This dataset consists of building outlines for the majority of New Zealand but does not contain full coverage. It is part of a pilot to understand the benefit of making building outlines data openly available through the LINZ Data Service.
Building outlines are 2D shapes of the edge of a building as visible from aerial imagery, most commonly the roofline edge. It includes spaces such as decks, garages and porches. Each polygon represents a building outline. The outlines were extracted from orthoimagery using an automated process.
Resolution of the imagery used for capture ranges from 50cm pixel resolution (0.5m GSD) to 10cm pixel resolution (0.1m GSD). Please refer to the ‘imagery_source’ attribute for details.
This is a pilot dataset and is not complete for the whole of New Zealand
While some checks on the data have taken place, there are still errors present
