Advisian have found that Unmanned Aerial Vehicles (UAVs) provide a rapid approach to quickly map benthic habitat, mangroves and dredge plumes at comparatively minimal cost to traditional methods.
Advisians remote helicopter-based image capture system utilises a high resolution digital camera and integrated GPS/Inertial Navigation Unit (GPS/INU) to undertake mapping surveys. Advisian has designed methodologies using repeatable flight paths to validate against baseline imagery. Imagery is flown at set intervals, taking overlapping photos of the landscape below. Images are typically captured from 50-100 metres above sea-level.
