Abstract
|
The curvature of the bathymetry dataset from the Queen Charlotte Sound / Tōtaranui and Tory Channel / Kura Te Au Hydrographic
Survey LINZ Project HYD-2016/17-01 (HS51).
Curvature is the second derivative of the surface, or the slope-of-the-slope. A positive curvature indicates the surface
is upwardly convex at that cell. A negative curvature indicates the surface is upwardly concave at that cell. A value of
0 indicates the surface is flat.
These data are in raster geotiff format and include ESRI layer files and QGIS GML files for symbology.

Purpose
|
The National Institute of Water and Atmospheric Research Ltd (NIWA) was contracted in October 2016 by Land Information New
Zealand (LINZ) to undertake hydrographic surveying services for the Queen Charlotte Sound / Tōtaranui and Tory Channel /
Kura Te Au Hydrographic Survey (HS51). This work was commissioned by a partnership between LINZ and the Marlborough District
Council (MDC).
The commissioned survey comprises both hydrographic (LINZ) and habitat mapping (MDC), requirements which are met by a NIWA-led
partnership with Discovery Marine Limited (DML) under LINZ project HYD-2016/17-01 (HS51) Contract No 20058.
