What are GIS Files?

The GIS file format, also know as the Geographic Information Systems file type, is used to store geographical information in a standard encoded format. It is mostly used to store files related to GPS devices and mapping software.

Geographical data is saved in the form of vectors, not pixels, which is comprised of vertices and paths. This geospatial data is then stored in a variety of GIS file formats. This file format is primarily used by government mapping agencies and GIS developers.
