<br /><strong>Updated with new data on 13 Dec 2023</strong><br />
<p>Maps produced for MethaneSAT. Each dataset is an estimate of methane produced by enteric fermentation across different classes of livestock at approximately 1.5 km resolution (pixel length); this is not an equal area projection. Datasets are 12-band raster data where each band is monthly emissions (1=January). "CCTO", "CCPO" and "CCAV" refer to values of livestock carrying capacity determined by the <a href="https://lris.scinfo.org.nz/layer/48076-nzlri-land-use-capability-2021/">NZLRI</a>.</p>
<p></p>
<p>The data underlying these maps are livestock distribution maps at sub-farm scale. Methane emissions are estimates based on Tier 2 inventory accounting methods. Distributions of livestock are determined through a process that combines <a href="https://lris.scinfo.org.nz/layer/106519-agribase-november-2021/">Agribase farm counts</a>, <a href="https://lris.scinfo.org.nz/layer/105112-north-island-national-pasture-productivity/">pasture productivity</a> and the <a href="https://www.stats.govt.nz/help-with-surveys/list-of-stats-nz-surveys/about-the-agricultural-production-survey/">agricultural production surveys and census</a>.</p>
<p></p>
<p>A slightly more detailed methodology document is included as an attachment.</p>
<p></p>
<p>Note that the output is considerably downsampled from sub-farm scale, using a weighted sum algorithm. This is both by necessity (to sufficiently confidentialise Agribase information), and by design (to match the resolution used in inverse modelling).</p>
<p></p>
<p>Units are kT CH₄ (kilotonnes of methane), monthly total per pixel.</p>
<p></p>
<p>Please acknowledge the funding from the NZ Space Agency through the MethaneSAT Project (C01X2023) which ultimately made this possible.</p>

<br /><strong>Updated with new data on 20 Dec 2021</strong><br />
<p>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 It comprises two sets of data compiled using stereo aerial photography, published and unpublished reference material, and extensive field work:</p>
<ol>
<li>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. </li>
<li>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.</li>
</ol>
<p>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.</p>
<p>Update of Edition 3 NZLRI. This update involves ++<strong>no new mapping</strong>++, but does include a ++<strong>new National Land Use Capability legend</strong>++ correlated for all regions across New Zealand. Attributes include original LUC units codes and unit descriptions so that users more familiar with original regional codes and North Island correlations can track the pedigree of units from old to new codes and descriptions.</p>

<p>This dataset is the land inventory and Land use capability output from the MPI SLMACC Northland project. It is derived from raster data through a series of modelling steps based on field data collected at over 400 observation points. Raster maps are then subjected to segmentation processing to create polygons that are assigned inventory attribute values based on zonal statistics from the original raster datasets. The majority of mapping is carried out by automated processing, the exceptions currently being erosion mapping and parent material (because of scale of available source information). Forestry 300 Index and Net Profit data is derived from modelled surfaces provided by SCION. Land Use Capability is assigned according to a set of rules defined by an expert. </p>

<p>A 25m grid of BASE carrying capacity for ALL leases (original model for all lease properties). This layer is buffered around the lease boundaries supplied by LINZ by roughly 5km to ensure that it can be reused for analysis where property boundaries are found to be incorrectly mapped or out-of-date.</p>
