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

   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.
