Waitaki District Data

Orthophotography in the Otago region taken in the flying season (summer period) 2013 - 2014. Coverage encompassed the Waitaki council areas.

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

Data comprises:
•529 x ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:5,000 tile layout
•Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. The products are tiled into NZTopo50 1:5,000 tiles. Please refer to the supplied tile layout shape file for specific details, naming conventions, etc.

Imagery supplied as 40cm pixel resolution (0.4m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is +/-0.6m.

Index tiles for this dataset are available as layer Otago 0.4m Rural Aerial Photos Index Tiles (2013-14)

An artificial open waterway used for transportation, waterpower or irrigation.
