Selwyn 0.075m Urban Aerial Photos (2019)

Orthophotography captured over three urban areas within the Canterbury Region totalling approximately 36km2. The areas of capture cover Prebbleton, Kirwee, and Arthur's Pass in the Selwyn District.


Imagery was captured for Environment Canterbury by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.


Data comprises:

• 516 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 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15m at 68% confidence level in clear flat areas.


Index tiles for this dataset are available as layer [Selwyn 0.075m Urban Aerial Photos Index Tiles (2019)]( http://data.linz.govt.nz/layer/106499 )
