The NZ 1:1k Tile Index dataset provides a 1:1,000 scale index for aerial imagery and LiDAR datasets.

This 1:1k tile index is part of a collection of indexes which are referenced to the NZ 1:50k Tile Index dataset.

Like the NZ 1:50k Tile Index, these larger scale indexes support mapping of NZ mainland and coastal areas up to 50m in depth.

The dataset includes the following attributes:

index_tile_id: Unique identifier for the NZ 1:1k Tile Index table.
sheet_code_id: The corresponding sheet code of the NZ 1:50k Tile Index.
scale: The map scale of the index tiles.
tile: The combination of the row and column numbers of the index tiles.

The NZ 50k Tile Index dataset provides a 1:50,000 scale base index for larger scale indexes used for aerial imagery and LiDAR datasets.

This index is different from Topo50 Map Sheets in that there are no overlapping index polygons in this dataset.

This index also expands further into the sea to support future mapping in coastal areas and encompasses all offshore locations up to 50m in depth.

The dataset includes a map sheet code consistent with those from Topo50 Map Sheets, and an attribute for each tile to show whether there is a corresponding Topo50 map sheet with matching location coverage.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers:

• NZ Coastlines (Topo 1:50k)
• NZ Island Polygons (Topo 1:50k)
• NZ Auckland Is Island Polygons (Topo, 1:50k)
• NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)
• NZ Antipodes Is Island Polygons (Topo, 1:25k)
• NZ Kermadec Is Island Polygons (Topo, 1:25k)
• NZ Bounty Is Island Polygons (Topo, 1:25k)
• NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)
• NZ Chatham Is island polygons (Topo, 1:50k)

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.

This layer is a component of the Topo50 map series. The Topo50 map series provides topographic mapping for New Zealand and it's offshore dependancies, at 1:50,000.
For some small islands the printed map scale is 1:25,000. Although presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series.
