Hi there,
I'm a relative newbie to GIS and I'm responsible for a statewide road network (yay for a team of one!). In order to begin to correct a ton of missing to/from address ranges, I'm believe I'm going to have to begin by removing the majority of one city's centerline data and replace it with better, more accurate data.
But since I've never done it and I don't know what I don't know, I'm not sure how to begin or what to watch for. So far, I'm analyzing the attribute tables between the 2 layers and I know how to identify which road segments I want to replace. But I would love some advice on how to go from here, what to watch out for, and how to ensure the ends of the replaced segments snap to the existing segments, so they become one cohesive set again.
I'm running ArcView 10 with Network Analyst (believe it or not), but I've been told I'll be getting upgraded to ArcInfo soon.
Thank you so much!
