Lake Rotoroa Data

Orthophotography for the Tasman region taken in the flying season (summer period) of 2016-2017. Covering the area centred primarily around Murchison.

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

Data has subsequently been provided to LINZ and this comprises:
• 338 x 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. The products are tiled into NZTopo50 1:5,000 tiles. Please refer to the supplied tile layout shape file 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 +/-1.2m @ 90% confidence level.

Index tiles for this dataset are available as layer Tasman 0.3m Rural Aerial Photos Index Tiles (2016-17)
