Orthophotography within the Otago Region taken in the flying seasons (summer periods) 2019-2021. Coverage is of the Otago region covering parts of Central Otago and Clutha Districts.
Imagery was captured for Otago Regional Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Rosedale,0632, New Zealand.
Data comprises: •2669 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:5,000 tile layout •Tile layout in NZTM projection containing relevant information.
The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. Please refer to the index tiles layer for specific details, naming conventions, etc.
Imagery supplied as 30 cm pixel resolution (0.30 m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.5 m @ 95% confidence level.
Index tiles for this dataset are available as layer [Otago 0.3m Rural Aerial Photos Index Tiles (2019-2021)](http://data.linz.govt.nz/layer/106404)
Project Aerial photography was captured over the Otago Region covering an area totalling approximately 21878 km2. The area of capture covers part of the Otago Region of the South Island.
Data Acquisition Aerial photography was captured using Vexcel's digital UCE during the 2019-2021 flying season.
Captured on the following dates 7 Feb 2019, 6 April 2019, 15 Dec 2020, 28 Dec 2020, 12 Jan 2021, 5 Feb 2021, 6 Feb 2021, 20 Feb 2021.
Camera Photography was captured using Vexcel's digital UCE camera fitted with the 100 mm lens and flown at an altitude of approximately 18928 ft (5,769 m) with the lowest ground GSD set at 0.30m. Some photography was also captured using UCE80 camera fitted with 80mm lens and flown at an altitude of approximately 15,781 ft with the lowest ground GSD set at 0.3m.
Sun Angle Imagery captured with a minimum sun angle of 40 degrees. The sun angle of the imagery used for the orthorectification ranged from 30 to 67.5 degrees.
Flight Planning The flight survey number for this project is SN142032 The flight plan is named 'Central Otago' comprising 89 runs, with 2038 frames in Central Otago District, and 1970 frames in Clutha DIstrict. All imagery captured in stereo: forward overlap 60%, min 54%; side overlap 35%, min 15%.
Environmental Specification Imagery captured with no cloud or cloud shadow within the area of interest. Imagery for all harbour, coastal and tidal areas acquired during low tide periods, being two hours either side of low tide.
