What is the relationship between GIS and GPS?

Precisely, GPS (Global Positioning System) is the United States, a satellite positioning system (there are other countries and regions around the world of satellite positioning systems, such as our country is developed “Beidou navigation and positioning system”). Relative to the GIS, the satellite positioning system for more people are familiar with, has been more and more into people’s production and daily life, such as mapping, field data collection, vehicle navigation, tourism and so on.

Through the GPS receiver can obtain an arbitrary spatial location point coordinate data, can be used to measure when the gun. For the GIS is, GPS provides an extremely important real-time, dynamic, accurate spatial data acquisition method is an important GIS data sources, GPS greatly expands the application areas and application of GIS methods. For GPS it, GIS is an important spatial data processing, integration, and application tools. The two closely together to create and deepen a broader range of space applications.
