Document Type and Number:

WIPO Patent Application WO/2024/004649

Kind Code:

A1

Abstract:

A first layer tidal current data acquiring unit (110a) acquires first layer tidal current data (210) representing an in-plane distribution, in a first layer, of a first layer vector quantity representing a direction and speed of a tidal current in the first layer. A second layer tidal current data acquiring unit (110b) acquires second layer tidal current data (220) representing an in-plane distribution, in a second layer, of a second layer vector quantity representing the direction and speed of the tidal current in the second layer. An inter-layer tidal current difference calculating unit (110f) uses the first layer tidal current data (210) and the second layer tidal current data (220) to calculate inter-layer tidal current difference data (290) representing an in-plane distribution of a difference vector quantity, which is a difference between the first layer vector quantity and the second layer vector quantity. A display control unit (110g) performs inter-layer tidal current difference display control to cause an inter-layer tidal current difference distribution map, obtained by visualizing the in-plane distribution of the difference vector quantity represented by the inter-layer tidal current difference data (290), to be displayed overlaid on a map.
