A geographic information system (GIS) is a specialized form of an information system.
If you could relate information about the rainfall of your state to aerial photographs of your county, you might be able to tell which wetlands dry up at certain times of the year.
Using GIS technology and water-supplier billing information, it is possible to simulate the discharge of materials in the septic systems in a neighborhood upstream from a wetland.

 Online Encyclopedia and Dictionary - Geographic information system
Geographic information systems technology can be used for scientific investigations, resource management, asset management, development planning, cartography and route planning.
CGIS was the world's first "system" and was an improvement over "mapping" applications as it provided capabilities for overlay, measurement, digitizing/scanning, supported a national coordinate system that spanned the continent, coded lines as "arcs" having a true embedded topology, and it stored the attribute and locational information in separate files.
These systems allow data to be captured in 2 and 3 dimensions, with elevations measured directly from a stereo pair using principles of photogrammetry.

 Geographic Information System - Wikipedia, the free encyclopedia
Geographical Information Science is the science underlying the applications and systems, taught as a degree programme by several universities.
Geographic information systems technology can be used for scientific investigations, resource management, asset management, Environmental Impact Assessment development planning, cartography, and route planning.
Developed by Roger Tomlinson, it was called "Canadian Geographic Information Systems" (CGIS) and was used to store, analyse, and manipulate data collected for the Canada Land Inventory (CLI)—an initiative to determine the land capability for rural Canada by mapping information about soils, agriculture, recreation, wildlife, waterfowl, forestry, and land use at a scale of 1:250,000.

 Board on Geographic Names (BGN)
The U.S. Board on Geographic Names is a Federal body created in 1890 and established in its present form by Public Law in 1947 to maintain uniform geographic name usage throughout the Federal Government.
The Board comprises representatives of Federal agencies concerned with geographic information, population, ecology, and management of public lands.
In this age of geographic information systems, the Internet, and homeland defense, geographic names data are even more important and more challenging.

 Geographic Information System
A Geographic Information System or (G.I.S.) is a computerized mapping system that allows users to join together two types of information, maps and databases.
When this information is linked together in a G.I.S. system, you then have a powerful tool that can be used to study, analyze and investigate the relationships of cartographic features and database information simultaneously.
Once combined, computerized models showing the relationship of cartographic and database information can then be output in the form of maps and reports to assist in the study, planning and decision making process about the project for which all of this data has been compiled.

Geographic information system (GIS) technology can be used for scientific investigations, resource management, and development planning.
While a computer-aided mapping system may represent a road simply as a line, a GIS may also recognize that road as the boundary between wetland and urban development between two census statistical areas.
The information content of the maps has been reduced through the process of generalization in two stages, from 1:100,000 scale on the left to 1:250,000 in the center, then from 1:250,000 to 1:500,00 scale on the right.

 Geographic Information System
A geographic information system (GIS) is a computer-based tool that combines the visual appeal of conventional maps with database operations and statistical analysis.
A layer is a collection of specific elements, such as trees, roads, buildings that can be viewed together with other layers for a complete overview of the area, or separately to give a more specific indication of the presence of that particular element.
GIS stores information about the world as a collection of layers that are linked together by geography.

 What Is GIS?
GIS is a collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
It is an "Information System for Geography." Fundamentally, a GIS is based on a structured database that describes the world in geographic terms.
Maps of the underlying geographic information can be constructed and used as "windows into the database" to support queries, analysis, and editing of the information.

 Geographic information system - Facts, Information, and Encyclopedia Reference article
A geographic information system (GIS) is a system for creating and managing spatial data and associated attributes.
The year 1967 saw the development of the world's first true operational GIS in Ottawa, Ontario by the federal Department of Energy, Mines and Resources.
The development of micro-computer hardware spurred vendors such as ESRI, MapInfo and CARIS to successfully incorporate many of the CGIS features, combining the 1st generation approach to separation of spatial and attribute information with a 2nd generation approach to organizing attribute data into database structures.
