an open standard and uses the XML markup language, being supported by most web browsers. The main advantage of SVGZ over its uncompressed variant is size, which can be 20 to 50 percent smaller.
