This quote means that if you take 80% of all government data, 80% has a geographic context. This quote originated from Robert Williams in his paper “Selling a geographical information system to government policymakers.”[1] But recently, researchers havecut this percentage to 60%in 2012.[2]...
A geographic information system (GIS) is a system designed to capture, analyze, store, manipulate, present and manage all types of geographical data, like information from maps, global positioning systems (GPS) and ubiquitous data, like locations of landmarks and areas hit by calamities. It can...
A geographic information system is critical for modern military operations. This software provides military commanders with critical information on terrain, enemy locations and potential ambush opportunities. In the past military commanders planned command and control operations based on data provided by scou...
Geographic information system(s), GIS (noun) GIS is a technology that is used to create, manage, analyze, and map all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This prov...

Find the definition of GIS. Learn how this mapping and analysis technology is crucial for making sense of data. Learn from examples and find out why GIS is more important than ever.
Geographical Information System (GIS) is a tool on top of a geospatial database to edit and maintain geospatial data. GIS support geospatial objects, which are organized in layers that can be overlaid both visually and logically. Geospatial analysis is about understanding complex interactions based ...
The first GIS was the CGIS (Canadian Geographical Information System). It was developed in Canada in the early sixties by Roger Tomlinson, who is popularly known as the “father of GIS”. In the mid-sixties, two applications, SYMAP and GRID, laid out the theoretical foundation for the anal...
