-ORFEO Toolbox (OTB) is 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. Targeted algorithms for high
-resolution optical images (Pleiades, SPOT, QuickBird, WorldView, Landsat,
-Ikonos), hyperspectral sensors (Hyperion) or SAR (TerraSarX, ERS, Palsar) are
-available.

 OTB will be built with support for the following packages if they are
 available at compile time: numpy3.
