This study was carried out in White Nile state to evaluate and tested the accuracy assessment (data quality) to monitor and assess the land cover land use mapping: The accuracy assessment model was used to measure of how many ground truth pixels are correctly classified. To achieve this objective sample points are located by Geographic Positioning System (GPS). Where, Landsat satellite imagery (ETM) year 2010 represented same results with the GPS and Geographic Information System (GIS). The result displayed an accuracy of 94.04 % with over all Kappa statistics (ka) of 91.26 %, however Remote sensing data, GPS data (ground truth), positional accuracy, logical consistency matching with the information on the map.
