[GRASS-user] Re: Import Interlis format

[Patrick S.]

Thanks Andreas,

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?


Regards, Patrick


P.S. sorry for the late answer- but I was off for 2 Weeks
