FAQ
LOS to IFF Conversion
What are LOS files?
LOS (Longitude Seconds) is a grid file of NADCON, the North American Datum Conversion tool of the U.S. National Geodetic Survey (NGS). It holds the east-west part of the correction that moves coordinates from an older datum, such as NAD27, to a newer one, such as NAD83, and it is always used together with a file of the same name with the .las extension, which holds the north-south part. Each file covers a region, such as the conterminous United States, Alaska, or Hawaii, with a regular net of points, and every point carries a shift in seconds of arc. Surveyors and mapmakers used these pairs for decades to bring older maps and survey records into agreement with modern positions.
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.
