NZ Coastlines and Islands Polygons (Topo 1:500k)

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

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.
