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.
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.

This dataset provides building outlines within mainland New Zealand extracted from multiple years of aerial imagery, allowing you to see change over time, or restrict the dataset to building outlines that match a specific aerial imagery source.

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.

Building roof outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset contains all building outlines which have been extracted from multiple years of aerial imagery available in each region of the country, including the most recent imagery. This dataset includes the dates for which each building existed in the aerial imagery.

Current coverage includes nearly all regions of New Zealand, except parts of rural Auckland, remote parts of Bay of Plenty, Tasman and the Southern Alps, as well as Fiordland, Stewart Island and the Chatham Islands. This dataset will be updated and expanded 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 Lifecycle – stores the relationship between building outlines when one building is split into two or more building outlines, or when multiple building outlines are merged into a single outline. Use this in conjunction with the NZ Building Outlines (All Sources) dataset.

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

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.

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.

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.

Building outlines observed in aerial imagery larger than or equal to 10 square meters are captured in this dataset, and may include structures such as garages and large sheds.

Data vintage

This dataset shows the most recent set of building outlines extracted from the LINZ aerial imagery available on the LINZ Data Service.

Current coverage includes nearly all regions of New Zealand, except parts of rural Auckland, remote parts of Bay of Plenty, Tasman and the Southern Alps, as well as Fiordland, Stewart Island and the Chatham Islands. This dataset will be updated and expanded as new aerial imagery becomes available.

Since aerial imagery is flown only every few years in each region of the country, building outlines only reflect those buildings observed at the date of this aerial imagery capture, and may not reflect buildings constructed after this time period.

Please refer to the NZ Building Outlines Data Dictionary for detailed metadata and information about this dataset.
