I'd like to calculate least cost paths between fragments using a cost raster I created based on habitat suitability values.
I saw that most people use Linkage Mapper, but I don't have access to ArcGIS. I also saw the gdistance function, but it is based on a DEM and I'd rather use my cost layer.
Is there an open source alternative to Linkage Mapper? Or can it be used without ArcGIS?
