GIS is a system that stores geographic information used for cartography, creating accurate and layered maps. The World GIS consists of public, private, and government-run databases with information about human and animal habitation, historical data, surface and substrate conditions, or current and historical use of natural resources. GIS cartography focuses on multilayered information allowing users to switch between different overlays. Spatial analysis combines different disciplines to create a database that can be used to make predictions about natural resources in other areas.
A geographic information system (GIS) is a system that stores information relating to the geography and formation of the land. When geographic material is used for cartography, it is referred to as GIS cartography. Maps using GIS systems are often very accurate and contain much more information than a standard map. This additional information is part of a larger process called spatial analysis, in which geographic information is used to create layered two- or three-dimensional representations of real-world locations.
The World Geographic Information System consists of a collection of public, private, and government-run geographic databases. These databases contain a wealth of information about many different parts of the world. At a given point, there may be information relating to human and animal habitation, historical data, surface and substrate conditions, or current and historical use of natural resources.
Information in GIS databases can be used to create maps. Simple roadmaps or political maps are possible, but this is not the essence of GIS cartography. In most cases, to be a true GIS map, it must have additional information beyond that of a regular map. The different information available in the GIS must come together to create a whole experience of the area.
GIS cartography focuses on multilayered information. When a user looks at a map, it might look like a normal topo image. With a few button presses, the user can switch between that map and a substrate, forest cover, roadmap, or any number of other overlays. This allows GIS cartography to investigate the current and historical existence of a segment of territory.
Spatial analysis is the broader discipline of which GIS cartography is apart. This field is a convergence of several disciplines such as geology, computer science, archeology and mathematics. Information from different sources is combined together in one database. When a user calls up a location, he can view it in any number of different ways.
Spatial analysis software allows you to overlay several maps of a place. A basemap, often a topographic map, is used as the base, and other maps showing different types of businesses are placed on top. This convergence of different information will often show patterns that may not have been known before.
These models are used in other places to make predictions. For example, if a specific natural resource was found in multiple locations with similar topography and patterns, it is possible that other similar areas have the same resource. These forecasts are used by companies to limit the cost of researching natural raw materials.
