Geographical Information System Administration
GIS (Geographical Information System) is a collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS links a location to information such as people to addresses, buildings to parcels, or streets within a network. Multiple layers of information help give a better understanding of how it all works together. You choose what layers to combine based on what questions you need to answer. GIS also gives you the tools to interpret data, allowing you to see relationships, patterns, or trends intuitively that are not possible to see with traditional charts, graphs, and spreadsheets.
