FAQ
DEM to SVGZ Conversion
What are DEM files?
DEM is a text-based digital elevation model format originally developed by the United States Geological Survey (USGS) for its national series of terrain data, and adopted by Natural Resources Canada for the Canadian Digital Elevation Data (CDED) product. A file of this type stores a regular grid of terrain heights derived from topographic maps, aerial photography, or other sources, and is organized into a header record, a series of elevation profiles, and an optional accuracy record. The header describes the quadrangle name, the coordinate system, the units, the corner coordinates, the elevation limits, and the grid spacing. USGS files are distributed as 7.5-minute quadrangles with 30-meter spacing in UTM coordinates, or as 1-degree units with 3-arc-second spacing, while CDED files are based on National Topographic System map sheets and use geographic coordinates.
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.
