SUL to CIT Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.

What are CIT files?

A CIT file represents a black-and-white raster image created using an Intergraph Security, Government and Infrastructure (SG&I) piece of software. Until a few years ago, Intergraph was considered one of largest software developers in the world, and is part of Hexagon AB since 2010. The company provides IT services all over the world to governments and businesses, and apart from the SG&I division it also includes one called Process, Power & Marine (PP&M) and another called Hexagon Geospatial.
