--- Removed the GPS level of the relevant content (1998 version 7.5);

--- Added GNSS level measurements (see 7.5);

--- Modify the navigation and positioning of the general provisions of the microwave ranging and GPS ranging to GNSS and polar coordinates positioning Act, the control point selection requirements have been changed (see 8.1, 1998 version 8.1);

--- Remove the microwave ranging positioning system positioning, GPS positioning (1998 version of 8.2, 8.3);

--- Added GNSS positioning, polar positioning, underwater acoustic positioning, navigation software (see 8.2, 8.3, 8.4, 8.5);

--- Modify the measurement requirements of working level in depth measurement (see 9.1.6.3, 1998 version 9.1.6.3);

--- Increased use of GNSS tide survey water depth technical requirements (see 9.1.10);

--- Modify the technical requirements for depth measurement (see 9.2, 1998 version 9.2);

--- Modify the sounding positioning technical requirements (see 9.3, 1998 version 9.3);

--- Increasing the requirements of the analog records for inspection and finishing (see 9.5.4.1);

--- Increasing the technical requirements for draft correction (see 9.5.5.1);

--- Modify the technical requirements for dynamic draft correction (see 9.5.4.3, 1998 version 9.5.5.3);

--- Modify the production of the topographic map, the drawing of the water depth map to the topographic map production (see 9.6,1998 version 9.6);

--- Removed the production of the original measurement (1998 version 9.7);

--- Modify the requirements of computer-aided mapping (see 9.7, 1998 version 9.8);

--- Modify the general provisions of coastal topography (see 10.1.1, 1998 edition 10.1);

--- Modify the coastal topographic survey in the Ministry of debris measurement method, instead of using the total station polar coordinate method, the global navigation satellite system real-time motion State measurements, continuous operation of the base station network method for measurement (see 10.2, 1998 version 10.2);

--- Increased the definition of the coastline (see 10.3.1);

--- Modify the coastline measurements, the specific requirements of dry beach measurements (see 10.3, 10.4, 1998 version 10.3, 10.4);

--- Modify the technical design of seafloor scanning, implementation, the contents of information (see 11.2,11.3,11.4,1998 version 11.2, 11.3, 11.4);

--- Modify the inspection and acceptance, the results of the relevant content (see Chapter 12, Chapter 13, 1998 version 12.1,12.2,12.3);

--- Modify the sea level leveling joint calculation formula (see Appendix A, 1998 edition of Appendix A);

--- Modify the water level observation of a good date selection formula (see Appendix B, 1998 version of Appendix B);

--- Modify the average sea level and depth of the reference plane to determine the formula (see Appendix C, 1998 version of Appendix C);

--- Modify the sound velocity correction formula (see Appendix D, 1998 edition of Appendix D).
