Abstract

GPS is regularly used by movement ecologists to track animals, whose data are used to infer aspects of animals' behaviour and the factors that might drive this. Temporal signatures of the occupancy of places helps us understand animals' use of space, but this can hard to explore because of the complex spatiotemporal nature of the data. We present visual encodings and interactions designed to identify how temporal occupancy signatures of places vary spatially. These tile the space into grid squares, embedding temporal glyphs within. We apply these to GPS data from gull tracking and illustrate their use in movement ecology. The tool that implements this and data are available to download and use.
