The New Zealand Land Resource Inventory (NZLRI) is a national database of physical land resource information. It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work:

  1. An inventory of five physical factors (rock type, soil, slope, present type and severity of erosion, and vegetation). A 'homogeneous unit area' approach is used to record the five physical factors simultaneously to a level of detail appropriate for presentation at a scale of 1:50,000.

  2. A Land Use Capability (LUC) rating of the ability of each polygon to sustain agricultural production, based on an assessment of the inventory factors above, climate, the effects of past land use, and the potential for erosion. The NZLRI covers the country in 11 regions, each with a separate LUC classification.

The first edition NZLRI provides national coverage from mapping between 1973 and 1979 at a scale of 1:63,360. A limited revision regional upgrade of the north Waikato area was completed at a scale of 1:63,360 in 1983. Second edition NZLRI regional upgrades at a scale of 1:50,000 have been completed for Northland, Wellington, Marlborough and Gisborne-East Cape. Third edition NZLRI layers contained a restructured polygon attribute table to allow the core NZLRI to complement the newly created fundamental soil layers with minimal duplication

The soil fundamental data layers (FDLs) contain spatial information for 16 key attributes, each of which is measurable (i.e. is given a numeric value rather than being assigned to a descriptive class or category) and is recorded in appropriate units of measure. Since attributes have measurable values, FDLs are particularly useful in computer modelling and have enabled researchers and resource management decision-makers to make the most of rapid developments in GIS technology. Key soil attributes were selected through a consultation process with stakeholders, and generally fall into three groups: soil fertility/toxicity, soil physical properties (particularly those related to soil moisture), and topography/climate (T). Parameters include slope, potential rooting depth, topsoil gravel content, proportion of rock outcrop, pH, salinity, cation exchange capacity, total carbon, phosphorus retention, flood interval, soil temperature, total profile available water, profile readily available water, drainage, and macropores (shallow and deep).

Regional soil databases were the key to generating FDLs. New Zealand was subdivided into several geographic regions and soil scientists were allocated a region for which they developed a ‘regional legend’, i.e. database. Regional data were correlated using the New Zealand Soil Classification (NZSC), referenced to the National Soils Database (NSD) and other relevant data sources, and then linked to the soil polygons in the New Zealand Land Resource Inventory (NZLRI). This layer holds the NZSC data upon which the remaining FSLs were based.

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 (lris.scinfo.org.nz/) and on the LCDB project site (www.lcdb.scinfo.org.nz). 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 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 lris.scinfo.org.nz/.

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 (lris.scinfo.org.nz/), and on the LCDB project site (www.lcdb.scinfo.org.nz). 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 lris.scinfo.org.nz/.

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.

This dataset was last updated on LRIS Portal on 18 Oct 2011.

This database describes the soils of the pastoral and cropping land of Canterbury, from the Kowhai River in the north to the Rangitata River in the south, but not including Banks Peninsula. The original survey was mapped as a reconnaissance soil survey at 2 miles to the inch. These original soil boundaries have been very substantially revised and recompiled onto 1:50,000 scale topographic base by T.H. Webb in the 1990s and again in the 2000s.

NOTE: There has been a change in the way the S-map is being made available to users. The S-map primary map layer of soil classes (i.e. delineated areas that are labelled with the soil family name) is no longer freely available to commercial users. Access to this data and associated soil attribute data for commercial use is by negotiation - contact Graeme Anderson (andersong@landcareresearch.co.nz).

ACCESS to publically available S-map data is now at

S-map Soil Depth

S-map Soil Drainage

S-map Soil Texture

S-map's primary map layer is soil classes, i.e. delineated areas that are labelled with the soil family name. Each soil family is defined as a unique combination of attributes (NZSC classification, parent material, rock type, dominant texture and permeability class). Soil classes are further characterised as siblings according to their depth to rock class, stoniness, land type, drainage, texture (more detailed), functional horizons and miscellaneous variant information. The uncertainty of each of these family and sibling attribute classes is specified. Associated with the soil class layer will be additional map layers of fundamental and derived soil properties. The fundamental soil properties are depth (diggability), depth to slowly permeable layer, rooting depth, rooting barrier, horizon thickness, stoniness, clay and sand content. They are developed from sample information and expert knowledge. The derived soil layers are each based on a model (or pedo-transfer function). Some models are simple lookup tables that depend only on the soil class. Others combine various soil, land use, vegetation, climate or topographic attributes in a mathematical formula. Derived layers will include available water (mm), macroporosity, water retention, bulk density, total carbon, total nitrogen, phosphorus, calcium, cation exchange capacity, pH, and phosphorus retention.
