Radar images of dairy pasture on two different days

Note: Click the image below to view a larger version.

Remote sensing scientists use the TerraSAR-X radar satellite and computer-adapted colour-coded images to determine pasture biomass levels. The left-hand image is annotated with paddock names, while the numbers on the right-hand image represent grass height (cm). The darker shades represent longer grass. A dark strip in paddock N-2 in the right-hand image would have been caused by an electric fence preventing the cows from eating it.

This is different from our November 2013 survey, so even if you took part in that survey, we would appreciate you taking this survey as well.
