Figure: Geographic Process
What distinguish GIS from other information systems are its spatial ANALYSIS functions.
Major components of GIS.
Figure: Gamma-ray remote sensing of soil properties in a forested area near Batlow, NSW.
Try looking up different definitions of GIS, there are many! Note: always check online references are from a credible source Example of common spatial reference: Latitude/Longitude (degrees)
Figure: Light Detection And Ranging (LIDAR) example of Mayan ruins, a recent development in remote sensing, a major source of GIS data, which allows very high accuracy (+/- mm’s)
