GIS File Types
The GIS (Geographic Information Systems) category includes files related to GPS devices and mapping software. These files may contain maps, saved routes, and waypoints. Many GIS files are saved in open formats, which can be transferred between GPS devices and computer systems.
Common GIS file extensions include .GPX, .LOC, and .OV2.
