Published Chart: Charting Around New Zealand (CANZ) Group (2008), 'New Zealand Region Bathymetry',
1:4,000,000 scale at 46°S on Mercator projection, NIWA Chart, Miscellaneous Series No. 85, National Institute of Water and Atmospheric Research, Wellington, New Zealand

Geographic Coverage: In the edgematching of this sheet with GEBCO sheet G.08, the bathymetry was taken from sheet G.08 for the following areas:
24°-31°S,157°-158.5°E; 47°-54°S,157°-165°E; 54°-57.5°S,157°-163.5°E

The bathymetry was compiled by NIWA at a scale of 1:1 million using a series of 18 separate Ocean Plotting Sheets on which the soundings were plotted. Each author (as listed above) worked on the interpretation and contouring of 3-4 sheets each and gravity data were used to assist in the interpretation. The resulting contours (at intervals of 250m) were then digitized and used in the production of the 1:4 million scale chart.

The bathymetry was compiled from data held at:
National Institute of Water and Atmosphere (NIWA)
Hydrographic Office of the Royal New Zealand Navy
US National Geophysical Data Centre
South Pacific Applied Geoscience Commission (Fiji);
from published scientific papers; and from recent swath bathymetric surveys funded by Institut Francais de Recherche pour'Exploitation de la Mer (IFREMER), France, NIWA, LINZ and Seabed Mapping New Zealand Ltd.

The shallow water contours (50m, 100m, 150m and 200m) were compiled from a
database made up of the digitized contours from the NIWA coastal (1:200,000)
chart series.

Bathymetric data for Texas bays and offshore waters. Locations generated from latitude/ longitude coordinates provided by NOAA. Data may not be current and are not to be used for navigation.

Locations of bathymetric values generated by GLO personnel from coordinate data provided by the National Oceanic and Atmospheric Administration (NOAA).

Point locations were generated from coordinate data given in ASCII format. Some points have been eliminated to facilitate cartographic display and may not adequately depict underwater features. Occasional points may have erroneous depth values. The bathymetry of some bay and nearshore areas has changed significantly since the source data were collected.

General map 1:1,000,000 is a dataset depicting the terrain and covering the whole of Finland. The most important target groups are water systems, traffic route networks and administrative borders. The administrative borders, the nomenclature and the traffic route network are updated every year and the other elements every 5 years.
