This provides a polygon coastline and islands layer which is based on the Topo50<\/SPAN><\/P>

products. It is a combination of the following layers:<\/SPAN><\/P>

<\/P>

- [NZ Coastlines (Topo<\/SPAN><\/P>

1:50k)](http://data.linz.govt.nz/layer/258-nz-coastlines-topo-150k/)<\/SPAN><\/P>

- [NZ Auckland Is Island Polygons (Topo,<\/SPAN><\/P>

Islands from the NZ Island Polygons layer that lie within the NZ Coastline and<\/SPAN><\/P>

Chatham Islands areas (i.e. islands in lakes, rivers and estuaries) have been<\/SPAN><\/P>

removed.<\/SPAN><\/P>

<\/P>

The GIS workflow to create the layer is: <\/SPAN><\/P>

<\/P>

1. NZ Coastlines were converted from a polyline to a polygon using a polyline to<\/SPAN><\/P>

polygon tool.<\/SPAN><\/P>

2. The resulting coastal polygon was then used as an input into an erase tool<\/SPAN><\/P>

and run against the NZ Island Polygon layer to remove all islands lying within<\/SPAN><\/P>

the NZ Mainland and Stewart Island. <\/SPAN><\/P>

3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k)<\/SPAN><\/P>

that have had the islands within the main island polygon removed, NZ Auckland Is<\/SPAN><\/P>

Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ<\/SPAN><\/P>

Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons<\/SPAN><\/P>

(Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is /<\/SPAN><\/P>

Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool. <\/SPAN><\/P>

4. Lake Onoke from the NZ Lake Polygons (Topo 1:50k) layer and Te Whanga Lagoon<\/SPAN><\/P>

from the NZ Chatham Is lagoon polygons (Topo, 1:50k) layer were then erased from<\/SPAN><\/P>

the resultant polygon layer to include these two water bodies in the coastline<\/SPAN><\/P>
