Descripción
The Land Cover Atlas of Sudan provides information on the land cover distribution by administrative divisions. The dataset has been created using the FAO/GLCN methodology and tools. Main data sources include high resolution satellite imagery from SPOT, Landsat, IRS (Indian Satellite), Aster, existing Africover land cover database and ancillary data. The legend was prepared using the Land Cover Classification System (LCCS): a comprehensive, standardized a priori classification system, designed to meet specific user requirements and created for mapping exercises, independent of the scale or means used to map. The classification uses a set of independent diagnostic criteria that allows the correlation with existing classifications and legends. Satellite images of Sudan were segmented into homogeneous polygons and they were interpreted according to the FAO/GLCN methodology for the production of a seamless and detailed land cover dataset for the whole country. Field verification was complet ed by national experts who received a customized training on methodology and tools. The final land cover product has around 490,000 polygons, classified into 83 different classes and eventually aggregated into 7 major classes for ease of analysis and display. The Land Cover Atlas is organized into two main sections: country and states. Each section provides information on the distribution of aggregated land cover as map and table. These products provide the user with valuable information on the availability and distribution of land resources through a multifaceted approach.
