[Freegis-list] polygonize a set of lines

[Eduardo Patto Kanegae]

Hi folks,

I have a CAD line layer describing the limits of a soil map. It's a
line layer because the first need was for printing only.

Now I need to put this soil map as a polygon into a GIS dataset.

Does anybody recommend any free gis tool that could be usefull to do that?

thanks
