World Map Background represents grid cells of 30 by 30 degrees that cover the world.

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)](http://data.linz.govt.nz/layer/258-nz-coastlines-topo-150k/) - [NZ Island Polygons (Topo 1:50k)](http://data.linz.govt.nz/layer/288-nz-island-polygons-topo-150k/) - [NZ Auckland Is Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/959-nz-auckland-is-island-polygons-topo-150k/) - [NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/932-nz-campbell-is-motu-ihupuku-island-polygons-topo-150k/) - [NZ Antipodes Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/978-nz-antipodes-is-island-polygons-topo-125k/) - [NZ Kermadec Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/908-nz-kermadec-is-island-polygons-topo-125k/) - [NZ Bounty Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/992-nz-bounty-is-island-polygons-topo-125k/) - [NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/893-nz-snares-is-tini-heke-island-polygons-topo-125k/) - [NZ Chatham Is island polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/86-nz-chatham-is-island-polygons-topo-150k/) 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.

[The Place Names Gazetteer](http://www.linz.govt.nz/placenames/find-names/nz-gazetteer-official-names/nzgb-gazetteer) contains **official** and **unofficial** place names under the jurisdiction of the New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB). Official place names are those that have been assigned, altered, adopted, approved, and validated under the NZGB Act 2008 or through other statutes that assign official names, for example, Treaty settlement legislation. Unofficial place names are those that have not been processed under the NZGB Act 2008 or through other relevant statutes. Data is extracted from Land Information New Zealand’s (LINZ) ‘New Zealand Gazetteer of Official Geographic Names’, which is maintained by the NZGB Secretariat. Geographical coverage encompasses New Zealand, the Ross Dependency of Antarctica, and the Continental Shelf of New Zealand. The NZGB has naming jurisdiction over: - natural features such as mountains, peaks, valleys, glens, forests, lagoons, swamps, creeks, streams, rivers, fords, lakes, glaciers or ice features, bays, islands or harbours (including man-made features of the same type) - railways or railway stations, but not railway features such as marshalling yards, transfer sites, or track point locations - places, i.e. cities, towns, villages, sites, areas, or similar places, including suburbs and localities - undersea features - Crown protected areas - Districts and regions (altering only if requested by the local authority) Each name is provided with a location represented by a point. More complex geometry (e.g lines for rivers or areas for suburbs) is not currently available. Each geographic feature has one or more place names associated with it. Place names usually comprise two components – ‘specific’, being for the proper noun, and ‘generic’, being a description of the geographic feature type. Information provided for each place name may include: name; name status (whether official or unofficial); geographic feature type; authority by which an official name became official; district within which the name is located; geographic location; reference information; history/origin/meaning; and additional notes. Not all information is available for all names. Positional accuracy is generally the same as 1:50K mapping. Information accuracy reflects information at the time of original capture.

The Land Use Map is composed of New Zealand-wide land use classifications (12) nominally at 1 January 1990, 1 January 2008, 31 December 2012 and 31 December 2016 (known as "1990", "2008", "2012" and "2016"). These date boundaries were dictated by the First and Second Commitment Periods of the Kyoto Protocol. The layer can therefore be used to create either a 1990, 2008, 2012 or 2016 land use map depending on what field is symbolised.

The StockEx LSL 2021 proposed layer identifies proposed areas of "low slope land" where the Resource Management (Stock Exclusion) Regulations 2020 would apply if the low slope land map was updated as proposed in the "Stock exclusion regulations: Proposed changes to the low slope map" (MfE, 2021) discussion document. The layer shows the area of land defined as low slope land. These areas have a local mean slope is less than or equal to 5 degrees and are below 500m in altitude. Areas of lakes and ponds, estuarine open water, built-up areas, transport infrastructure, depleted grass, tall tussock grassland and urban parkland, as defined in Land Cover Database 5, are also excluded.

The Chatham Islands Land Use Map is composed of 12 land use classifications nominally at 1 January 1990, 1 January 2008, 31 December 2012 and 31 December 2016 (known as "1990", "2008", "2012" and "2016") and was created using broadly the same methodology as was used for mainland LUCAS NZ LUM 2016. These date boundaries were dictated by the First and Second Commitment Periods of the Kyoto Protocol. The layer can therefore be used to create either a 1990, 2008, 2012 or 2016 land use map depending on what field is symbolised.

This LIDAR DEM extent for NZ feature class has last been updated in May 2022 and will need to be reviewed frequently. Future updates in this DB are planned to happen occasionally.
