What is GIS?

A geographic information system (GIS), geographical information system, or geospatial information system is a system that captures, stores, analyzes, manages and presents data with reference to geographic location.

In the simplest terms, GIS is the merging of cartography, statistical analysis and database technology. It allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

GIS may be used in archaeology, geography, cartography, remote sensing, land surveying, public utility management, natural resource management, precision agriculture, photogrammetry, urban planning, emergency management, GIS in Environmental Contamination, landscape architecture, navigation, aerial video and localized search engines.
