What is GIS?
Geographic information systems are computer-based systems that facilitate the input, storage, manipulation and output of georeferenced data. Using GIS, one can relate otherwise disparate data on the basis of common geographic location, creating new information from existing data resources. GIS supports interactive query capabilities, together with graphics tools that support flexible color assignments, toggling on and off of features, and panning and zooming.
There are many websites where you can learn more about GIS and other geospatial technologies. A few are listed below:
