What is a GIS?
A geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and happen on the surface of the Earth. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization offered by maps. These abilities distinguish GIS from other information systems and make it valuable for explaining events, predicting outcomes, and planning strategies. Mapmaking and geographic analysis are not new but a GIS performs these tasks better and faster than conventional manual methods. Before GIS technology, only a few people had the skills necessary to use geographic information to help with decision making and problem solving.

What makes up a GIS?
A working GIS integrates five key components: hardware, software, data, people, and methods. Hardware is the computer on which a GIS operates. GIS software provides the functions and tools needed to store, analyze, and display geographic information. Geographic data (layers) and related tabular data are necessary in order to perform work in a GIS software. GIS technology is of limited value without the people who manage the system and develop plans for applying it to real-world problems. Lastly, a successful GIS operates according to well-designed plans and business methods, which are the models and operating practices unique to each organization.

What is a GIS layer?
A GIS stores information about the world as a collection of layers that can be linked together by geography. This simple but extremely powerful and versatile concept has proven invaluable for solving many real-world problems such as the tracking of delivery vehicles, recording details of planning applications, as well as modeling global atmospheric circulation.
