What is GIS?
A geographic information system (GIS) is a system designed to store, edit, analyze, manage, and display all types of geographically-referenced data. In the simplest terms, GIS is the merging of maps, databases, and analysis. Web GIS, a specialized extension of GIS, takes GIS data and functionality to a larger audience through the Internet.
A GIS can be thought of as a system — it digitally creates and “manipulates” spatial features that may berelated by proximity, purpose, or application. A GIS is usually application specific, developed for a particular role or purpose, such as municipal management, emergency response, forestry, mining exploration, transportation networks, public utilities, and a myriad of other applications that rely on spatial data.
Therefore, in a general sense, the GIS term describes any information system that uses information. The main purpose of a GIS is to provide information to enable better decision making. GIS applications are tools that allow users to create interactive queries (user-created searches), analyse spatial information, edit data, maps, and present the results of all these operations.
