Orthophotography over Porirua City taken in the flying season (summer period) 2015 -16.

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

Data has subsequently been provided to LINZ and this comprises:
• 249 x 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. The products are tiled into NZTopo50 1:1,000 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 Generally +/-0.5m GSD (90% Confidence), but worse in hilly areas,
