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 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]

[2] Although it is a public database, GADM has a higher spatial resolution than other free databases, [3] and also higher than commercial software such as ArcGIS. [4] Those sources are commonly use to complete data analysis with data visualisation such as data plots , choropleth map , etc. [ 5 ] [ 6 ]
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.
A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
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.
