System for Automated Geoscientific Analyses (SAGA GIS) is a geographic information system (GIS) computer program, used to edit spatial data.It is free and open-source software, developed originally by a small team at the Department of Physical Geography, University of Göttingen, Germany, and is now being maintained and extended by an international developer community.
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.
ArcExplorer is a lightweight data viewer from ESRI for maps and GIS data in these formats: ESRI Shapefile; ArcInfo coverages; ArcSDE layers; Images; ArcIMS Services (e.g., Geography Network sources) ArcExplorer performs a variety of basic GIS functions, including display, query, and data retrieval applications.
The software team made the program flexible enough to be used not just for roads and rivers, but almost any kind of spatial data: provincial boundaries, power-station locations, satellite images, and so on. The program was named JUMP (JAVA Unified Mapping Platform), and it has become a popular, free Geographic Information System (GIS).
Kosmo was implemented using the Java programming language and is being developed from the JUMP GIS platform and a series of free code libraries, all of which are well acknowledged and widely used in different free software projects (for example, Geotools and JTS). It is available for Windows and Linux operating systems.
The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
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 ...
