[GRASS-user] Merge parallel roads

[Hendrik Hoeth]

Hi,

I need to merge parallel roads, like highway lanes, into one. I've
looked around a bit and found solutions for ArcGIS ("Collapse Dual Lines
To Centerline") and for OSM XML files (Skeletron), but nothing that
works straight in GRASS. What's the best way of doing this in GRASS? 

Cheers,

    Hendrik
