[GRASS-user] Re: Import Interlis format

But it just doesn't seem a right approach to me to convert a topological
format into a simple feature format to import it to GRASS. I am speaking
of some 300.000 polygons of buildings and X00.0000 parcels, which
created a lot of topological problems when I imported from shapefiles.
That's why I did ask the dataowner for the INTERLIS format.
Isn't there any other solution or exchange format that is topological?
P.S. sorry for the late answer- but I was off for 2 Weeks
