Abstract
Survey of Israel is re-mapping an area of 1,600 square kilometers in southern Israel, using 1:40,000 scale aerial photographs. In this area only a few 3D national control points were available, and no reliable geoidal model could be applied. An attempt was made therefore to determine whether GPS could provide a satisfactory geodetic control, including determination of orthometric heights. The approach was based on measurement of the geoid slope between two successive points and conversion of the differential ellipsoidal heights (GPS) to differential orthometric heights. The method is simple and cost effective. The results indicate that the method may be used in cases where no undulation model is available and the needed height accuracy is decimeter level.
