Digital Elevation Model (DEM) created from RTK GPS points and echo soundings collected in April 2012 for the Rakaia Lagoon and the beach barrier at the southern end. These field data were combined with 2010 LiDAR data for the inaccessible landward side of the lagoon to generate a lagoon DEM.

-
A closed depression formation forming a closed loop and representing an area of lower ground of less than the vertical interval. Data Dictionary for depform_edge: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-depform_edge This layer is a component of the Ant50 map series. This is the topographic mapping carried out at 1:50,000 scale by LINZ within the Ross Dependency, Antarctica.
-
An imaginary line that connects points of equal height value eg the elevation of the land surface above or below a vertical datum, in this case of LINZ topographic mapping, this is Mean Sea Level. Data Dictionary for contour: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-contour Although captured and presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series.

Data Dictionary for contour: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-contour This layer is a component of the Topo50 map series. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham and New Zealand's offshore Islands, at 1:50,000 scale.

River cross-sections of the active part of the river channel were surveyed at 500m intervals over a distance of 25km between Opuha Dam and the Opihi confluence. Data were collected with Trimble R8 RTK GPS by wading the river adn are stored in an Excel spreadsheet.
-
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 Data Dictionary for height_pnt: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-height_pnt Although captured and presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series.

Data Dictionary for contour: http://apps.linz.govt.nz/topo-data-dictionary/index.aspx?page=class-contour This layer is a component of the Topo50 map series. The Topo50 map series provides topographic mapping for New Zealand and it's offshore dependancies, at 1:50,000. Further information on Topo50: http://www.linz.govt.nz/topography/topo-maps/topo50
