The New Zealand Land Cover Database (LCDB) is a multi-temporal, thematic classification of New Zealand's land cover. It identifies 33 mainland land cover classes (35 classes once the offshore Chatham Islands are included). The classification was revised between versions 1, 2, and 3 but has been consistent thereafter, and always with backward compatibility maintained. Land cover features are described by a polygon boundary, a land cover code, and a land cover name at each nominal time step; summer 1996/97, summer 2001/02, summer 2008/09, summer 2012/13, and summer 2018/19. The data set is designed to complement in theme, scale and accuracy, New Zealand’s 1:50,000 topographic database (www.linz.govt.nz/land/maps/topographic-maps/topo50...). LCDB is suitable for use in national and regional environment monitoring, forest and shrubland inventory, biodiversity assessment, trend analysis and infrastructure planning. The classification used in LCDBv5.0 is presented in the document 'LCDBClassesAtVersion5.pdf' and a table correlating LCDB classes over all versions is presented in the document 'LCDBClassCorrelations.pdf'. Both of these are among the accessory documents to this dataset in the LRIS portal (lris.scinfo.org.nz/). LCDB version 5.0 was released in January 2020 and includes corrections to all time steps 1997/97, 2001/02, 2008/09, 2012/13 and 2018/19 for both the New Zealand mainland and Chatham Islands. A description of work undertaken for this release (including that of all earlier releases) is presented in the Lineage section. Of particular note at version 5.0 is the addition to LCDB, of attributes designed to readily identify and monitor wetlands over time and a similar capability to manage significant coastal changes. “EditAuthority” and "EditDate" are attributes, maintained since version 3.0 to indicate authorship and nominal date of polygon mapping, edit or change. Errors in the data due to misclassification (rather than land cover change) or poor delineation can be reported to Landcare Research for inclusion in the next release using the online feedback facility in lris.scinfo.org.nz/.

Threatened Environment Classification look up table. Join this table with the TEC/LENZ grid using grid value and the LENZlvl4_no numeric code in the look up table to achieve correct relational join.

This table shows for each of the 500 LENZ level IV environments (identified by name and number) the percent of land area with indigenous cover remaining in 2002, 2008 and 2012 (labelled Nat02Pct, Nat08Pct, Nat12Pct; using satellite imagery of the corresponding timestamps as classified in LCDB4), and the percent of land area protected for natural heritage protection in 2004 and 2012 (labelled Prot02Pct.1c, Prot12Pct). It also provides the Threatened Environment Classification categories for 2002 (TEC02.Class, classified using the Nat02Pct and Prot02Pct.1c values provided), and the Threatened Environment Classification 2012 categories (TEC12.Class, classified using the Nat12Pct and Prot12Pct values provided).

This data set (LCDB v5.0Version Trace) allows users to track changes back to the previous version (v4.1), and to reconcile derived quantities, such as the total area of a class in a region, to those derived from the earlier LCDB version. Additionally the authority (and date) for mapping the change is recorded in this database where such a change has been manually mapped.However sometimes when a feature has been removed, and the change area becomes part of a larger "background", the EditDate will pertain to the background area. DO NOT use this dataset to assess real vegetation change over time. Rather use the latest available LCDB version which will contain vegetation cover for all timesteps. This Version Trace dataset is only provided to help reconcile with an analysis done on an earlier version of the LCDB. Similar datasets were provided to trace LCDB2 ==> LCDB v3.0, LCDB v3.0 ==> LCDB v3.3, LCDB v3.3 ==> LCDB v4.0, and LCDB v4.0==> LCDB v4.1. Note however, we earlier called the dataset "Change" rather than "Version Trace", e.g. "LCDB v4.0 Change".
