A geoportal is a type of web portal used to find and access geographic information (geospatial information) and associated geographic services (display, editing, analysis, etc.) via the Internet. Geoportals are important for effective use of geographic information systems (GIS) and a key element of a spatial data infrastructure (SDI).
Free and open-source software portal; This is a category of articles relating to GIS software which can be freely used, copied, studied, modified, and redistributed by everyone that obtains a copy: "free software" or "open-source software".
The distinction must be made between a singular geographic information system, which is a single installation of software and data for a particular use, along with associated hardware, staff, and institutions (e.g., the GIS for a particular city government); and GIS software, a general-purpose application program that is intended to be used in ...
Integrated Land and Water Information System (ILWIS) is a geographic information system (GIS) and remote sensing software for both vector and raster processing. Its features include digitizing, editing, analysis and display of data, and production of quality maps.
The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains international standards for geospatial content and location-based services, sensor web, Internet of Things, GIS data processing and data sharing.

This is a comparison of notable GIS software. To be included on this list, the software must have a linked existing article. The selection of GIS software is a non-trivial task typically undertaken at project commencement. The use of appropriate selection criteria and methodology can be critical to a project's success, with considerations including outlay costs, ease of use, data and system ...
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important.
The basic data is overlaid with graphic styles (e.g. colour shades, hatch patterns) to display information on a more sophisticated level. For example, population density between urban and rural areas may show the cities in deep red (to indicate a high ratio of inhabitants per square mile), while showing remote areas in very pale red (to ...
