The Effect of Topographic Correction on SPOT6 Land Cover Classification in Water Catchment Areas in Bandung Basin, Indonesia

Currently, there is no generally accepted topographic correction method to be applied in different landscape contexts. This study derived land cover maps in Ci Kapundung and Ci Sangkuy upper water catchment areas, which are located in a rugged terrain in mountainous areas in Bandung Basin, Indonesia, using object-based classification of satellite images. Under these conditions, a modified sun-canopy-sensor correction (SCS+C) was chosen as topographic correction method. Its performance was evaluated using Overall Accuracy (OA) method. Result shows that the correction method could improve the accuracies to 77% and 87.58% for the first and second case studies respectively.
