We live in a world where geographic information systems are at our finger tips and we expect them to be available on demand. If you have ever used the mapping application on your cell phone to ask for your location, or if you have looked up an address on the internet, you have used a geographic information system. We just expect that information to be available, but that infrastructure is not easy to create or maintain. Much of what you study in GIS is how systems like those work and how you can create them. This lesson overviews what GIS is about, shows how prevalent the technology is in society, and discusses the methodologies used in the discipline to solve problems and answer questions.
