<h1 class='module'>Least Cost Paths</h1>
|
|
<div class='author'>O. Conrad, V. Olaya, V. Wichmann (c) 2004-2010</div>
|
|
<div class='description'>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.<br/>
|
|
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.<br/>
|
|
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.<br/>
