Abstract
An airborne video thermal infrared survey was conducted over the Taupo Industrial Area and Pony Club geothermal areas, east Taupo, on the night of 3 March 1999. Ground truth measurements obtained from both water features and ground surface and near-surface were used to calibrate and interpret the imagery. The temperature calibrated imagery agreed well with the ground surface measurements, and anomalous geothermal features above ambient were detected. A relationship between surface temperature and surface heat flow was derived and a heat flow map produced from a calibrated TIR image of the site. The heat flow from the anomalous geothermal areas at the site was found to be
