Is GIS related to GPS?
GPS stands for Global Positioning System. A GPS consists of three parts: The 24 satellites orbiting the Earth, a portable receiver that you carry and the control center that is responsible for maintaining the satellites. A GPS receiver uses the satellites to collect position data on Earth (like latitude and longitude coordinates). You can output the data from the GPS to a file which then can be imported into a GIS. Once in the GIS, the data can be mapped to show the position of data. GIS uses GPS data to locate objects and collect information. The city uses GPS to locate objects such as street lights, signs, curbs, bus stops, etc. and brings that information into the GIS for analysis and mapping.
