Geographic Information Systems, GIS
1. The computer hardware, software, and technical expertise applied to assemble and to analyze geographical data; especially, the correlation of databases with graphic displays to present information; frequently employed in environmental studies.
2. An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information which can be drawn from different sources, both statistical and mapped.
3. Computer programs linking features commonly seen on maps; such as, roads, town boundaries, and water bodies, with related information not usually presented on maps; for examlple, type of road surface, population, type of agriculture, type of vegetation, or water quality information.

GIS is a unique information system in which individual observations can be spatially referenced to each other.

4. A technology that is used to view and analyze data from a geographic perspective. The technology is a piece of an organization's overall information system framework.

GIS links locations to information; such as, people to addresses, buildings to parcels of land, or streets within a network, and layers that information to give a better understanding of how it all interrelates. The user can than choose which layers to combine based on his/her purpose.

geographic speciation (s), geographic speciations (pl) (nouns)
The evolutionary development of plant or animal groups whose members all have similar general features and are able to produce young plants or animals together: "An evolutionary change leading to the rise of new species resulting from the separations of biological populations into mutually exclusive geographic regions, thereby creating distinct gene pools."

"Differentiation of populations of biological groups in various geographical isolations to the point where they are recognized as separate species."

geographical coordinates, geographic coordinates; terrestrial coordinates
1. The world-wide system of latitude and longitude used to define the location of any point on the earth's surface or to designate both geodetic coordinates and astronomical coordinates.
2. The quantities of latitude and longitude which define the position of a point on the surface of the earth with respect to the reference spheroid.

geographical cycle, geographic cycle; geomorphical cycle, geomorphic cycle, cycle of erosion
1. Theory was developed or formulated by the American geographer and geomorphologist, William Morris Davis (between 1884 and 1934), who modeled the formation of river-eroded landscapes.

This theory suggests that landscapes go through three stages of development (youth, maturity, and old age) and indicates that the rejuvenation of landscapes arises from tectonic uplift of the land.

In the "youthful stage", under the influence of tectonic uplifts, there appears a mountain relief, which is dissected through erosion (the washing out of rocks by rivers) into deep, narrow valleys and sharp-peaked ridges.

With the dissection by streams, the area would reach maturity and, ultimately, would be reduced to an old-age surface called a peneplain (gently undulating, almost featureless plain), with an elevation near sea level.

The model developed by Davis, though important in historical context, is currently considered only a first approximation.

Developments in the sciences of geology and geomorphology, especially the plate tectonics revolution of the 1960's and 1970's, have confirmed the preliminary nature of the model.

geographical distribution of resources, geographic distribution of resources
The physical character and distribution of natural resources on the face of the earth.

The fundamental differences between land and ocean, latitudinal differences in insulation, spatial variations in receipts of precipitation, and patterns of geological composition, and deformation of the earth's crust together provide the basis for distinguishing definite geographical patterns of resource availability through out the world.

geographical information system, geographic information system, GIS
1. A computer system specialized for the storage, manipulation, and presentation of geographical information; such as, topography, political subdivisions, geology, vegetation, flood plains, etc.
2. A computerized system which relates and displays data collected from a geographic entity in the form of a map.

The ability of a geographical information system to overlay existing data with new information and display it in color on a computer screen and is used primarily to conduct analyses and make decisions related to geology, ecology, land use, demographics, transportation, and other domains, most of which relate to the human use of the physical environment.

Through this process of geocoding, the geographic data from a database is converted into images in the form of maps.

geographical range, geographic range
1. A spatial distribution of a species (group of interbreeding organisms that do not ordinarily breed with members of other groups) in which the geographic ranges of species often fluctuate over time.
2. The total area occupied by a population.
3. The extreme distance at which an object or light can be seen when limited only by the curvature of the earth and the heights of the object and the observer.

geographical unit, geographic unit
An area based primarily on hydrologic boundaries adjusted as needed using a specified set of criteria to accommodate the inventory and analysis of natural resources.

A geographic unit can vary in scale depending on the criteria used, the level of inventory and analysis needed, and the problems perceived. In all cases, geographic units incorporate both groundwater and surface water.
