<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>This erosion type mapping was carried out on-screen using the 10 cm digital orthophotography supported by visual terrain analysis using the LiDAR DEM (hill shade and slope classification). The orthophotos were used to identify the most recent erosion features in the Kaikohe<br>
study area; the DEM aided the mapping of features not visible in the orthophotos due to age<br>
or vegetation cover. </p>
<p>The classification of erosion types followed the categories defined by the Land Use<br>
Capability Survey Handbook (Lynn et al. 2009), which differentiates between surface<br>
erosion, mass movement, fluvial erosion, and deposition. Note that the estimated depth of the<br>
landslides (s = shallow, d = deep) was not consistently recorded; instead, the area of the<br>
landslides serves as a reasonable proxy. </p>
