Palmerston North 0.125m Urban Aerial Photos (2016-2017)

LINZ - Land Information New Zealand

2018

Orthophotography of Palmerston North City taken in the flying seasons (summer period) 2016-2017.

Imagery was captured for Palmerston North City Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand.

Data comprises:
•1,046 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:1,000 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 supplied tile layout shape file for specific details, naming conventions, etc.

Imagery supplied as 12.5cm pixel resolution (0.125m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.2 m @ 68% confidence level.

Index tiles for this dataset are available as layer [Palmerston North 0.125m Urban Aerial Photos Index Tiles (2016-2017)](http://data.linz.govt.nz/layer/99192)

Project
Aerial photography was captured over the Palmerston North urban area in the Manawatu and
Palmerston North City Districts totalling approximately 183 km2. The area of capture is located in the
Manawatu-Whanganui Region of the North Island.

Data Acquisition
The aerial photography for this project was captured within the 2016/17 flying season (September
2016 – April 2017) on the following dates:
1 March and 9-10 April 2017

Camera
All photography was captured using Vexcel's digital UCE camera and flown at:
0.125 m GSD: 7887 ft (2403 m) flying height
Camera Lens: 100 mm

Sun Angle
Imagery was captured with a sun angle between 38.9 and 50.5 degrees

Flight Planning
SN13884 Palmerston North Urban: 15 runs, 374 frames
Stereo capture: Forward overlap 60%. Side overlap 35%
SN13884 Palmerston North CBD: 3 runs, 21 frames
Stereo capture: Forward overlap 80%. Side overlap 80%

Urban Building Displacement Specification
Urban 0.125 m GSD imagery – using the UCE camera and by flying with 60% forward overlap and with
35% sidelap (standard stereo coverage), maximum 1.0 m building lean per 3 m height within the
image model area.
CBD 0.125 m GSD imagery – using the UCE camera and by flying with 80% forward overlap and with
80% sidelap near true ortho imagery as been achieved (near to no building lean).
