Abstract
This study aims to investigate the variation accuracy of WorldView-2 HD 15 cm satellite imagery orthorectified using the Rational Polynomial Coefficients from Ground Control Points method in four types of areas: flat, undulating, homogeneous, and heterogeneous in Cirebon City West Java. The methodology used includes image preprocessing, orthorectification performed with distributed ground control points and supported by national digital elevation model (DEMNAS) data, and accuracy evaluation. Accuracy evaluation is carried out by comparing orthorectified imagery with RTK GNSS field measurements, focusing on point positions as independent control point (ICP) assessed using the Root Mean Square Error (RMSE). The results show for the flat area the accuracy can meet the standard at 1:1.000 scale on level 3 and for all type of area in study area the accuracy can meet the standard at 1:5,000 scale on level 1.
