Orfeo ToolBox (OTB) is an open-source project for state-of-the-art remote sensing. It is developped by CNES in the frame of the ORFEO program.Built on the shoulders of the open-source geospatial community, it can process high resolution optical, multispectral and radar images at the terabyte scale. A wide variety of applications are available: from ortho-rectification or pansharpening, all the way to classification, SAR processing, and much more!
