Topographic Data

A subset of NationalMap consisting of a combination of vegetation layers extracted from the LINZ web portal.

The combined vegetation layers consists of:

• Exotic: Land covered by trees not native to New Zealand.
• Mangrove: Coastal or brackish or saline area covered by specially adapted trees.
• Native forest: Land covered by trees native to New Zealand.
• Orchard: Land covered by pip or stone fruit or vegetation.
• Scrub: Land covered by vegetation less than 3 m high.-Vineyards: Land covered by vines e.g. grapes, kiwifruit etc.

These layers are a component of the Topo50 map series. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham and New Zealand's offshore islands, at 1:50,000 scale. Further information on Topo50: www.linz.govt.nz/topography/topo-maps/topo50

A subset of NationalMap consisting of a combination of Water layers extracted from the LINZ web portal.

The combined Water layer consists of the following water body polygons :

• River: natural, flowing body of water emptying into an ocean, lake or other body of water and usually fed along its course by converging tributaries.
• Lake: any standing body of fresh inland water.
• Pond: area of shallow water with walls or banks created for a specific purpose.
• Reservoir: receptacle in which a large quantity of water is stored - Canal: artificial open waterway used for transportation, waterpower or irrigation.
• Lagoon: sheet of salt water separated from the open sea by sand, shingle banks or a road embankment.

These layers are a component of the. Topo50 map series. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham and New Zealand's offshore islands, at 1:50,000 scale. Further information on Topo50: www.linz.govt.nz/topography/topo-maps/topo50

A subset of NationalMap consisting of a combination of landcover data extracted from the LINZ web portal.

The landcover data consists of the following types of cover:

• Swamp: A wet or moist region with water standing on or just below the surface of the ground, and usually covered by a growth of vegetation
• Ice: A region of permanent ice
• Mud: An area of wet, soft earthy matter
• Rock: Coastal rocks; rocks between high and low tide
• Sand: Sand, crushed rock, shells etc. smaller than 2mm in size
• Scree: Mountain slope covered with small stones
• Shingle: Crushed rock, shells etc. larger than 2mm in size
• Gravel pit: Area used for the extraction of coarse sand and small water-worn or pounded stones, used for paths and roads
• Landfill: A portion of land on which refuse, solid or semi-solid waste, is dumped and then covered with earth
• Moraine: An accumulation of boulders, stones or other debris carried and deposited by a glacier
• Pumice: Area used for the extraction of pumice

A subset of NationalMap consisting of a combination of historic sites, monuments, and fortification extracted from the LINZ web portal.

The Topographic historic layer consists of the places where there has been historic activity, where there is a historic object, or the structures erected as a memorial can be found in this layer. Also contained are a combination of European fortifications and Maori defensive earthworks extracted from the LINZ web portal. The fortification data consists of: - Redoubt points: European fortification of the New Zealand Wars- Pa points: Defensive earthworks constructed by Maori at any time between the fifteenth and nineteenth centuries which were still visible as a topographical object at the time the first edition of the map was published.

The recreation data consists of:

• Showgrounds: Data of public areas containing buildings, paddocks etc. for the display of livestock, agricultural produce, machinery, and the like
• Sports fields: Data of fields on which sporting activities are carried.- Racetracks: data of courses laid out for racing
• Golf courses: Data of areas set aside for playing golf.
