“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!”
For those who aren’t familiar with Orfeo ToolBox or OTB, it’s a powerful open-source remote sensing library that allows you to manipulate and process remote sensing (RS) data in several ways. If you’re interested to learn what remote sensing applications OTB has to offer, the OTB CookBook is a good place to start. OTB is cross-platform and works in Linux, macOS, Windows and is a great choice if you’re looking for an application to add to your RS toolkit.
OTB’s algorithms can be accessed from a variety of sources: in Monteverdi, in Python, from the command line, in C++, and even in QGIS. To access OTB’s algorithms in QGIS, we need to activate OTB as a Provider under the Processing Options.
Upon successfully adding OTB as a processing provider, you should now be able to find and run OTB algorithms in QGIS either from the Processing Toolbox or searching for them using the Locator.
And that’s how you add Orfeo ToolBox as a processing provider in QGIS.
