This provides a polygon coastline and islands layer which is based on the Topo50 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 and Chatham Islands areas (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.
  3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k) that have had the islands within the main island polygon removed, NZ Auckland Is Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons (Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool.
  4. Lake Onoke from the NZ Lake Polygons (Topo 1:50k) layer and Te Whanga Lagoon from the NZ Chatham Is lagoon polygons (Topo, 1:50k) layer were then erased from the resultant polygon layer to include these two water bodies in the coastline definition.

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

When New Zealand Aerial Mapping (NZAM) went into liquidation in September 2014, LINZ took ownership of their historical photo archive and added it to the Crown Aerial Film Archive, making its photos available to the public.

This layer has been provided to enable potential users to identify the coverage of aerial photography for Mainland NZ flown by NZAM for private contract work between 1939 and 2008. These surveys compliment the Crown photos identified in Historic Aerial Photos, Survey Footprints, CROWN (1936-2005).

If you are aware of any inaccuracies, please contact LINZ at topography@linz.govt.nz. The layer shows the approximate bounding box of each aerial survey undertaken.

The physical Crown Aerial Film Archive is managed for LINZ by WSP New Zealand. Most Crown photographs have been scanned and are available digitally from LINZ upon request. See the Crown Aerial Film Archive historical imagery scanning project for direction on how to access the digitised photos. The photos are not downloadable from the LINZ Data Service.

There are a small number of images held in the Archive that have not been referenced in the LDS layers due to incomplete metadata. WSP NZ will be able to let you know if additional photographs are available in your area of interest.
