distributed as an open source library of image processing algorithms. OTB is based on the medical image processing library ITK and offers particular functionalities for remote sensing image processing in general and for high
spatial resolution images in particular. OTB is distributed under the permissive open source license Apache v2.0 - aka Apache Software License (ASL) v2.0. The library is intensively tested on several platforms as Linux, Unix and Windows. Most functionnalies are also adapted to process huge images using streaming and multithreading as often as possible.
