Geographic information science (GIScience, GISc) or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed.
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.
GIS software distinguishes the interior and the exterior by requiring that the line be ordered counter-clockwise, so the interior is always on the left side of the boundary. In nearly every format, a polygon can have "holes" (e.g., an island in a lake) by including interior rings, each in clockwise order (so the interior is still on the left).

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.
Web GIS (also known as Web-Based GIS), or Web Geographic Information Systems, are GIS that employ the World Wide Web to facilitate the storage, visualization, analysis, and distribution of spatial information over the Internet.
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 ...
