Orthophotography within the Porirua City urban area in the Porirua City District totalling approximately 139 km2. The area of capture is located within the Wellington Region of the North Island, and captured in the flying seasons (summer period) 2019-2020.
Imagery was captured for Porirua City Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand.
Data comprises: • 1,667 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 supplied tile layout shape file for specific details, naming conventions, etc.
Imagery supplied as 10cm pixel resolution (0.15m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 m @ 95% confidence level.
