# Least Cost Paths

O. Conrad, V. Olaya, V. Wichmann (c) 2004-2010
This module allows to compute least cost path profile(s). It takes an accumulated cost surface grid and a point shapefile as input. Each point in the shapefile represents a source for which the least cost path is calculated.
In case the point shapefile has more than one source point defined, a separate least cost path is calculated for each point. The module outputs a point and a line shapefile for each least cost path.
The module allows for optional input grids. The cell values of these grids along the least cost path are written to the outputs as additional table fields.
