Data

This table provides the relationships between building outlines within mainland New Zealand when buildings are split or merged.

A building outline is a 2D representation of the roof outline of a building which has been classified from LINZ aerial imagery using a combination of automated and manual processes to extract and refine a building roof outline.

Data vintage

This dataset does not include building outline geometry, but provides the linkages between building_id's from different aerial imagery sources in the NZ Building Outlines (All Sources) dataset when building outlines change from single outlines split into multiple outlines, and from multiple outlines merged as single outlines.

This dataset will be updated with changes in building_id relationships as new aerial imagery becomes available.
Please refer to the NZ Building Outlines Data Dictionary for detailed metadata and information about this dataset.

Related building outlines data

NZ Building Outlines (All Sources) - directly related to this dataset, it contains all combinations of building outlines from multiple years of imagery that have existed since the beginning of this dataset.

NZ Building Outlines - provides current building outlines only derived from the latest LINZ aerial imagery.

The Topo50 map series provides topographic mapping for the New Zealand mainland, the Chatham Islands, and offshore islands at 1:50,000 scale.

Along with the paper-based Topo50 map series, digital images of the maps are also publicly available.

Georeferenced raster digital images are provided at a resolution of 300 DPI. Georeferencing allows adjacent maps to be accurately and automatically aligned within GIS systems.

Please be aware of the following:

• Representation of a road or track does not necessarily indicate public right of access. For access rights, maps and other information, contact the New Zealand Walking Access Commission - www.walkingaccess.govt.nz

• The Department of Conservation and other agencies should be contacted for the latest information on tracks and back country huts. Closed tracks are defined as being no longer maintained or passable and should not be used.

• Not all aerial wires, cableways and obstructions that could be hazardous to aircraft are held in the data.

• Contours and spot elevations in forest and snow areas may be less accurate.

• Not all pipelines including both underground and above ground are held in the data or shown on the printed maps. For the latest information please contact the utility and infrastructure agencies

• Permits may be required to visit some sensitive and special islands and areas. Contact the Department of Conservation to see if you need to apply for a permit.

A structure on top of a hill, usually coloured black and white, used as a physical reference point by surveyors to determine location. The symbol shown on the map includes the elevation and trig identification code for beaconed trig stations.

Data Dictionary for trig_pnt: The NZ Topographic Data Dictionary is yet to be updated for trig points.

These topographic trig points are derived from New Zealand geodetic marks data which can also be accessed through the LINZ Data Service: NZ Geodetic Marks and NZ Geodetic Vertical Marks.
