Least Cost Pathway Analysis

  • 3D view of pathways between Europe & UK based on the General Bathymetric Chart of the Oceans; elevations x 200. Use mouse controls  to manoeuvre &  the controls top right to set the flood plane at -32 (easier done by typing in the number). It is apparent that with rising sea levels, the northern route would be more important by 9,000 BP.
Frachetti et al 2017 report an additional technique for simulating the optimal pathways of migrating herds at 750 m to 4,000 m elevation by using remote satellite images & the normalised vegetation index.
