20m contours layer from the LINZ 1:50,000 NZTopo database.

Definition: An imaginary line that connects points of equal height value eg the elevation of the land surface above or below a vertical datum.

1m contours for urban Wellington including Makara Beach and Makara Village. Based on a DTM created from 2006 LiDAR and updated using 2009 photogrammetry masspoints and breaklines where significant changes in the terrain were detected. WCC generalised the contours by up to 0.2m in order to reduce the number of vertices in the dataset. Contours generated from LiDAR and photogrammetry should not be used for detailed engineering design.

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.

Height points layer from the LINZ 1:50,000 NZTopo database, also known as spot heights.

Definition: A height above a vertical datum, represented on a map by a dot locator with the elevation printed beside the dot. Unlike trigonometrical stations, spot heights are not identifiable on the ground.
