No I'm not marking individual paddies.  Maybe my message was a bit confusing.
The SPOT5 has a pix res of 10 meters.  I usually map a farm polygon
when there is obvious subdivision between adjacent farms like large
irrigation canals.  This is usually visible in the image at around 4-5
pixels (roughly 40-50 meters).  The gap size seems sensible enough.

Whenever possible, I am also excluding residential areas around the farms.

Is this OK?

Sorry I can't provide a visual example (the data is on another
machine) and I haven't added anything in the OSM database just yet.
