Index Tiles ONLY, for actual orthophotos see layer Christchurch 0.075m Urban Aerial Photos (2018)

Orthophotography over Christchurch CBD.
The aerial photography was captured on 14 January 2018.

Imagery was captured for the ‘Christchurch City Council’ by AAM NZ Limited, 6 Ossian St, NAPIER, New Zealand.

Data comprises:
•98 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:500 tile layout
•Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. The products are tiled into NZTopo50 1:500 tiles. Please refer to the supplied tile layout shape file 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 ± 0.15m @ 90% confidence level.
