OTB Orfeo Toolbox

pipeline status coverage status

Open Source processing of remote sensing images

Orfeo ToolBox (OTB) is an open-source project for state-of-the-art remote sensing. 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!

All of OTB's algorithms are accessible from Monteverdi, QGIS, Python, the command line or C++. Monteverdi is an easy to use visualization tool with an emphasis on hardware accelerated rendering for high resolution imagery (optical and SAR). With it, end-users can visualize huge raw imagery products and access all of the applications in the toolbox. From resource limited laptops to high performance MPI clusters, OTB is available on Windows, Linux and Mac. It is community driven, extensible and heavily documented. Orfeo ToolBox is not a black box!



We provide ready-to-use packages for Windows, Mac and Linux. Download them here on our website, and see instructions for your platform here in the Cookbook.

If you're interested, you can also compile from source.
