This Movement Cost Surface (raster) is an intermediary modeling product that was produced by the Linkage Mapper tool (McRae and Kavanagh 2011) in the process of developing Least-Cost Paths (LCPs) and Least-Cost Corridors for use in our coastal marten connectivity model. It is derived from two other datasets (ResistanceSurface and PrimaryModel_HabitatCores) and was produced using the Linkage Mapper parameters defined in the Lineage section of the geospatial metadata record. More specifically, this is an intermediary product in which the resistance surface and habitat cores have been converted into a movement cost surface to show the accumulative movement cost (in cost-weighted meters) of moving away from each core. The easiest way to understand where this intermediary dataset fits into the broader Linkage Mapper modeling process is to review the Linkage Mapper User Guide, available on circuitscape.org (McRae and Kavanagh 2016). Refer to the PrimaryModel_LeastCostCorridors, ResistanceSurface, and PrimaryModel_HabitatCores metadata records for additional context.
