v.costdist.mat is a GRASS script (i.e., a bash script to be executed under a GRASS console, or from a GRASS GUI) for computing cost-based distance matrices.

Uses GRASS' r.cost iteratively to compute minimum-cost distances between two or more sets of points.

NAME

v.costdist.mat - Cost-based distances between points

SYNOPSIS

v.costdist.mat\

v.costdist.mat help\

v.costdist.mat [-k] from=filename to=filename[,filename,...] cost=filename [--verbose] [--quiet]

Flags:

-k : Use the 'Knight's move'. Forwarded to r.cost (see r.cost).

--verbose : Verbose module output

--quiet : Quiet module output

Parameters:

from=filename : Name of existing vector points map

to=filename[,filename,...] : Name(s) of existing vector points map(s) where cost-distances to "from" points are to be stored

cost=filename : Name of existing raster file containing cost information
