Contemporary Tools

Learning objectives: The student will be able to identify and discuss contemporary analytic tools in mapping the earth’s surface.

GIScience Geographic Information Science (GIScience): “Involves the development and analysis of data about Earth acquired through satellite and other electronic information technologies” (Rubenstein, 2012, p. 12). Most accurate form of mapping and complex Created by Satellites that sends information to Earth.

Remote Sensing Remote Sensing: “The acquisition of data about Earth’s surface from a satellite orbiting Earth or from other long-distance methods” (Rubenstein, 2013, p. 12). Sensors include photographic images, thermal images, multispectral scanners, and radar images. Data, not information.

Geographic Information System (GIS) GIS: “a computer system that captures, stores, queries, analyzes, and displays geographic data” (Rubenstein, 2013, p. 12). Mathematical precision used and stored in a computer Layers are created upon one another to create a precise image. Layers can be combined to show information

GIS Contains Multiple Layers

GPS (Global Positioning System) GPS: “the system that accurately determines the precise position of something on earth” (Rubenstein, 2013, p. 12). Three main elements: Satellites placed in predetermined orbits by the U.S. military (24 total, 3 in reserve) Tracking stations present to monitor and control satellites A receiver locates at least 4 satellites, figures out the distance to ach, and uses this information to pinpoint location.
