GIS stands for: Geographical Information System It is a computer-based mapping system that can show many different types of data, such as roads, buildings and vegetation on a single map. The first digital map is used to see the South Pole and track where penguins migrate. It shows their 13,000km and tracks what they've done and eaten.

The final map shows the area affected by wildfires last year and the unaffected areas in Schuylkill, Pennsylvania. Climate Scientist Climate scientists use GIS to create maps and diagrams to help people process information about the climate, how it affects us, and how we are altering the.
