Behaviours are coded right with the data, and performances are better QGIS es un software GIS de escritorio de cdigo abierto que posibilita la gestin, el anlisis, la edicin y la visualizacin de datos.

Clarkes (1986) defined it as a computer-aided system for capturing, storing.

This definition is essentially referring to the Planck relation ( Ehf) equation that was defined by Max Planck. When fulfilling a specific need, we can delegate a lot of domain-specific data processing to the database : According to Marble (1983), a GIS is A system for collecting spatial data. The definition of quantum from is the smallest quantity of radiant energy, equal to Planck’s constant times the frequency of the associated radiation.

QGIS is perfectly integrated with PostGIS, a spatial database allowing to embed numerous processing capabilities and GIS features. It is possible to adapt the graphical user interface ( menus, toolboxes, docks…), extend behaviours through various mechanisms, and create specific custom features with plugins and new processing algorithms. QGIS is an application which can be highly customized, thanks to its plugin system.
