I'm trying to build a network data set using Open Street Map data to use for location/allocation modeling for a large portion of Northern California. Things are going pretty well, but I'm having one problem. There are various areas that contain road segments that do not connect to any other road segment in the data set. Is there any way to detect and remove these segments? I've tried looking at the geodatabase topology tools, but couldn't find a tool that matched the context, particularly because some of these "floating" roads are composed of multiple polylines. Any ideas?
