[GRASS-user] Vector map too big for v.proj

[Kurt Springs]

I am having a problem reprojecting vector maps from lat/long to Irish National Grid.  I have been using v.proj:

v.proj input=Lakes location=IrelandGeo output=Lakes1

and got:

pj_transform() failed: latitude or longitude exceeded limits
ERROR: Error in pj_do_transform

I am fairly sure this means the vector map is too big.  The lat/long maps cover a good deal more than Ireland.  Is their a way to clip what I don't need?  Also, I have a good vector map of the ocean in lat/long, but I only need the part that surounds Ireland.  When I go to clip it, does I have to draw a new bounding box around it and how do I tell it that every thing inside is blue except for the "islands"?

Thanks for any help.
