Patch Accounts

Adding 'patching' to your Patchworks model can add a valuable spatial objective to your analysis. Patch accounts model the distribution of patches of various sizes (in terms of area or frequency) over the landscape. Generally, a patch is defined as a connected set of topologically adjacent polygons, with all polygons in the set having a value for a specified patch membership criterion attribute that is greater than a specified threshold level. This section will explain what a patch criteria attribute is, how to define patch accounts and size classes, how to add these accounts to the PIN file and a brief explanation of the patch sub-account types.
