On- and Off-road Emergency Response (Least Cost Path) …like a raindrop, the “Steepest Downhill Path” identifies the optimal route (Quickest Path) as it traces the shortest but not-necessarily-straight route the accumulated travel-time wavefront took in reaching the end location. Optimal Path draped over 3D Travel-time Surface Optimal Path superimposed on 2D Road Map HQ Road = 19 min ATV = 15 min Hiking = 62 min 96 min This procedure, termed Least Cost Path analysis, is a generalized map-ematical technique that can be applied to most routing applications. For example, in routing a proposed electric transmission line, 1) engineering, environmental, legal, land use, political and other information are translated into absolute and relative costs (suitability of conditions), then 2) an accumulated cost surface is generated, and finally 3) the optimal path identified. Identifying all of the nearly optimal paths (Nth optimal paths) generates a Least Cost Corridor of best locations for identifying and assessing alternative routes. (Berry)
