Reeves RR, Sanders F. 2019. 2019 thermal infrared survey of the Waiotapu Geothermal Field. Lower Hutt (NZ): GNS Science. 22 p. (GNS Science report; 2019/57). doi:10.21420/ZD6D-GD88.
An aerial thermal infrared (TIR) survey of the Waiotapu Geothermal Field was undertaken on 13 April 2019. Approximately 2260 TIR images were processed and mosaicked to produce a single, 16-bit image with a ground pixel size of approximately 2 m x 2 m (Figure A.1). The purpose of this report is to summarise the method of data collection and present the final TIR image and accompanying brief interpretation. The TIR data is of good quality and enables numerous geothermal and non-geothermal surface features to be identified and mapped to relatively high spatial accuracies (<3 m) within the limitations of the survey. The locations of TIR anomalies interpreted to be caused by geothermal activity are in general agreement with areas of known surface geothermal activity. (auth)
