Drone captured 2.2 km2 georeferenced, temperature-calibrated thermal infrared orthophoto of geothermal area.
Calibrated thermal imagery provides an estimate of a total heat loss of 43 ± 12 MW for thermal lakes and streams in the survey area.
Drone captured a 3km2 aerial photo and digital elevation model (DEM) of the Waikite geothermal area.
This study demonstrates the capacity of drones to produce accurate thermal maps of large, inaccessible geothermal areas.
