[GRASS-user] Water Polygon Issue

[Ryan Rosario]

I believe the file contains closed lines, or that is the way they appear on
the screen.

I was able to color the polygon after using v.type and v.centroids, but now
I have another problem. I am using this water polygon to hide the part of
the Pacific Ocean displayed as part of the county, so I don't want to
display the lines. If I disable "Draw lines" the outline is replaced with a
bunch of small broken line segments. I don't want to display any lines at
all, just a blank polygon that will cover the ocean. Is this where I would
use the v.clean script?

Thanks again,
Ryan
