Abstract
A velocity feature-vector data acquirer (225) acquires velocity feature vector data (SVF) containing detected velocity data (SV) indicating a chronological series of velocities of a fishing craft and velocity dispersion data (SVb) indicating a chronological series of dispersions of the velocities of the fishing craft. An activity estimator (241) executes, based on the velocity feature vector data (SVF), an activity identifying process for identifying whether the fishing craft is during travel or fishing operation, and outputs activity identification result data (AD) indicating a chronological series of identification results in the activity identifying process.
