Kawakawa-Orere Data

A buoy is a floating object moored to the bottom in a particular place, as an aid to navigation or for other specific purposes. A cardinal buoy is used in conjunction with the compass to indicate where the mariner may find the best navigable water. It is placed in one of the four quadrants (North, East, South and West), bounded by inter-cardinal bearings from the point marked.

This layer is a component of the Topo500 data. The Topo500 map series will, when it is created, provide updated topographic mapping for the New Zealand mainland at 1:500,000 scale.

This dataset covers 74% of the WRAPS area with the remaining capture scheduled this season. The orthos have been supplied as ‘draft’ as you can expect to see some distorted bridges. These will be corrected in the final ortho production. A final colour balance over the entire project area will also be undertaken and a full replacement data set supplied.

Orthophotography within the Waikato Region captured in the summer flying seasons between 2020 and 2023. Coverage encompasses The area of capture is located within the upper North Island and encompasses all or part of 11 territorial authorities. It also includes parts of Bay of Plenty, Hawke's Bay and Manawatū-Whanganui.

Imagery was captured for Waikato Regional Aerial Photography Service (WRAPS) 2021 by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.

Data comprises:
• 2807 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) uncompressed GeoTIFF. The final spatial accuracy is ±0.5 at 95% confidence level in clear flat areas.
