Stock Exclusion Low Slope Land 2022
The Stock Exclusion Low Slope Land 2022 layer identifies areas of "Low Slope Land" as defined in the Resource Management (Stock Exclusion) Regulations 2020. The layer shows land with a local slope of less than or equal to 5 degrees where beef cattle and deer are required to be excluded from waterways. Areas of lakes, ponds, settlements, urban parkland, transport infrastructure and estuarine open water, as defined in Land Cover Database 5, are excluded. Areas over 500m in altitude are also excluded. This layer replaces the Stock Exclusion Low Slope Land 2020 layer.
This layer defines the Low Slope Land area referred to in the Resource Management (Stock Exclusion) Regulations 2020.

The general steps in the geo-processing methodology to create this dataset were as follows:
1. Starting with LCDB5, an exclusion layer of the built-up areas, open parkland, transport infrastructure, lakes and ponds and estuarine open water was created (LCDB5 exclusion layer).
2. A 500m height mask was created from the Manaaki Whenua - Landcare Research 15 Digital Elevation Model (500m Mask).
3. The slope layer was calculated in degrees from the MWLR DEM using ERDAS Imagine.
4. The slope layer was thresholded to 5 degrees and majority filtered with a 3x3 filter.
5. The resulting slope layer was smoothed and simplified.
6. LCDB5 exclusion layer and 500m Mask were erased from this slope layer.
7. Polygons under 2 hectares were deleted, along with polygons that did not intersect, or were within 5m of, a REC 2 river reach.
