Title
NZ Chatham Is Topo50 Data
Date
Abstract
This dataset contains all individual vector layers of the NZ Chatham Is Topo50 available through the LINZ Data Service.
This grouping of NZ Chatham Is Topo50 layers will allow you to quickly view and download this collection of related layers.
See the Topographic Data Dictionary (http://www.linz.govt.nz/data/linz-data/topographic-data/topographic-specifications) for detailed information about each layer, and our background information on Topo50 (http://www.linz.govt.nz/land/maps/linz-topographic-maps/topo50-maps/topo50) to understand this data.
For the latest changes to this data, see the Topo50 Update History (http://www.linz.govt.nz/land/maps/linz-topographic-maps/topo50-maps/topo50-update-history)
These layers are 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.
Purpose
Topo50 is the official topographic map series used by New Zealand emergency services.
When using Topo50 data, please be aware of the following: 1. The existence of a road or track does not necessarily indicate public right of access.
2. Closed tracks are defined as being no longer maintained or passable and should not be used by recreationalists.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.
3. Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data.
4. Contours and spot elevations in forest and snow areas may be less accurate.
5. 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.
6. 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.

LINZ and our predecessors have been responsible for national topographic mapping in New Zealand for more than a hundred years.
The first digital data at 1:50,000 was created in the late 80's and early 90's by scanning the 1:50,000 maps that existed at the time (known as the NZMS 260 series, which replaced the imperial NZMS 1 series at 1inch to 1 mile)
The raw data was created by photogrammetrists who from 1974 to 1997 mapped the country 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.
From 1994 to 2006 LINZ used orthophotos to update the map data. Today the map data is updated primarily from satellite imagery, and data supplied from Department of Conservation, Transit NZ and others.
LINZ releases regular updates of the Topo50 maps and data; for details refer http://www.linz.govt.nz/topography/topo-maps/topo50/update-history
Some features are subject to change more than others. For example in any given map revision, it is likely that road data will undergo more change than, for example, fumeroles. However, all data is examined during a full data revision.
