This Imagery was commissioned by LINZ on behalf of GNS science, Environment Canterbury Regional Council, Marlborough District Council, Kaikoura District Council and Hurunui District Council for earthquake recovery purposes. It was captured by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand.
The area of capture is located in the Marlborough and Canterbury Regions of the South Island totalling approximately 10,466 km2.
Data Comprises: • 1648 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:5,000 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 for specific details, naming conventions, etc.
Imagery supplied as 30cm pixel resolution (0.3m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±2 m (@ 95% confidence).
Index tiles for this dataset are available as layer [Kaikoura 0.30m Rural Aerial Photos Index Tiles (2016-2017)](http://data.linz.govt.nz/layer/95444).
