Developing the standard operating procedures of ellipsoidally referenced surveys at coastal waters in Japan: trials of bathymetric data processing and verification of their results†
In recent years, with the spread and improvement in the accuracy of kinematic GNSS positioning, ellipsoidally referenced surveys （ERS） have become practically possible, which in principle do not require tide observations during the bathymetric surveys. In this paper, as the first step of a trial to establish the standard operating procedures for ERS in Japan, we presented the practical operating procedures of bathymetric data processing in ERS and vertical datum model estimation, by using the existing bathymetric data in Tokyo Bay. In this case, the validity of the ERS operating procedures was verified by comparing the depths in the ERS procedures with those in the conventional procedures with tidal reduction.
