Evaluation of multi-scale representation of ocean flow fields using the Euler method based on map load

ABSTRACT

This paper takes the map load as the evaluation indicator for multi-scale representations of ocean flow fields using Euler method. First, the map load of the ocean flow fields is calculated and the suitable map load interval is analysed in order to obtain the key scale for the multi-scale representation of ocean flow fields. Then, the load is limited by appropriate load intervals to fit the relationship between map load and scale. Finally, a mathematical model for multilevel comprehensive evaluation in fuzzy mathematics is established, and the usability of the resulting ocean flow field map is evaluated using questionnaires.
