Nelson 0.075m Urban Aerial Photos (2022)
Orthophotography within the Nelson Region captured in January 2022. Coverage encompasses urban areas within the Nelson City District.
Imagery was captured for Nelson City Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.
Data comprises:
• 997 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:1000 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 tile index layer for specific details, naming conventions, etc.
Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 at 95% confidence level in clear flat areas.
Index tiles for this dataset are available as layer [Nelson 0.075m Urban Aerial Photos Index Tiles (2022)](http://data.linz.govt.nz/layer/109701)

dataset
dataset
The aerial photography for this project was captured within the 2021/22 flying season (September 2021 – April 2022).
Camera and Flying Height
All photography was captured using Vexcel's digital UCE camera fitted with the 100 mm lens and flown at an altitude of approximately 4,773 ft (1,454 m) with the lowest ground GSD set at 0.075 m.
Capture Dates
The aerial imagery was captured on the following dates:
15-16 January 2022.
Sun Angle
Imagery captured with a minimum sun angle of +35 degrees. The sun angle of the imagery used for the orthorectification ranged from 38.5 to 68.3 degrees.
Flight Planning
The flight survey number for this project is SN14226
The flight plan is named ‘Nelson Urban 21-24 7-5cm UCE’ and comprises 57 runs, 2,718 frames. 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. Tidal areas captured
-/+ 1.5 hours either side of low tide.
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) will achieve ~1 m building lean per 3 m height in the corners of the imagery used. Tall structures inwards of the corner of the frame will have less lean the closer to the nadir they are.
Ground Control
A combination of existing control and LINZ benchmarks were used for aerial triangulation for this
project
