Data

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.

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.

This 8m Digital Elevation Model (DEM) was originally created by Geographx (geographx.co.nz) and was primarily derived from January 2012 LINZ Topo50 20m contours (data.linz.govt.nz/layer/768).

Spatial accuracy is nominally the same as for the LINZ source data: 90% of well-defined points are within ±22 metres horizontally and within ±10 metres vertically.
For a full description of the how the DEM was generated refer to this layer’s metadata.

In addition to contour lines, relief shading helps visualise the terrain. Hills and valleys are shaded as if they were illuminated from the north-west.

Relief layers were generated for each sheet, and specifically for use in the Topo50 map series. There may be subtle differences in the relief shading of adjacent map sheets.

The Topo50 map series provides topographic mapping for the New Zealand mainland and Chatham Islands, at 1:50,000 scale.

The Topo250 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands at 1:250,000 scale.

Along with the paper-based Topo250 map series, digital images of the maps are also publicly available.

Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.

Please be aware of the following:

• The existence of a road or track does not necessarily indicate public right of access.
  

• Closed tracks are defined as being no longer maintained or passable and should not be used by recreationalists. The Department of Conservation or other authorities should be contacted for the latest information on tracks and huts.
  

• Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data.
  

• Contours and spot elevations in forest and snow areas may be less accurate.
  

• Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies
  

• Permits may be required to visit some sensitive and special islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.

This layer shows the New Zealand mainland sheet extents for the historic NZMS 260 map series.

The NZMS 260 Topographic map series began in 1977 and ended production in 2009. The series was produced at the 1:50,000 scale.

NOTE: The NZMS260 map series has now been superseded by NZTopo50. To download the NZTopo50 Map sheets please refer to NZ Topo50 Mapsheets. For further information and latest editions of Topographic maps for the whole of New Zealand see here
