Orthophotography in the Wairoa district taken in the flying season (summer period) 2014 - 2015. Coverage is of urban areas with the Wairoa District Council area.

Imagery was captured for the ‘Wairoa District Council’ by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany,0632, New Zealand.

Data comprises:
•514 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. 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 ±0.2m @ 95% confidence level in clear open spaces (2 sigma) over area of interest.

Index tiles for this dataset are available as layer Wairoa 0.1m Urban Aerial Photos Index Tiles (2014-15)

This index enables you to identify the third party bathymetric data held and used by LINZ on its NZ coastal nautical charts. Some of our data holdings date back to the 1950s. The polygons comprising the index show the extent of the survey datasets. The attributes attached to each polygon will enable you to view, amongst other attributes, the age and quality of the bathymetric data.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset.

The bathymetric data is not downloadable from the LINZ Data Service. Datasets prior to the year 2000 are predominantly available only as georeferenced TIFF images of the original hard copy sounding sheets. Data post-2000 is often available as both georeferenced TIFF images and as digital data files (vector data in plain text format).

Requests for the bathymetric data should be sent to hydro@linz.govt.nz with “Hydro Bathy Data” in the subject line. Requests must, as a minimum, specify the id, chart_no and serial_no as shown in the attributes attached to each polygon representing the datasets of interest.

The provision of third party funded bathymetric data may be subject to some delay as LINZ confirms with the data owner that they are happy for their data to be released. The owner may attach conditions to the release of their data.

LINZ also holds publically funded New Zealand bathymetric data, which can be readily released under a Creative Commons licence for reuse. View our "NZ Bathymetric Data Index" dataset to request this data.
