aijc = core area (m2) of patch ij based on specified edge depths (m). |
| Description | TCA equals the sum of the core areas of each patch (m2) of the corresponding patch type, divided by 10,000 (to convert to hectares). |
| Units | Hectares |
| Range | TCA ≥ 0, without limit. TCA = 0 when every location within each patch of the corresponding patch type is within the specified depth-of-edge distance(s) from the patch perimeters. TCA approaches total class area (CA) as the specified depth-of-edge distance(s) decreases and as patch shapes are simplified. |
| Comments | Total core area is defined the same as core area (CORE) at the patch level (see Core Area), but here core area is aggregated (summed) over all patches of the corresponding patch type. |
