4 General requirements

4.1 Purpose of investigation Implement single-beam bathymetry according to mission requirements, obtain seafloor depth data, and conduct data analysis and correction through correction and correction of survey data. Process and map, compile bathymetric maps and seabed topographic maps of the survey area. 4.2 Adoption of benchmarks 4.2.1 Coordinate system When connecting, a conversion relationship with CGCS2000 should be established. 4.2.2 Height reference The 1985 national elevation datum is adopted. For distant seas and polar regions, mean sea level can be used as the elevation datum. 4.2.3 Depth benchmark The theoretical lowest tide level is used. When using other depth benchmarks, a conversion relationship should be established with the theoretical lowest tide level. ......
