NZ Scanned Sounding Sheet Index - Third Party

This index enables you to identify the third party georeferenced TIFF images of sounding sheets held by LINZ for the New Zealand coastal area. Some of these sounding sheets date back to the 1960s. The polygons comprising the index show the extent of each original hard copy sheet - not just the soundings shown on the sheet. The attributes attached to each polygon will enable you to view, amongst other attributes, the data and scale of the bathymetric data shown on the sounding sheet.

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

The georeferenced TIFF images are not downloadable from the LINZ Data Service.

Requests for sounding sheets 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 attribute attached to each polygon representing the sounding sheets 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 images of publically funded New Zealand sounding sheets, which can be readily released under a Creative Commons licence for reuse. View our "NZ Scanned Sounding Sheet Index" dataset to request these sounding sheets.
