A Geographical Information System (GIS) is an information system for organizing and displaying alphanumeric data with spatial references, as well as for producing maps. GIS are used for geomatics applications which process and distribute geographical information. Representations are usually in two dimensions, but 3-D rendering and animations can be developed in order to present time-based variations over a territory.


Quantum GIS, a GIS program published under a GPL license, is one of the official projects of the Open Source Geospatial (OSGeo) foundation. QGis runs under Linux, Unix, Mac OS X, and Windows. It handles various vector- and raster-based formats and supports the features and formats of several databases.


This is a GIS developed by GeoConcept SA. We generally use this tool to track transportation of materials over long distances. It manages alarms triggered by prolonged stops or divergence from a theoretical itinerary.
