Hello all, I built corridors between core forests using the "Linkage mapper"(https://circuitscape.org/linkagemapper/) which is a tool that could be used in ArcGIS. But the final corridor image is a raster file with values based on the eqaution: Normlaised least cost corridor value = Cost weighted distance from core forest A + Cost weighted distance from core forest B - COst weighted distance accumlated moving along the ideal path (least cost path) connecting the core forests A and B. I wanted to limit the width of corridors using some simple logic but since the values in the corridor raster is based on the above equation i find it hard to limit the width. Could someone explain this equation and how is it formulated. Thank you, Maya
