NAME

       r.le.trace   -  Displays  the  boundary  of  each r.le patch and shows how the boundary is
       traced, displays the attribute, size, perimeter and shape indices for each patch and saves
       the data in an output file.

KEYWORDS

       raster, landscape structure analysis, patch index

SYNOPSIS

       r.le.trace
       r.le.trace help
       r.le.trace [-pt] map=string  [out=string]   [--verbose]  [--quiet]

   Flags:
       -p
           Include sampling area boundary as perimeter

       -t
           Use 4 neighbor tracing instead of 8 neighbor

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       map=string
           Raster map to be analyzed

       out=string
           Name of output file to store patch data

DESCRIPTION

       The  r.le.trace module can be used to display the boundary of each r.le patch and show how
       the boundary is traced, display the attribute, size, perimeter, and shape indices for each
       patch, and save the data in an output file.

NOTES

       Full instructions can be found in the r.le manual (see "REFERENCES" section below) and the
       r.le.setup help page.
