GPS Global Positioning Systems
GPS is a satellite-and-ground-based radio navigation and locational system that enables the user to determine very accurate locations on the surface of the Earth. GPS technology can range from highly sophisticated and detailed to the centimeter to fairly simple and inexpensive with accuracies of 10 to 20 meters.

Satellite Imagery
and Remote Sensing
Remote sensing captures images of the earth's surfaces via satellites or airplanes. Remote sensing can use multispectral bands to collect images of physical landscapes to show changes as a result of humaninteraction or natural occurrences. You can use remote sensing to study: 1) urban heat islands, 2) flood analysis, 3) rangeland management, and 4) population estimation.

Geographic Information Systems
GIS applications are able to store, manage, and analyze large quantities of spatially distributed data. The data is layered and used for such things as placement of retail stores, homes that may be in danger of mudslides, emergency services, and many more.
Maps
Maps are the number one tool geographers use most. Whether they are created through information collected with a hand-held GPS unit, or hand drawn, maps represent the spatial distribution and locations. Maps enable geographers to use spatial analysis to answer questions.
