"Land cover describes the extent of vegetation, water bodies, built environments, and bare natural surfaces (eg gravel and rock) across New Zealand. Measuring the composition and changes in land cover can help us understand the pressures that different land uses are placing on the biodiversity and functioning of ecosystems.
This data set relates to the ""Land cover"" measure on the Environmental Indicators, Te taiao Aotearoa website."

The LCDB uses satellite images to define polygons for areas with similar land cover types. The land use classifications for the polygons are then stored in a spatial database that can be used for mapping. We used Version 4.0, which covers mainland New Zealand and the nearshore islands but not the Chatham Islands. The LCDB has four major versions (1–4), correlating to the four summer survey periods – 1996/97, 2001/02, 2008/09, and 2012/13. The land cover classification was developed over the first three versions. Classification changes can be tracked to allow comparison between versions. The LCDB contains 33 classes of land cover. These classes were grouped into 13 medium-order classes according a classification provided by Landcare Research. Using this medium-order level classification provides a higher level of confidence in the allocation accuracy (eg for scrub).
