The movement path of an animal, sampled periodically using GPS telemetry, offers rich information on animal behaviour. To facilitate greater use of these data, we outline four approaches to estimate the behavioural value of spatial locations based on movement data. These approaches include the assessment of the intensity of use (e.g. density isopleths), functional use (e.g. movement states), structural aspects of use (e.g. network graphs) and fitness values of locations (e.g. energetic maps) as detailed in table 1.
