This can include static and moving data, maps, satellite imagery, crowd-sourced data, full motion video, weather data and terrain elevation in many different geodetic references and map projections. Geo-fencing, line-of-sight calculations, geo-triggered events, dynamic and complex route calculations and automated anomaly detection are just a ...
Whitebox GAT contains more than 385 tools to perform spatial analysis on raster data sets. The following is an incomplete list of some of the more commonly used tools: GIS tools: Cost-distance analysis, buffer, distance operations, weighted overlays, multi-criteria evaluation, reclass, area analysis, clumping
Free and open-source software portal; This is a category of articles relating to GIS software which can be freely used, copied, studied, modified, and redistributed by everyone that obtains a copy: "free software" or "open-source software".

OpenStreetMap (abbreviated OSM) is a free, open map database updated and maintained by a community of volunteers via open collaboration. [4] Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources.
SaTScan employs scan statistics to identify clusters of space and time phenomena. [1] Scan statistics use regular shapes (usually circles) of varying sizes to evaluate a study area. [ 8 ] [ 9 ] Within each circle, the software computes if the phenomena within the circle is significantly different than expected compared to the area outside the ...
GeoMedia Essentials, allows for dynamic, complex and ad hoc query and perform basic spatial analysis of vector geospatial data across various data sources as well as create layered maps; GeoMedia Advantage, adds to the functionality of Essentials by adding terrain and grid functions which will allow for additional analysis on digital elevation ...
