Using Google Maps and spherical quadrilateral approach method for land area measurement

摘要

In this paper, we present how to determine the land area measurement by using spherical quadrilateral approach method. The proposed method is compared to quadrilateral approach method with the UTM (Universal Transverse Mercator) coordinate system. The spherical quadrilateral approach method delivers in the calculation of the area of DIY and Central Java provinces 3328.2355 km
