Magnetic, radiometric, electromagnetic and near-infrared profiling with an ultralight airborne platform

Over the past three years the Geophysics Division and co-workers have developed an<br>ultra light airborne mapping facility. It consists of a Streak Shadow ultralight aircraft which<br>records the following data sets namely a) total field magnetic, b) 512 channel gamma-ray<br>spectrometric, c) pulsed, wide-band time domain electromagnetic, and d) 512 channel near<br>infra-red reflected light.<br>The purpose of this facility is to geophysically map areas identified for exploration,<br>mapping or environmental monitoring, in unprecedented detail, much more cost effectively<br>than ground surveys or helicopter borne surveys. Routine survey specifications for the<br>Streak Shadow are 50m flight line spacing, flying 50m above surface (terrain and weather<br>conditions permitting).
