Abstract: High quality aerial photos (orthophotos) and digital surface models (DSM) are invaluable at all phases of geothermal exploration and development including geological, geochemical and geophysical surveys, environmental baseline studies, geotechnical studies, civil works, steam field design, plant design and construction. High resolution ( less than 0.1m) imagery and data are typically collected by sensors mounted on board manned light aircraft. Lower resolution imagery ( more than 0.5m) can be obtained from satellite imagery. A rapidly improving alternative is the collection of imagery from sensors mounted on unmanned aerial vehicles (UAVs). Such imagery can be used to produce high resolution ( less than 0.1m) orthophotos, or DSM
