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.
The system handles a variety of spatial input formats including shapefile, GeoTIFF, web map services , ESRI REST services, georeferenced YouTube videos and Picasa photos, and GeoRSS feeds. A user can select several local or remote data layers to overlay and control the transparency of overlaid layers, allowing for visual investigations of ...
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products . [ 1 ]
The list of national coordinate reference systems (CRS) lists map projections officially recommended for existing countries.Given that every projection gives deformations, each country's needs are different in order to reduce these distortions.
GADM is not freely available for commercial use. The GADM project created the spatial data for many countries from spatial databases provided by national governments, NGO, and/or from maps and lists of names available on the Internet (e.g. from Wikipedia).
The following is an alphabetical list of subregions in the United Nations geoscheme for Africa, used by the United Nations and maintained by the UNSD department for statistical purposes. [ 1 ]
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.
Location information (known by the many names mentioned here) is stored in a geographic information system (GIS). There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data.
