OTB in Quantum GIS
Quantum GIS (often abbreviated to QGIS) is a free software desktop Geographic Information Systems (GIS) application that provides data viewing, editing, and analysis capabilities.
QGIS has been designed with a plugin architecture. This allows new features/functions to be easily added to the application. Many of the features in QGIS are actually implemented as core or external plugins.
OTB functionalities are available in QGIS through the Sextante plugin. Sextante provides access to a huge number of processing modules, and acts as a geoprocessing environment that can be used to call native and third-party algorithms from QGIS.
