The software component of a traditional geographic information system is expected to provide a wide range of functions for handling spatial data: [11]: 16 Data management, including the creation, editing, and storage of geographic data, as well as transformations such as changing coordinate systems and converting between raster and vector models.
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 ...
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.
Because the world is much more complex than can be represented in a computer, all geospatial data are incomplete approximations of the world. [9] Thus, most geospatial data models encode some form of strategy for collecting a finite sample of an often infinite domain, and a structure to organize the sample in such a way as to enable interpolation of the nature of the unsampled portion.
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.
In order to do that, usually qualitative and quantitative empirical studies are conducted and evaluated. In contrast to that, business informatics researchers mainly focus on the creation of IT solutions for challenges they have observed or assumed, and thereby they focus more on the possible future uses of IT.

The term GIS-Centric, however, has been specifically defined as the use of the Esri ArcGIS geodatabase as the asset and feature data repository central to computerized maintenance management systems (CMMS) as a part of enterprise asset management and analytical software systems. GIS-centric certification criteria have been specifically defined ...
The World Wide Web is an information system that uses the internet to host, share, and distribute documents, images, and other data. [33] Web GIS involves using the World Wide Web to facilitate GIS tasks traditionally done on a desktop computer, as well as enabling the sharing of maps and spatial data. [7]
