Project Aerial photography was captured over the Canterbury Region rural areas covering Waimakariri and Selwyn Districts, Christchurch City and Banks Peninsula, totalling approximately 5,537 km2. The area of capture covers part of the Canterbury Region situated on the east coast of the South Island.
Data Acquisition Aerial photography was captured using Vexcel's digital UCE camera during the 2018/2019 flying season (September 2018 – 30 March 2019) and extended to 12 May 2019.
Captured on the following dates 9 February 2019, 17 and 19 April 2019 and 1 May 2019.
Camera and Flying Height For this project two cameras were used as follows: Photography captured using Vexcel's digital UCE camera fitted with the 100 mm lens and flown at an altitude of approximately 18,928 ft (5,769 m) with the lowest ground GSD set at 0.3 m. Photography captured using Vexcel's digital UCE camera fitted with the 80 mm lens and flown at an altitude of approximately 16,580 ft (5,053 m) with the lowest ground GSD set at 0.3 m
Sun Angle Imagery captured with a minimum sun angle of 35 degrees. Towards the end of the season the sun angle was lowered to a minimum of 30 degrees, except Waimakariri District that remained at +35 degrees. Imagery captured with a sun angle between 30.0 and 70.1 degrees.
