I'm sorry to interrupt Your advanced discussion, but if there are just
some "holes" that are required to be converted to polygons, then why

new tools in the last month (including a new OS, ubuntu) and got up and
running very fast because of help received here. Thank you again!
Second--another question (of course). I have a vector (polygon) layer
and th
