SW Pacific Scanned Sounding Sheet Index

  • Added 16 Oct 2016
  • Updated 15 Mar 2021

This index enables you to identify the georeferenced TIFF images of sounding sheets held by LINZ throughout the SW Pacific region. Some of these sounding sheets date back to the 1950s. 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 date 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 this dataset.
The georeferenced TIFF images are not downloadable from the LINZ Data Service
Requests for sounding sheets should be sent to 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 sounding sheets of interest.
The provision of this 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.
