OTB Applications are now included in the ORFEO ToolBox repository (see https://www.openhub.net/p/otb)
This package includes a set of applications for remote sensing image processing such as orthorectification, classification, object extraction... Few of these applications come with a full GUI interface. Applications are based on the Orfeo Toolbox (OTB) library. More complex applications are now developed in the integrated application: Monteverdi.
OTB Applications is distributed under a free software licence CeCILL (similar to GPL) to encourage contribution from users and to promote reproducible research.
