An infrastructural problem often faced by ITB Ganesha Campus is waterlogging in certain areas after high intensity rain. This phenomenon has a negative impact on the infrastructure of the campus such as damage to the road which may cause the bond between the aggregate and asphalt to weaken (Nurhudayah, 2009). Digital Terrain Model (DTM) data is needed to simulate waterlogging. The primary data used in this study are LIDAR point cloud data, photogrammetric point cloud data, and terrestrial height data. Additional data used are precise undulation data of ITB Ganesha Campus and the Waterlogging that has occurred. Ground elevation data from terrestrial acquisition results are in the geoid vertical reference system, while LIDAR point cloud data and photogrammetric point cloud are in the vertical ellipsoid reference system. Therefore the equalization of vertical reference must be done using the precise undulation data of ITB Ganesha campus. The accurate geoid is obtained by GPS/levelling method.
