Index Tiles ONLY, for actual orthophotos see layer Waikato District 0.1m Urban Aerial Photos (2014)

Orthophotograhpy was taken for the Waikato District between the 10th of January 2014 and the 7th of March 2014. Coverage encompasses the urban towns and settlements within the Waikato District Council area.

Towns and settlements include Raglan, Whatawhata, Te Kowhai, Tamahere, Matangi, Horotiu, Ngaruawahia, Taupiri, Gordonton, Glen Massey, Glen Afton/Pukemiro, Huntly, Ohinewai, Rangiriri, Te Kauwhata, Meremere, Onewhero, Port Waikato, Tuakau and Pokeno.

Imagery was captured for the Waikato District Council by NZ Aerial Mapping Ltd, 208 Warren Street, Po Box 6, Hastings, 4156, New Zealand

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

Imagery supplied as 10cm pixel resolution (0.1m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is +/-0.3m (@ 90% confidence).

The STI77-NZVD2016 grid enables the conversion of normal-orthometric heights from the Stewart Island 1977 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.

STI77-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Stewart Island 1977 vertical datum (167.2° E to 168.8° E, 46.5° S to 47.5° S).

The height conversion grid models the difference between the Stewart Island 1977 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of STI77-NZVD2016 is better than 18 centimetres (95% Confidence interval).

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