 Welcome to OTB CookBook's documentation!
 ========================================
 
-`Orfeo ToolBox (OTB) <http://orfeo-toolbox.org>`_ 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 its graphical interface called
-Monteverdi, from QGIS, Python, the command line or C++. Monteverdi is an easy to
-use, hardware accelerated visualization tool for satellite images in sensor
-geometry. 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 clusters, OTB is available on Windows, Linux and
-Mac. It is community driven, extensible and heavily documented.
-Orfeo ToolBox is not a black box!
