Christchurch City Data

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

Orthophotography for urban areas across Christchurch City totalling approximately 524 km2. Taken in the flying season (summer period) 2018-19. The area of capture is located in the Canterbury Region of the South Island.

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

Data comprises:
• 7984 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 for specific details, naming conventions, etc.

Imagery supplied as 7.5 cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.15 m @ 95% confidence level.
