Critchlow Formed Road Network is A nationwide network of formed roads and walkways accessible to the public.

A formed road is land that has been set aside, and prepared, for vehicle traffic. The surface of the road may be sealed, or it may be rough (wheel tracks), but it must be accessible in all weather conditions by a standard, non-SUV, family type vehicle.

A walkway is land that has been set aside, and prepared, for foot traffic.

All formed roads that are named (publicly or privately owned, formally or informally named) will be represented within the Critchlow road network.

The Critchlow Road Network follows the following basic principles:
1) It is a connected network. All segments in the dataset will perfectly connect with their neighbouring segments where, in the real world, a vehicle can drive between the road sections represented by the connecting segments.
2) It uses nationally consistent naming standards for all roads, a nationally consistent set of prefixes and suffixes, and nationally consistently applied abbreviations for such prefixes and suffixes.
3) It is composed entirely of lines or polylines. No other type of object is acceptable, including multipolylines.
4) It represent real world road features, such as roundabouts, dual carriageways, ramps and slip roads.

A subset of Critchlow 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 Critchlow 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

This layer is 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

A subset of Critchlow NationalMap consisting of contextual lake polygons. Identifies the extent of lakes, lagoons, reservoirs, estuary areas and open bodies of water.

These are named major lakes derived by Critchlow from various paper map sources including street maps in city areas.

A subset of Critchlow NationalMap consisting of the point location of primary and secondary schools. Does not include universities, or preschools.

A subset of Critchlow 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 Critchlow NationalMap consisting of Territorial Authority Administrative Boundaries. These are the second largest administration units after Regional Council areas.

Multiple TAs can occur within one Regional council area, and each TA will include multiple area units, meshblocks and postcodes. For Unitary Authorities the seaward boundary is the outer limits of the territorial sea of New Zealand (12 mile limit).

A territorial authority is defined under the Local Government Act 2002 as a city council or district council.

Territorial authorities are defined at meshblock and area unit level. The Territorial Authority boundaries and classification are released annually on the 1st of January, and on occasion mid year, but there are not always changes from the previous classification.

A subset of Critchlow NationalMap consisting of Regional Council Administrative Boundaries. These are the largest administration units as legally defined by government. They are released annually on the 1st of January to coincide with the update of meshblocks, but there are not always changes from the previous classification.

Regional Councils were established in November 1989 after the abolition of the 22 local government regions. The Local Government Act 2002 requires the boundaries of regions to conform as far as possible to one or more water catchments. When determining regional boundaries, the Local Government Commission gave consideration to regional communities of interest when selecting water catchments to be included in a region. It also considered factors such as natural resource management, land use planning and environmental matters.

Regional councils are defined at meshblock and area unit level. The seaward boundaries of the Regional Councils are the outer limits of the territorial sea of New Zealand (12 mile limit).

Regional councils cover every territorial authority in New Zealand with the exception of Chatham Islands Territory. Generally regional councils contain complete territorial authorities. Where territorial authorities straddle regional council boundaries, the affected area has been statistically defined in complete area units.
