Fragmentation Classes from Density and Connectivity


Description

Fragmentation classes: (1) interior, if Density = 1.0 (2) undetermined, if Density > 0.6 and Density = Connectivity (3) perforated, if Density > 0.6 and Density - Connectivity > 0 (4) edge, if Density > 0.6 and Density - Connectivity < 0 (5) transitional, if 0.4 < Density < 0.6 (6) patch, if Density < 0.4
