Orthophotography within the Taranaki Region captured in January 2022. Coverage encompasses New Plymouth, Inglewood, Lepperton, Ōkato, Tongapōrutu, Urenui, Hāwera, Normanby, Okaiawa, Manaia, and Kupe.

Imagery was captured for Taranaki Regional Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.

Data comprises:
• 2982 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. Please refer to the tile index layer for specific details, naming conventions, etc.

Imagery supplied as 10cm pixel resolution (0.1m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 at 95% confidence level in clear flat areas.
