West Coast Region Data - Page 12

Index Tiles ONLY, for actual orthophotos see layer West Coast 0.4m Rural Aerial Photos (2009 - 2011)

Orthophotography for the West Coasti region taken during 2009 to 2011. Coverage encompassed ~60% of the West Coast Regional councils area.

Imagery was captured by NZ Aerial Mapping Ltd, 208 Warren Street, PO Box 6, Hastings 4156, New Zealand

Data has subsequently been provided to LINZ and this comprises:
• 1,623 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 +/-2.5m (@ 90% confidence).

This layer contains the DEM for LiDAR data in the West Coast Region, captured between 2020 and 2022.

• The DSM is available as layer West Coast LiDAR 1m DSM (2020-2022).

• The index tiles are available as layer West Coast LiDAR Index Tiles (2020-2022).

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

LiDAR was captured for West Coast Regional Council by Aerial Surveys between 16 May 2020 and 14 February 2022. These datasets were generated by Aerial Surveys and their subcontractors. Data management and distribution is by Land Information New Zealand.
