A radar altimeter and Global Positioning System (GPS) equipped Cessna 182 high-wing aircraft flown at an average altitude of 61m above ground level and an average ground speed of 185 km/h was used as the sampling platform. Transect width, 200m on each side of the aircraft at survey altitude, was delineated by fibreglass rods attached to the aircraft wing struts. Positioning of the rods was determined as per Marsh and Sinclair (1989). Tape was not placed on the aircraft windows as experience has indicated that this can impair the observers transect scanning pattern.
