This dataset was last updated on NationalMap Data Service on 02 Feb 2018.

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 polygons of New Zealand islands (named), excluding those on lakes. This dataset represents the outline of the New Zealand landmass at a small scale. Derived by Critchlow from LINZ 1:50k Topo maps.

This dataset was last updated on NationalMap Data Service on 15 Jun 2017.

A subset of Critchlow NationalMap consisting of Riverbeds represented by polygons to display true river width, derived by Critchlow from paper Topographic maps. Greater detail in City areas where applicable. Due to large braided stream networks, a river can often be seen as significantly less than its bed, in the dry season some tracks are located on river beds, these indicate the extent of the river at full capacity.

This dataset was last updated on NationalMap Data Service on 02 Feb 2018.

A subset of Critchlow NationalMap consisting of contextual national parks, forest parks, urban recreational parks, golf courses, show grounds, zoos, racetracks and conservation reserves among others. The park boundaries are derived by Critchlow from various sources (LINZ paper maps in City areas) and aligned to land parcel boundaries, and are updated and maintained by Critchlow. This layer also includes the Canterbury earthquake redzoned areas as supplied by CERA ceraarchive.dpmc.govt.nz/documents/public-geospati....

This dataset was last updated on NationalMap Data Service on 10 Oct 2017.

A subset of Critchlow NationalMap consisting of Built Up areas defined by LINZ and modified by Critchlow to encompass the extent of built up urban areas including commercial and residential categories. These are named urbanised areas.

This is a sample of the NationalMap - BuildUpArea Table. For options of obtaining this for the whole country please visit: www.nationalmap.co.nz/delivery-and-pricing

'Urban' is defined as 'of, pertaining to, or constituting a city or town; occurring in or characteristic of a city or town'. In the majority of cases, an urban area will be characterised by high population density, small land holdings (regularly less than 0.4 hectares), and zoning that is compatible with high density commercial, industrial and/or residential activity.

Critchlow modifications to the original dataset include the identification of detailed boundaries for built up areas from the latest available aerial imagery supplied by LINZ. Therefore the dataset contains whole urban areas not included in the original LINZ dataset.

This dataset was first added to NationalMap Data Service on 10 Apr 2017.

A subset of Critchlow NationalMap consisting of contextual river features (major rivers and tributaries) represented by line, polyline and polygon objects derived by Critchlow from paper Topo maps (mainly LINZ).

These features indicate the location of rivers. Where significant flow or width and depth of a river is evident these are represented by polygons. Polygon segments are also evident in urban areas to provide a more complete representation. Line networks show rural or highland areas where flow is not significant. Rivers are named where available.
