A new multi-scale measure for analysing animal movement data

► We introduce a new multiscale measure (MSSI) for analysing animal tracking data. ► MSSI is a generalisation of 'Straightness Index' over all possible temporal scales. ► One major advantage of MSSI is the simplicity of its computation. ► We demonstrate the use of MSSI on synthetic and real animal movement data. ► MSSI provides information about behaviour over multiple spatio-temporal scales.
