The Elephant Map
Elephants: Year in a Day shows the patterns of movement of five bull elephants in Laikipia County, Kenya.
This visualisation uses Google Maps with CartoDB's Torque library to animate 34,786 GPS positions. A year's worth of location data for the five elephants has been compressed into a single day on the map to illustrate the general pattern of movement of the bull elephants, regardless of season or individual.
The map also highlights local land use, displaying cultivated land and safe habitats through the use of colored polygon overlays. The land tract overlays help to highlight where the bull elephants have been accessing farmed land and raiding crops under the cover of darkness.
