Track Segmentation: Stops and Movements
This R script inputs animal tracking data and segments the time series for each individual animal into sequential periods of stops and movements. The algorithm identifies stops based on two influential user-defined thresholds: 1) a distance threshold (hereafter 'Dist') that defines the upper limit of spatial displacement permissible while occupying a stop, and 2) a duration threshold (hereafter 'Dur') that defines the minimum amount of time a stop is required to persist. Values for the Dist and Dur should be chosen in a manner that targets animal behavior(s) of interest while also accommodating the spatial accuracy and temporal frequency of the location data under analysis. Locations not classified as stops are classified as movements. A "User Guide" is included in the software package.
