[GRASS-user] unwanted 0_polygon import

[Barbosa, A. Marcia]

Hi all,

I'm importing species distribution shapefiles into GRASS via QuantumGIS (using the GRASS shell), but enclosed areas that are supposed to be holes are imported as a 0_polygon. So, instead of the original ring polygon, GRASS imports gives me a 0_polygon inside of a 1_polygon. How can I turn these 0_polygons into holes (in a lot of vector maps simultaneously), or import only the 1_polygon(s) as rings?

Cheers,
Marcia
