Trafficability analysis

General info
1/100 000 to 1/25 000
Spatial resolution: 
30 to 10m
Required processing: 
Correction and smoothing of DEM, wathershed calculation, compute Cost Surface Raster with map algebra techniques, launch least-cost path script (CPU time consuming)
Data requirements: 

Digital Elevation Model (DEM) and indicator points.

Most effective routes across a given area used to reconstruct former battleground theatres.

Why using remote sensors?: 

A trafficability analysis measures the cost of a person/vehicle to pass through a specified terrain in terms of time and effort, and could determine the most probable accessible route among some given locations.
