Georeferencing in remote sensing imagery provides an integrated validation on the land use land cover (LULC) changes of urban growth. Geometic accuracy in georeferencing can be increased using Global Positioning System (GPS) derived ground control points (GCPs). Providing higher geometric accuracy is essential in LULC analysis especially in densed area with rapid urbanization. The geometric accuracy relies largely on accurate rectification of the remotely sensed data to produces classified thematic change maps. The study used data from Landsat TM, ETM+ and OLI TIRS. The rectification process involves two main references which are the GPS derived GCPs and the topographic map derived GCPs. GPS derived GCPs are acquired through ground measurement using Android 10.36.0 WGS84 capability smartphone. The topographic map is acquired from the Department of Survey and Mapping Malaysia with 1:50,000 scale, 25-meter countour line and rectified skew orthomophic grid projection. The study found that the GPS-derived GCPs were accurately higher with the root mean square error (RMSe) shows higher accuracy for its source points and corrections points. © ACRS 2021.All right reserved.
