A first layer tidal current data acquirer acquires first layer tidal current data that represent a first layer vector quantity representing a direction and a speed of a tidal current in a first layer. A second layer tidal current data acquirer acquires second layer tidal current data that represent a second layer vector quantity representing a direction and a speed of a tidal current in a second layer. An inter-layer tidal current difference calculator calculates inter-layer tidal current difference data that represent an in-plane distribution of a difference vector quantity being a difference between the first layer vector quantity and the second layer vector quantity. A display controller performs inter-layer tidal current difference display control for displaying, over a map, an inter-layer tidal current difference distribution map that visualizes the in-plane distribution of the difference vector quantity represented by the inter-layer tidal current difference data.

A data distribution device distributes a plurality of sets of data to a user one set of data at a time intermittently at intervals. Every time derived data obtained using the data are generated by the user, a registration device for user registers derived data generation history information indicating that the derived data are generated in a history management database. A derived data generation history information monitor examines whether or not derived data generation history information is registered in the history management database at a predetermined timing and, when no derived data generation history information is registered, suspends subsequent distribution of the data from the data distributor to the user.
