To facilitate interpretation of the algorithm, we intentionally separate from each equation any constants used to rescale the metric. These conversion factors are separated out by parentheses even though they may be factored into the equation differently in the computational form of the algorithm. For each metric, the mathematical formula is described in narrative terms to facilitate interpretation of the formula. The button will allow you to hyperlink directly to the Metrics List document. The next field in the patch output file is patch attribute lookup item.
CORE approaches AREA as the specified edge distance decreases and as patch shape is simplified.
CAI approaches 100 when the patch, because of size, shape, and edge width, contains mostly core area. Note, when the search buffer extends beyond the landscape boundary, only patches contained within the landscape are considered in the computations.
