Determining The Optimal Route For A Transmission Line Using Least Cost Arcgis geoprocessing tool that calculates the sum of two accumulative cost distance rasters with the option to apply a threshold based on percentage or accumulative cost. Whether you are interested in creating wildlife corridors, proposing a new hiking trail, or siting a transmission line, the new least cost corridor tool is a powerful addition to distance analysis workflows.
Gis Nouveau Corridor Cost Path Analysis Possible movement of something as unpredictable as a wild animal can never be definitively plotted, but expanding a possible path into a corridor, with placement based on measurable factors, can provide a useful predictive tool. The least cost corridor tool takes the sum of the two input accumulative cost rasters and recreates the ideal least cost path between source 1 and 2 from the minimum value in the corridor raster. To create a corridor, two cost accumulative rasters must be created using a cost distance tool (cost distance or path distance, for example), one for each source (or set of sources). the diagrams below show the cost surfaces being created from a single cell location for demonstration purposes.

Least cost path analysis can be expanded to corridor analysis. instead of resulting in a single base solution represented by a polyline, corridor analysis produces multiple solutions, representing a zone where costs are close to the least cost. In this post i'll demonstrate how to create least cost paths using qgis and grass gis, and in doing so will describe how a cost surface is constructed. in a surface analysis, you model movement across a grid whose values represent friction encountered in moving across it. It combines multiple routing algorithms, including the least cost path, to evaluate and propose potential corridors for transmission lines. this process takes into account engineering constraints, environmental impacts, and financial considerations. The least cost path (lpc) method for determining the optimal route and corridor is a well established grid based gis technique. the optimal route indicates the best connection between starting and ending locations.
