4 Classification and coding principles
4:1 Systematic
Aiming at the construction and management of port informatization and the construction and application of port spatial data, scientific research is carried out according to the characteristics of port geographical elements:
Scientifically and systematically classify to form a classification system with clear logic levels, reasonable structure and clear categories, which not only fully reflects the level of geographical elements of the port
structure, and correctly reflect the correlation between the geographical elements of the port:
4:2 Stability
The formulation of the classification and coding system is based on the most stable characteristics of each geographical element of the port, and reflects the attributes and requirements of the geographical elements of the port:
