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

Pulse density is 2 pulses/square metre.

Refer to individual survey reports for accuracy statistics.

Vertical datum is NZVD2016.

A pipeline is a string of interconnected pipes used for the transport of matter, nowadays mainly oil or gas. A submarine or land pipeline is a pipeline lying on or buried under the seabed or the land.

S-57 Object Class: Pipeline, submarine/on land

Index Tiles ONLY, for actual orthophotos see layer Dunedin 0.1m Urban Aerial Photos (2018-2019)

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.

• The DSM is available as layer Otago - Dunedin and Mosgiel LiDAR 1m DSM (2021).

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

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

LiDAR was captured for Otago Regional Council by AAM Ltd on 24 June 2021. These datasets were generated by AAM 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 8 pulses/square metre.

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.
