GPS Data Analysis System: Movements

subtitle Japanese

 The details of the methods will be made available after the relevant papers are published.

GAP Method

This method dichotomises a dataset based on the GAP value.

Angle Shorter-Side-Length Method

This method calculates the irregularity of a data point based on the position of its two neighbours.

Midpoint-Centroid Deviation method

This method calculates the irregularity of a data point based on the positions of its multiple neighbours.

Time-Space Neighbourhood Density (tsND) Method

This method visualises animal movements as a repetition of two contrasting phases.

Timeline segmentation based on tsND

The timeline is segmented into two contrasting movement phases: 'move-around'- and 'move-away' phases.

Dual-Anchor Method

This method uses two anchor points to show the location of a focal point.

Average Centroid Distance (ACD) Method

This method calculates the spatial scale of animal movement for a time span.
