Least-cost Path in GIS Using an Accumulated Cost Surface and Slopelines
Abstract
One of the most interesting and potentially useful applications of geographic information systems is the computation over a mapped space of the fastest, shortest, least-cost, or least-impact routes, given a map of the area with its frictions, costs and impediments. The problem is compared to the refraction of light, and a general solution is discussed, with algorithms to implement these. The problem is broken down into the computation of an accumulated cost surface integrated about a destination, and the generation of slope lines, which are the least-cost paths. Examples are presented from the sport of orinteering.

Least-cost path modeling is a well-established, widely used geospatial modeling technique that identifies the path of least resistance between two or more locations on a landscape, given spatially explicit constraints.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
