Can anyone give me a nutshell explanation of the Geographic Data Files format, or post a few URLs I might find enlightening?
I get the sense (although I'm not sure) that GDF implies building certain topological relationships, frictions, rules, etc into the spatial database. I don't quite get certain facets of what I've been reading so far though. It looks as though the format is mostly relevant to routing-typed applications like pipelines, hydro networks, fleet navigation routing, etc. Is this not something best done with an extension like Network Analyst, or is this something that's done with scripting or programming languages.
Why the "stand alone" environment outside of GIS applications. I can't find anything that's leading to the answers I'm after. Can anyone give me the "for dummies" version? Why would there be any reason to do this "outside" of a GIS environment. From what I've read, it looks as though the final product is delivered in some sort of "textual" framework.
