FAQ
RIK to CG4 Conversion
What are RIK files?
RIK is a raster map format used for digital maps issued by Lantmäteriet, the Swedish national mapping, cadastral, and land registration authority. A file of this type holds a map as a picture, in which each point is one of up to 256 colors, together with the information needed to place it on the ground in the Swedish national grid. The format exists in three versions, and files of all of them are found in collections of Swedish topographic and general maps, which were distributed on discs and used in navigation programs, hiking and orienteering software, and ordinary mapping systems. Because it is a specialized national format, ordinary image viewers cannot open it, and conversion is the practical way to use such maps elsewhere.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
