What Is Gis And Gps? by agisanalyst(m): 3:26am On Nov 21, 2010 |
Global Positioning System (GPS) GPS is a passive, all-weather, 24-hour global navigation satellite system (GNSS) operated and maintained by the Department of Defense (DoD), USA. It consists of a nominal constellation of 24 satellites in high altitude orbits. Its primary mission is to provide passive, real-time, 3-D positioning, navigation and velocity data for land, air, and sea-based strategic and tactical forces operating anywhere in the world. A secondary--and most predominant--application is a wide range of civil positioning and time transfer. Geographic Information System (GIS) GIS is a geographic information system, is a collection of computer hardware, software, and geographic data for capturing, storing, updating, manipulating, analyzing, and displaying all forms of geographically referenced information. |
