Hi List,
I'm searching for a way to delineate the perimeter of an area in a
raster map. The area is like the result of r.clump, so it is
caracterized by a integer number in the raster map. I have no problem in
trasforming the raster map in vector with r.to.vect, but the vector is
an area,
v.report map=name option=length units=meters

Or you can add a name for the output file this way:
v.out.ogr -e input=hidr...@permanent dsn=C:/tmp/ olayer=hidro3D

afaik,
it should be:
v.out.ogr -e input=hidr...@permanent dsn=C:/tmp/hidro3D

Recent versions of r.series can calculate arbitrary quantiles.
You may have to make

v.generalize does a great job with simplifying or smoothing lines, but areas

Neither works... Windows Vista has always strange behaviour. I hate it
more and more every day. But not all the profesional software works well

Thx everybody for your help,

Hi,
I'm using v.out.ogr to export GRASS vectors to GMT format. The geometry
exports fine, but the attributes don't seem to be in the GMT file after
the export finishes. I can see the attribute column names in the GMT
header portion of the file, but all I get in the data columns are the x
and y,

It's been proposed that I do some Grass-GIS demonstrations in the demo

So I'm seeking the list's input as to what would make suitable

There are some aspects that may count as constraints that I'd like to
