<p>The New Zealand Land Cover Database (LCDB) is a multi-temporal digital thematic map of land cover and land use. Land cover at each of four periods; summer 1996/97, summer 2001/02, summer 2008/09, and summer 20012/13, is both delineated and classified. The land cover classification evolved over the first three periods but compatibility has been maintained. The current version, LCDB v4 (and its predecessor LCDB v3), contains 33 classes. The classification used in LCDB v3 and v4 can be found in the document LCDB2-3CorrelationTable.pdf along with the correlation from the classification used in the earlier version (LCDB v2). This document is available as an attachment to this dataset in the LRIS portal (<a href="https://lris.scinfo.org.nz/">lris.scinfo.org.nz/</a>), and on the LCDB project site (<a href="http://www.lcdb.scinfo.org.nz">www.lcdb.scinfo.org.nz</a>). The LCDB was designed to be compatible in scale and accuracy with Land Information New Zealand’s 1:50,000 topographic database. The LCDB is intended for use in areas such as state of environmental monitoring, forest and shrub inventory, biodiversity assessment, trend analysis and infrastructure planning. LCDB v4.0 was released in June 2014 and includes non-temporal edits to the 1996/97, 2001/02, and 2008/09 time periods along with new mapping of change up to the summer 2012/13 period. A change layer, “LCDB v4.0 change” is available to indicate both non-temporal and temporal changes made between LCDB v3.3 and LVCDB v4.0, The non-temporal changes include error in earlier mapping. An “authority” attribute is also available in this layer acknowledging the source of the latest mapping of both non-temporal and temporal change. The Chatham Islands, which were available as part of LCDB-2 on a different map projection, have not yet been re-mapped in LCDB v3.0, v3.3, or v4.0.The data is referenced to the New Zealand Transverse Mercator 2000 projection (NZTM2000) which uses the NZ Geodetic Datum 2000 (NZGD2000). Errors in the data due to misclassification (not changes since mapping) or poor delineation can be reported to Landcare Research for inclusion in the next release using the online feedback mechanisms in <a href="https://lris.scinfo.org.nz/">lris.scinfo.org.nz/</a>.</p>

<p>DEPRECATED - THIS VERSION HAS BEEN SUPERCEDED BY VERSION 4.0 which is now available at <a href="https://lris.scinfo.org.nz/layer/412-lcdb-v40-land-cover-database-version-40/">lris.scinfo.org.nz/layer/412-lcdb-v40-land-cover-d...</a>. </p>
<p>The New Zealand Land Cover Database (LCDB) is a thematic classification of land cover. The current version LCDB3.3 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 LCDB3.3 can be found in the document LCDB2-3 CorrelationTable.pdf along with the mapping from the class set used in the previous version (LCDB2). This document is available as an attachment to this dataset in the LRIS portal (<a href="http://www.lcdb.scinfo.org.nz/">www.lcdb.scinfo.org.nz/</a>) and on the LCDB project site (<a href="http://www.lcdb.scinfo.org.nz">www.lcdb.scinfo.org.nz</a>). LCDB3.3 was released in August 2013 and includes corrections to all time steps 1997/97, 2001/02 and 2008/09. In particular, it incorporates edits arising from user feedback, a review of improvements to low producing grasslands in the South Island, updates to croplands from Kyoto Land Use mapping, and corrections to the dating of land cover change mapped in LCDB3.0. “EditAuthority” and "EditDate" attributes are maintained in this layer to indicate the source of the change for both non-temporal and temporal changes mapped.The Chatham Islands, which were available as part of LCDB-2 on a different map projection, have not yet been re-mapped as part of LCDB3.</p>

<p>The New Zealand Land Cover Database (LCDB) is a multi-temporal, thematic classification of New Zealand's land cover. It contains 33 mainland classes (35 including the offshore Chatham Islands). The classification has evolved from version to version but backward compatibility has been maintained. Geographic features are described by a polygon boundary, a land cover code, and a land cover name at each of four nominal time steps; summer 1996/97, summer 2001/02, summer 2008/09, and summer 2012/13. The data set is designed to complement in theme, scale and accuracy, Land Information New Zealand’s 1:50,000 topographic database. LCDB is suitable for use in national and regional state-of-environment monitoring, forest and shrubland inventory, biodiversity assessment, trend analysis and infrastructure planning. The classification used in LCDB v4.1 is presented in the document 'LCDBClassesAtVersion4.1.pdf' and a table correlating LCDB classes over all four LCDB versions is presented in the document 'LCDBClassCorrelations.pdf'. Both of these documents are available as an attachment to this dataset in the LRIS portal (<a href="https://lris.scinfo.org.nz/">lris.scinfo.org.nz/</a>) and on the LCDB project site (<a href="http://www.lcdb.scinfo.org.nz">www.lcdb.scinfo.org.nz</a>). LCDB v4.1 was released in July 2015 and includes corrections to all time steps 1996/97, 2001/02, 2008/09 and 2012/13. A description of work undertaken for this release (including that in all earlier releases) is presented in the Lineage section. Of particular note at 4.1 is the re-mapping of Chatham Islands - first mapped at version 2, but then not continued through versions 3.0, 3.3, and 4.0 because of resource constraints. “EditAuthority” and "EditDate" are attributes, maintained since version 3.0 to indicate authorship and nominal date of polygon mapping, edit or change. The data is referenced to the Chatham Islands Transverse Mercator 2000 projection (CITM2000) which uses the NZ Geodetic Datum 2000 (NZGD2000). Errors in the data due to misclassification (not changes since mapping) or poor delineation can be reported to Landcare Research for inclusion in the next release using the online feedback mechanisms in <a href="https://lris.scinfo.org.nz/">lris.scinfo.org.nz/</a>.</p>

<br /><strong>Updated with new data on 16 Jul 2015</strong><br />
<p>This data set (LCDB v4.1 Version Trace) allows users to track changes back to the previous version (v4.0), 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. </p>
<p>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. </p>
<p>Similar datasets were provided to trace LCDB2 ==> LCDB v3.0, LCDB v3.0 ==> LCDB v3.3, and LCDB v3.3 ==> LCDB v4.0. Note however, we previously called the dataset "Change" rather than "Version Trace", e.g. "LCDB v4.0 Change".</p>
