FAQ
DEM to IFF 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 IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
