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.

LINZ and our predecessors have been responsible for national topographic mapping in New Zealand for more than a hundred years.

The first digital data for the NZ Offshore Islands at 1:25,000 and 1:50,000 was created in the late 80's and early 90's by scanning the maps that existed at the time (the NZMS 272 series)

The raw data was created by photogrammetrists who from 1974 to 1997 mapped the islands from overlapping pairs of aerial photographs. Cartographers then took the data and added symbols and text, and created the colour separations needed to produce the printed maps.

In 2009 and 2010 LINZ used satellite imagery and data supplied from the Department of Conservation to update the offshore islands data. Printed maps (in hardcopy and digital form) in are also available.
