NAME

r.grow - Generates a raster map layer with contiguous areas grown by one cell.

KEYWORDS

raster

SYNOPSIS

r.grow
r.grow help
r.grow [-q] input=name output=name [radius=float] [metric=string] [old=integer] [new=integer] [--overwrite] [--verbose] [--quiet]

Flags:

-q

Quiet
--overwrite

Allow output files to overwrite existing files
--verbose

Verbose module output
--quiet

Quiet module output

Parameters:

input=name

Name of input raster map
output=name

Name for output raster map
radius=float

Radius of buffer in raster cells
Default: 1.01
metric=string

Metric
Options: euclidian,maximum,manhattan
Default: euclidian
old=integer

Value to write for input cells which are non-NULL (-1 => NULL)
new=integer

Value to write for "grown" cells

DESCRIPTION

r.grow adds cells around the perimeters of all areas in a user-specified raster map layer and stores the output in a new raster map layer. The user can use it to grow by one or more than one cell, or like r.buffer, but with the option of preserving the original cells (similar to combining r.buffer and r.patch).
