• In the Earth sciences sector, sensors for measuring properties of the Earth are rapidly becoming adapted for drone use now that new developments in technology have led to an increase in the size and payload of unmanned aerial vehicles (UAVs or ‘drones’). This article presents two studies that explore the opportunities for adding a gamma-ray spectrometer to a drone in order to map the texture or contamination of soil.

  • Over three decades of development have streamlined functionality and increased the accuracy of yield mapping technology. This has led to greater on-farm adoption of the hardware itself, as well as precision-agriculture systems more generally.
