What Is GIS?

A Geographic Information System (GIS) is a computer-based tool used to collect, store, analyze, and display information that is connected to locations on Earth.

GIS is used to create maps and analyze data related to places and events. It combines regular database functions, like searching and analyzing data, with map-based visuals. This makes it easier to understand patterns, answer questions, and share information in a clear and visual way.

What is GPS?

GPS uses a network of 24 satellites called NAVSTAR that orbit the Earth about 12,000 miles above the surface. These satellites move very fast—about 7,000 miles per hour—and each one circles the Earth twice every day. The satellites send signals down to Earth, and GPS receivers use these signals to calculate an exact location by comparing the distance from multiple satellites. 

Bringing together GIS and GPS to create Mapping:

First, GPS is used in the field to gather location information. A GPS device or smartphone receives signals from satellites and records the exact position of real-world features, such as roads, buildings, landmarks, or natural features. Each location is saved using coordinates like latitude and longitude.

Next, this GPS data is brought into a GIS system. GIS software takes the collected coordinates and places them on a digital map. The data appears as points, lines, or areas depending on what was recorded. For example, a single location becomes a point, a road becomes a line, and a park becomes an area.

Finally, GIS adds meaning to the map by organizing, analyzing, and displaying the data. Users can add labels, colors, and layers, compare different sets of data, and look for patterns or relationships. This creates clear, useful maps that can be shared and used for planning, navigation, and decision-making.

In simple terms, GPS collects where things are, and GIS turns that information into maps that people can understand and use.
