StructuralC
Summed area (in hectares) of one or more fragments connected by structural corridors (including the area of the corridors connecting them); if there are no fragments connected to the fragment in question, the value of this metric is equal to "fragment size" (see below). In the illustration map below, each cell has 100 m side.
Area (in hectares) of any structurally isolated fragment, of any size, or the area of a fragment connected to another fragment by a structural corridor. Structural corridors are identified as parts of fragments with a width smaller than two times the specified edge depth.
The definition of what is a fragment then depends on the edge depth parameter chosen by the user.
In the illustration map below, each cell has 100 m side and the edge depth was chosen as 50 m.
Area of habitat that is structurally (contiguously) connected to a fragment. In practice, it is the difference (in hectares) between the Patch size and the Fragment size metrics; when a patch has only one fragment, its structural connectivity will be zero.
The definition of this metric depends on what is a fragment and a structural corridor, so it also depends on the edge depth parameter chosen by the user.
In the illustration map below, each cell has 100 m side and the edge depth was chosen as 50 m.
Proportion of the target landscape class (habitat or another class(es) of interest, the one represented by the value 1 in the input binary map) within a given window around each map cell.
It depends on the size of the window chosen by the user.
The user must decide which window size will be used to calculate metrics. It corresponds to search extent from each pixel where the calculations will be applied. It can be based on the extent of landscape perception of the target species, process or groups analyzed. It is given in meters.
