This index enables you to identify the freely available georeferenced TIFF images of sounding sheets held by LINZ for the New Zealand coastal area. Some of these sounding sheets date back to the 1930s. 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 email@example.com 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.
LINZ also holds images of New Zealand sounding sheets provided by third parties, which are subject to different licencing terms and conditions. View our "NZ Scanned Sounding Sheet Index – Third Party" dataset to request these sounding sheets.
