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.
GeoDa is a free software package that conducts spatial data analysis, geovisualization, spatial autocorrelation and spatial modeling. It runs on different versions of Windows, Mac OS, and Linux. The package was initially developed by the Spatial Analysis Laboratory of the University of Illinois at Urbana-Champaign under the direction of Luc ...

QGIS is a geographic information system (GIS) software that is free and open-source. [2] QGIS supports Windows, macOS, and Linux. [3] It supports viewing, editing, printing, and analysis of geospatial data in a range of data formats. Its name comes from an abbreviation of its previous name, Quantum GIS.
[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]
GRASS GIS contains over 350 modules to render maps and images on monitor and paper; manipulate raster and vector data including vector networks; process multispectral image data; and create, manage, and store spatial data. It is licensed and released as free and open-source software under the GNU General Public License (GPL).
MySQL – Allows spatial querying and storing of most spatial data types. Microsoft SQL Server (2008 and later) – GIS products such as MapInfo and Cadcorp SIS can read and edit this data while Esri and others are expected to be able to read and edit this data at some point in the future. Oracle Spatial – Product allows users to perform ...
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.
