This layer is a component of the Topo500 data. The Topo500 map series will, when it is created, provide updated topographic mapping for the New Zealand mainland at 1:500,000 scale.

A tract of land covered by trees native to New Zealand.

This provides a polygon coastline and islands layer which is based on the Topo500 products. It is a combination of the following layers:

• NZ Coastlines (Topo, 1:500k)
• NZ Island Polygons (Topo, 1:500k)

This topographic coastline is the line forming the boundary between the land and sea, defined by mean high water.

Islands from the NZ Island Polygons layer that lie within the NZ Coastline area (i.e. islands in lakes, rivers and estuaries) have been removed.

The GIS workflow to create the layer is:

1. NZ Coastlines were converted from a polyline to a polygon using a polyline to polygon tool.
2. The resulting coastal polygon was then used as an input into an erase tool and run against the NZ Island Polygon layer to remove all islands lying within the NZ Mainland and Stewart Island.

For more detailed description of each layer refer to the layer urls above.

The Ant50 map series provides topographic mapping within the Ross Dependency, Antarctica

Digital images of the maps are also publicly available from www.linz.govt.nz/topography/topo-maps/antarctic-to...

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.

Geographic name holds the proper noun of certain objects within the Topo databases. Geographic_name does not apply to roads, railway lines, or descriptive text - eg 'Brunner Mine' would be a Geographic_name but 'mine disused' is held in the descriptive_text feature
