This provides a polygon coastline and islands layer which is based on the Topo250 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:
For more detailed description of each layer refer to the layer urls above.

In addition to contour lines, relief shading helps visualise the terrain. Hills and valleys are shaded as if they were illuminated from the north-west.
Relief layers were generated for each sheet, and specifically for use in the Topo250 map series. There may be subtle differences in the relief shading of adjacent map sheets.
The Topo250 map series provides topographic mapping for the New Zealand mainland and Chatham Islands, at 1:250,000 scale.
