List of GIS data sources. This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
Geographic information system (GIS) is a commonly used tool for environmental management, modelling and planning. As simply defined by Michael Goodchild, GIS is as "a computer system for handling geographic information in a digital form". [1] In recent years it has played an integral role in participatory, collaborative and open data philosophies.
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards ...
Multi-Agency Geographic Information for the Countryside (MAGIC) is a governmental website in the United Kingdom which provides geographic information, in map form.. Launched in 2002, [1] the site originally only had information for rural areas in England but it has grown to include information on a wide range of landscape and environmental designations in England, Wales and Scotland, and cover ...
Information included in the Atlas includes accurate, seamless maps, documentation, and geospatial data that crosses political borders. This data is displayed as series of interactive map layers in an easy to use map viewer format. Most layers in the North American Environmental Atlas are at a scale of 1:1:10,000,000 or finer.

The Vector Map (VMAP), also called Vector Smart Map, is a vector -based collection of geographic information system (GIS) data about Earth at various levels of detail. Level 0 (low resolution) coverage is global and entirely in the public domain. Level 1 (global coverage at medium resolution) is only partly in the public domain.
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [ 1 ][ 2 ] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [ 1 ] In a broader sense, one may consider such a ...
Pennsylvania Spatial Data Access (PASDA), [4] the official public geospatial data clearinghouse for the Commonwealth of Pennsylvania marked its 18th year in 2014. PASDA, which has grown from a small website offering 35 data sets in 1996 to the expansive user-centered data clearinghouse that it is today, has become a staple of the GIS community in Pennsylvania.
