[GRASS-user] vector area needs water fill

[Kurt Springs]

Hi folks,

I do have another problem I would like some thoughts on.

I have vector areas representing water areas (lakes and oceans).  I  
purchased these areas from the Irish and Northern Irish Ordinance  
Survey.  They came as .dxf packages.  I extracted them but they would  
not fill.  I opened them in v.digit and found that the vector lines  
were broken, even missing in places.  I did my best to close the  
vectors.  The ocean was just a coastline.  I had to modify it by  
attaching a the bounding box and taking away everything that didn't  
look like the ocean.  Getting these areas to fill even though I think  
I managed to join most of the nodes.  Some I think I really did join,  
some I know would not join.

Is there a simple(ish) way to generate areas that will be I can turn  
blue and say "here are the lakes and oceans"?  I don't need them for  
analysis, but I would like to put maps generated into my dissertation  
and have them be pleasing to the eye.

Any help on this will be appreciated.

Kurt
