Mackenzie 0.075m Urban Aerial Photos Index Tiles (2020)
Index Tiles ONLY, for actual orthophotos see layer [Mackenzie 0.075m Urban Aerial Photos (2020)]( http://data.linz.govt.nz/layer/10687 5)
Orthophotography within the Canterbury Region captured in January and March 2020. Coverage encompasses Lake Tekapo and Regional Park, Burkes Pass, Kimbell and Fairlie, Ohau Canal and Twizel, and Albury.
Imagery was captured for Environment Canterbury by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.
Data comprises:
• 2818 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:500 tile layout
• Tile layout in NZTM projection containing relevant information.
The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection.
Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15m at 95% confidence level in clear flat areas.

Data Acquisition
The aerial photography for this project was captured within the 2019/20 flying season (September 2019 – April 2020).
Camera and Flying Height
All photography was captured using Vexcel's digital UCE camera fitted with the 100 mm lens. Urban areas flown at an altitude of approximately 4,732 ft (1,441 m) with the lowest ground GSD set at
0.075 m.
Capture Dates
The aerial imagery was captured on the following dates:
Lake Tekapo 01/03/2020
Burkes Pass 01/03/2020
Kimbell, Fairlie 01/03/2020
Ben Ohau, Twizel 19/01/2020
Albury 01/03/2020
Sun Angle
Imagery captured with a minimum sun angle of +45 degrees. The sun angle of the imagery used for the Timaru orthorectification ranged from 48.8 to 66.4 degrees.
Lake Tekapo 51.6-52.6
Burkes Pass 51-51.3
Kimbell, Fairlie 47.4-50.9
Ben Ohau, Twizel 60.5-65.9
Albury 46.3-46.8
Flight Planning
The flight survey number for this project is:
SN14089 Mackenzie Urban 7-5 cm UCE V2 comprising 33 runs, 738 frames
All urban 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.
Rivers captured at time of low river flow.
Urban Building Displacement Specification
Urban 0.075 m GSD imagery – using the UCE camera and by flying with 60% forward overlap and with 35% sidelap (standard stereo coverage), maximum 1.1 m building lean per 3 m height within the image model area.
Ground Control
A combination of existing control and LINZ benchmarks were used for aerial triangulation for this project
