The purpose of this presentation is to present a Case Study of using QGIS and OTB (Orfeo Tool Box) for land use mapping – Feedback from Burkina Faso.
In the framework of Second National Forest Inventory (NFI2), The Government of Burkina Faso in collaboration with the Grand – Duchy of Luxembourg, proceed to the producing of a new Land Cover database of Burkina Faso so called ‘Base de données d’Occupation des Terres Spécifiques’ (BDOTS).
This database includes 14 land cover/land use classes and has been carried out from a national coverage of RapidEye satellite images (84 scenes). The surface area of the minimal mapping unit mapped in the project is, 0.25 ha. The mapping method is based on a supervised classification SVM (Suport Vector Machine) using QGIS 2.2 OTB and SAGA to the vector component.
