[GRASS-user] newbie vector question

just starting with vectors, to try out DGlib routing, and I'm a little unclear on the Postgis concepts here...

I guess the general sequence is to import all the geometry into GRASS binary, and then link back to the attributes? I'm coming at this with a just a few (million) street segments...

thanks in advance!

hmmm - diving into dglib stand-alone example sources, looks like it wants to read everything into memory and build very interesting structs, which is totally understandable...so I can see where it would be a good idea to dump link/node info from PostGIS before going wild through the data...(as opposed to a billion SQL calls)
