FAQ
ISG to DIS Conversion
What are ISG files?
ISG is a text file format of the International Service for the Geoid, an official service of the International Association of Geodesy, based at the Politecnico di Milano in Italy. The service collects geoid models from many countries and republishes them in this single format, so that users do not have to deal with a different file layout for every country. A geoid model describes the shape of the surface of mean sea level, and it is what allows heights from satellite positioning to be converted into heights above sea level. A file of this type holds the geoid heights as numbers on a regular net of points, accompanied by a header that names the model, its author and year, and the area it covers. Some files also hold models given at scattered points.
What are DIS files?
The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
