Analysis of the development of open GIS software and QGIS system

Abstract

Abstract. Open source software could emerge thanks to the development of the Internet, development tools, and computer literacy in general. The most attractive parameter of open source GIS software is a free license. The rapid pace of development, attracting developers from all over the world and high modularity stimulate the innovative nature of open source software. Here, the introduction of new technologies does not meet with opposition, but rather welcomes. These circumstances, as well as elucidation of the functional capabilities of such GIS, become very important in the search for means of providing the educational process with modern GIS software, which is traditionally an expensive proprietary software. Goal: Analysis of up-to-date GIS software protection and visual accessibility of the QGIS system in the first place with studying geoinformation systems.Quantum GIS (QGIS) is an open source software (GIS) geographic information system (GIS). Open software is one of the most interesting technological phenomena of the present, owing to its rapid growth in the development of the Internet, development tools and computer literacy in general. The key role in the creation, development and support of open source software is played, as a rule, by the community of developers forming around individual software products: commercial companies, groups of enthusiasts or research organizations. The term open source was proposed by Bruce Perens, one of the key leaders in the Open Source and Free Software movement, cofounder with Eric Raymind in 1998 of the Open Source Initiative (OSI), an open source software development organization that promotes and provides technical open source support. This open source term is used by OSI to determine whether a software license complies with open source standards. The main features of open source software as defined include free distribution, accessible source code, permission to modify this source code. At the same time, even successful open source software products require companies on the market ready to provide technical support and advice on issues related to the selected products. However, the number of companies providing support services for open source GIS software is still relatively small.
