GPS (Global Positioning System) consists of 24 satellites in orbit. With appropriate receiving equipment the system can be used to determine geographical co-ordinates such as position and height. There are many uses of GPS including navigation, mapping, surveying, and monitoring. This Open Directory Category is for GPS sites that relate to Geomatics, that is the study and measurement of the physical environment of the earth.- Category ID : 423779

Free multiplatform software converts waypoints, tracks and routes from consumer GPS receivers and popular mapping programs, and allows the data to be manipulated. Handles many file formats.
Global Positioning System satellite ephemerides ("orbits") information for the general public, from US NOAA. GPS precise orbits are derived using 24 hour data segments from the global GPS network. An informational summary file is provided to document the computation and to convey relevant information about the observed satellites, such as maneuvers or maintenance. Orbits generally are available 2 to 6 days after the observation.
Cartographic Software is for making moving maps on which GPS data from a serial port are plotted. Data are tracked remotely via CDPD modems and internet sites.
Suite of data services that brings together the new Earth science products to be produced by spaceborne Global Positioning System (GPS) receivers. It serves mainly as a database for GPS occultation observations.
Software for Windows XP or later that works with digital maps bought or scanned. Imports vectorial and DEM data and also can interface Google Maps and Google Earth.
