Dear all,
I have a raster map where each patch (i.e. forest fragment) have different
ID.
I need to estimate the perimeter per patch, but R.le.patch can't do the job.
------------
GRASS 6.4> r.le.patch map=fragments sam=w per=p1 siz=s1 out=STATS.txt
PARAMETER CHOICES:
MAP: fragments
SAMPLE: whole map TRACING: 8 neighbor
SIZE MEASURES:
mean patch size
PERIMETER MEASURES:
sum of perims
R.LE.PATCH IS WORKING....;
ERROR: G_calloc: unable to allocate 24806 * 8 bytes at alloc_cell.c:83
------------
Any hint?
