This database (LCDB) is a thematic classification of land cover and land use classes. The current version LCDB v3 contains 33 classes designed to be compatible with earlier LCDB versions. The polygon features contain a code and boundary representing the land cover type at each of three periods; summer 1996/97, summer 2001/02, and summer 2008/09. The data set was designed to be compatible in scale and accuracy with Land Information New Zealand’s 1:50,000 topographic database. LCDB is intended to be used in areas such as state of environmental monitoring, forest and shrubland inventory, biodiversity assessment, trend analysis and infrastructure planning.
The list of classes used in LCDB v3.0 can be found in the document LCDB2-3 Correlation Table along with the mapping from the class set used in the previous version (LCDB-2). This document is available as an attachment to this dataset (see below), and on the LCDB project site (www.lcdb.scinfo.org.nz).
LCDB v3.0 was released in July 2012 and includes non-temporal edits to the summer 1996/97, summer 2001/02 time periods along with the new summer 2008/09 period. A change layer, “LCDB v3.0 change” (lris.scinfo.org.nz/layer/308-lcdb-v30-change) is available to indicate both non-temporal and temporal changes made between LCDB-2 and LVCDB v3.0, The non-temporal changes include errors in the earlier mappings, step artefact removal, and coastline adjustments. An “authority” attribute is also available in this layer indicating the source of the change for both non-temporal and temporal changes mapped.
Funding is from the Ministry for Science and Innovation under contract CO9X1101, which was contributed to by the Ministry for the Environment. The Department of Conservation and individual regional councils and territorial authorities have made significant in kind contributions by checking the draft mapping for their areas of interest.
The Chatham Islands, which were available as part of LCDB-2 on a different map projection, have not been re-mapped as part of LCDB v3.0.
