GIS is an information system that collects, displays, analyzes and manages all types of data.
GIS links data to a map by integrating location data (where an object is located) with all types of descriptive information (what exactly is there). It provides the basis for mapping and analysis that are used in science and in almost all branches of the economy. GIS helps users understand patterns, relationships, and geographic context. The benefits of using the system are: improved communication and efficiency, as well as effective management and decision making.
