Selwyn District Data

Index Tiles ONLY, for actual orthophotos see layer Selwyn 0.075m Urban Aerial Photos (2018-2019)

Orthophotography within the Selwyn District taken in the flying seasons (summer period) 2018-2019. Coverage encompasses urban areas totalling approximately 318 km2.

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

Data comprises:
• 3,688 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 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is:
• ±0.15 m @ 95% confidence level in clear open spaces (2 sigma) over area of interest
• ±0.15 m @ 68% confidence level in clear open spaces (1 sigma) over peripheral imagery
