pij* = perimeter of patch ij in terms of number of cell surfaces. aij* = area of patch ij in terms of number of cells. Z = total number of cells in the landscape. |
| Description | COHESION equals 1 minus the sum of patch perimeter (in terms of number of cells) divided by the sum of patch perimeter times the square root of patch area (in terms of number of cells) for all patches in the landscape, divided by 1 minus 1 over the square root of the total number of cells in the landscape, multiplied by 100 to convert to a percentage. Note, total landscape area (Z) excludes any internal background present. |
| Units | None |
| Range | The behavior of this metric at the landscape level has not yet been evaluated. |
| Comments | Patch cohesion index at the class level measures the physical connectedness of the corresponding patch type. However, at the landscape level, the behavior of this metric has not yet been evaluated. |
