Hungry cattle from space

Integrating animal GPS movement data with satellite imagery is a great way to visualise an animal’s interaction with its environment. This animation shows GPS points from three collared cattle moving over a farm grazing camp. The animals are herded in thin grazing strips each day using electric fencing. With an NDVI (normalised difference vegetation index) overlay from Landsat and Sentinel satellite imagery you can see the impact they have on the vegetation. Like lawn mowers they sequentially demolish the small strips of grass one day at a time.
