What Is GIS?

Dynamic Planet - Smithsonian Institute

A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
It is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

What Is GPS?

The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. Originally intended for military applications,the government made the system available for civilian use in the 1980’s. GPS works in any weather conditions, anywhere in the world, 24 hours a day.

The 24 satellites (NAVSTAR) that make up the GPS space segment are orbiting the earth about 12,000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7,000 miles an hour. GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user’s exact location.The satellites are solar powered.
