This paper demonstrates magnitude of the systematic distortions of horizontal control net when the geoid is neglected in projection computation to a reference ellipsoid. To see the geoid negligence effects, two adjustments are carried out with/without geoid information for the north-east portion of Japanese trilatelation network. The geoid reported by R. H. RAPP is used for the projection computation. Results of a comparison of those adjustments as well as the NNSS and conventional positions are described. It is concluded that the geoid undulation should not be neglected in trilatelation adjustments. A large local rotation of HOKKAIDO district in the conventional net is found.
