Dear List,

I have a very large dataset containing about 300.000 polygones which I
would like to import into GRASS using v.in.ogr

Is there a possibility to not build the topology during import, but
afterwards. It runs nor about several hours now and does not provide
more information than 
Importing 300000 map features...

and nothing more. The maschine is very slow in response using the
mouse.

Does anybody have some experience in using this kind of datasets?
Thanks for any suggestions how to import the data.

Best
	Stephan
