ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri. ArcGIS was first released in 1982 as ARC/INFO, a command line-based GIS. ARC/INFO was later merged into ArcGIS Desktop, which was eventually superseded by ArcGIS Pro in 2015. [8]
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.
QGIS – Desktop GIS for data viewing, editing and analysis — Windows, Mac and Linux. GRASS GIS – extensible GIS for image processing and analysing raster, topological vector and graphic data. OSSIM – Libraries and applications used to process imagery, maps, terrain, and vector data. Marble – Virtual globe and world atlas.
Server GIS products provide GIS functionality and data deployed from a central environment. ArcGIS Server is an Internet application service, used to extend the functionality of ArcGIS Desktop software to a browser based environment. It is available on Solaris and Linux as well as Windows.
