Auckland 0.075m Rural Aerial Photos Index Tiles (2020)
Index Tiles ONLY, for actual orthophotos see layer [Auckland 0.075m Rural Aerial Photos (2020)]( http://data.linz.govt.nz/layer/107219 )
Orthophotography within the Auckland Region captured in March and December 2020. Coverage encompasses Rodney, Hunua Ranges, Clevedon, Great Barrier and outer islands, and east Waiheke island.
Imagery was captured for Auckland Council by AAM NZ Ltd, 6 Ossian St, Napier, New Zealand.
Data comprises:
• 6593 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.
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.

Ground Support:
GPS base station support was sourced from continuously operating reference stations in and around the project area. Ground control points were existing field survey by Opus International Consultants. Surveys were conducted between 19 November 2015 and 13 May 2016.
Image Processing Workflow:
- Flight planning
- Aerial image acquisition
- Imagery download and inspection
- Combine and index imagery with post-processed GPS
- Aerial triangulation and adjustment to ground control
- Preparation of Client DTM
- Vector Mapping if required – (not required for this project)
- Editing or validation of DTM
- Orthophoto creation
- Image tiling
- Colour profiling
- Quality assurance
Block adjustment and orthorectification of the imagery was carried out using Visionmap and OrthoVista software.
Project specifications and technical processes were designed to achieve data accuracies as follows:
- Orthophotos: +/- 0.15m (Basis of estimation: Project design)
- Control: +/- 0.05m (Basis of estimation: Survey methodology used)
