Toitū Te Whenua Land Information New Zealand

2023

Orthophotography within the Queenstown Lakes Region captured in the flying season of 2022-2023. Coverage encompasses Wanaka, Hawea and Luggate.

Imagery was captured for Queenstown Lakes District Council by Landpro Ltd, 13 Pinot Noir Drive, Cromwell 9310, New Zealand.

Data comprises:
• 166 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 10cm pixel resolution (0.1m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.3m at 95% confidence level in clear flat areas.

Index tiles for this dataset are available as layer [Queenstown Lakes 0.1m Urban Aerial Photos Index Tiles (2022-2023)](http://data.linz.govt.nz/layer/112780)

The camera

Imagery for this schedule was acquired using the Leica RCD30.


Capture Dates
Imagery was acquired on the 7th and 8th of December 2022 and the 26th of January 2023.

Orthophoto rectification procedure
The imagery was developed into tiffs using Leica Frame Pro. The exterior orientation
was obtained by using IPAS CO+, which uses the trajectory and event file to
determine an accurate orientation of every image.
The imagery was then run using Pix4D. Keypoints were computed on the images
and matches were then determined. From these matches, Automatic Aerial
Triangulation (AAT) was run. This results in the creation of an Orthomosaic based on
orthorectification.
