v.build.polylines
A more complicated alternative which I used with great success before
finding v.build.polylines is with the join_cst matlab script, available here: http://sea-mat.whoi.edu/mapstuff-html/
(Octave should work if you don't have Matlab)
When I type r.report command to abtain an area data,
it gives me 0.623 km^2.
But I know this area was above 500 km^2.
Please tell me where is my problem are?
my steps doing this was:
1. make a UTM location and mapset
2. r.in.bin to import Landsat image.
3. r.digit to make an area which surrounds my area.
4. r.report
Thank you a lot.

My obtained data (only one lake) through command r.report was still small
than real data.
Thank you to any of your advice.

r.report will only report on the current region (display monitor). For
the full map data you have to zoom to the extent of the map.
