This dataset was first added to LINZ Data Service on 25 Oct 2019.

Orthophotography within the Otago Region taken in the flying seasons (summer period) 2018-2019. Coverage encompassed the urban areas within the Dunedin City District.

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

Data comprises:
•1,372 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:1,000 tile layout
•Tile layout in NZTM projection containing relevant information.

The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. Please refer to the supplied tile layout shape file for specific details, naming conventions, etc.

Imagery supplied as 10cm pixel resolution (0.10m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.2 m @ 95% confidence level.

Index tiles for this dataset are available as layer Dunedin 0.1m Urban Aerial Photos Index Tiles (2018-2019)

This dataset was first added to LINZ Data Service on 07 Oct 2019.

The Dunedin-Bluff 1960 to NZVD2016 Conversion Raster provides users with a two arc-minute (approximately 3.6 kilometres) raster image of the conversion of normal-orthometric heights from the Dunedin-Bluff 1960 local vertical datum to the New Zealand Vertical Datum 2016 (NZVD2016).

The conversion value is represented by the attribute “O”, in metres.
This conversion and NZVD2016 are formally defined in the LINZ standard LINZS25009.

The height conversion grid models the difference between the Dunedin-Bluff 1960 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy is better than 2 centimetres (95% Confidence interval).

More information on converting heights between vertical datums can be found on the LINZ website.
