This dataset was first added to LRIS Portal on 19 Jul 2012.

This data set is a mask of the temporal and non temporal changes made between land cover database v3.0 and the previous version (land cover database-2). The non-temporal changes include errors in the earlier mappings, step artefact removal, and coastline adjustments. Note: the non-temporal attribute is named "NoTemporal" due to a character length limitation.

An “authority” attribute is also available in this layer indicating the source of the change for both non-temporal and temporal changes mapped. The Authority attribute indicates who identified the change, where;

1 = Landcare Research.
2 = Regional Council or Territorial Authority.
3 = Department of Conservation.

This layer was produced with a map tolerance of 10cm.

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.

This dataset was first added to LRIS Portal on 13 Nov 2013.

This data set (LCDB v3.3 Change) is a mask of non temporal changes made between LCDB v3.3 and the previous version (LCDB v3.0) and temporal change between the 2001 and 2008 timesteps. The non-temporal changes include errors in the earlier mappings and linework refinement, including reversal of over-smoothed hand-drawn linework in v3.0. Errors were identified from; a review of low producing grassland in the South Island, updates from MfE's Kyoto Land Use maps, checks of the dating of v3.0 mapped change, and feedback from users. An “EditDate” and “Authority” attribute are available in this layer indicating the date and source of the change for both non-temporal and temporal changes mapped. The Authority attribute indicates who (or who's dataset) identified the change. Note, where minor line-work improvements were applied using automated processes, the EditDate and Authorify have not been changed (but the “NonTemporal” attribute is still set true). This layer was produced with a tolerance of 50cm as a zero tolerance generates slivers too small for the portal software to project correctly. 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.

DEPRECATED - THIS VERSION WAS SUPERCEDED FIRST BY VERSION 3.3 AND MORE RECENTLY BY VERSION 4.0 now available at lris.scinfo.org.nz/layer/412-lcdb-v40-land-cover-d...

This database is a thematic classification of land cover and land use classes. The current version 3 contains 33 classes designed to be compatible with earlier 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. The land cover database 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 land cover database 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 (land cover database 2). This document is available as an attachment to this dataset (see below), and on the land cover database project site (www.lcdb.scinfo.org.nz).

The land cover database 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 land cover database 2 and land cover database 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 land cover database2 on a different map projection, have not been re-mapped as part of land cover database v3.0.
