I'm new to GIS and I'm asking this a bit out of desperation, but I'm trying my best not to get overwhelmed. :)
I want to download a file that contains data of a road network (of what road network is not a concern to me), visualize this road network, but then be able to run a simulation on it (so it can't be an image, i.e. a .jpeg). I'm looking for what resources/software I should use.
(Is there a way I can chat with someone who knows about GIS? I feel that would be better.)
