Otago Region Data - Page 13

This layer contains the DSM for LiDAR data in the Otago Region, north of Lake Wakatipu and surrounding Queenstown and Arrowtown, captured in 2021.

• The DEM is available as layer Otago - Queenstown LiDAR 1m DEM (2021).

• The index tiles are available as layer Otago - Queenstown LiDAR Index Tiles (2021).

• The LAS point cloud and vendor project reports are available from OpenTopography.

LiDAR was captured for the Queenstown Lakes District Council by Landpro on the 13th and 14th of March 2021. These datasets were generated by Landpro Ltd and their subcontractors. Data management and distribution is by Toitū Te Whenua Land Information New Zealand.

Data comprises:

• DEM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout

• DSM: tif or asc tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout

• Point cloud: las tiles in NZTM2000 projection, tiled into a 1:1,000 tile layout

Pulse density specification is at a minimum of >4 pulses/square metre.

Vertical accuracy specification is +/- 0.2 m (95%).

Horizontal accuracy specification is +/- 1.0 m (95%).

Vertical datum is NZVD2016.

The DUN58-NZVD2016 grid enables the conversion of normal-orthometric heights from the Dunedin 1958 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.

DUN58-NZVD2016 is published on a two arc-minute grid (approximately 3.6 kilometres) extending over the benchmarks that nominally define the extent of the Dunedin 1958 vertical datum (168.4° E to 171.3° E, 43.9° S to 46.5° S).

The height conversion grid models the difference between the Dunedin 1958 vertical datum and NZVD2016 using the LINZ GPS-levelling marks. From the GPS-levelling marks the expected accuracy of DUN58-NZVD2016 is better than 2 centimetres (95% Confidence interval).

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

Orthophotography for the Southland & Central Otago regions taken in the flying season (summer period) 2013 - 2014. Coverage encompassed parts of the Environment Southland, Southland District, Invercargill City, Clutha District, Gore District and Central Otago District council areas.

Imagery was captured for ‘Environment Southland, Southland District, Invercargill City, Clutha District, Gore District, Central Otago District councils, Land Information NewZealand, Ministry for Primary Industries, and The Department of Conservation’ by New Zealand Aerial Mapping Ltd, Hastings, New Zealand.

Data comprises:
•2,516 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.

Index Tiles ONLY, for actual orthophotos see layer Canterbury - Waitaki 0.3m Rural Aerial Photos (2021)

Orthophotography within the Canterbury and Otago Regions captured in 2021. Coverage encompasses parts of Waitaki and Waimate Districts, including the lower reaches of the Waitaki river, the
Hakataramea Valley, and coastal North Otago.

Imagery was captured for Environment Canterbury by Landpro Ltd, 13 Pinot Noir Drive, Cromwell 9310, New Zealand.

Data comprises:
• 933 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:5000 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 tile index layer for specific details, naming conventions, etc.

Imagery supplied as 30cm pixel resolution (0.3m GSD), 3-band (RGB) GeoTIFF. The final spatial accuracy is ±2m at 90% confidence level in clear flat areas for tiles in the area of interest of the survey.

This dataset includes some image tiles labelled as peripheral by the supplier, being imagery captured which was outside the area of interest of the survey. These peripheral tiles may contain artefacts from orthrectifcation, do not have a stated spatial accuracy, and may not be suitable for all purposes. Whether a tile is in the area of interest or is peripheral is noted in the 'AOI' column.
