I'm making routes by selecting links from a streets layer which I export as a new temporarely layer in ArcMap 10.0 with an ArcView/Basic level license. This layer which I call route_temp unfortunately can be very long and contain gaps, for instance when i forget to select very small links which are difficult to see because they are overlaid by other layers. But sometimes the route contains gaps which have to be there because a cluster is in between it. What I would like to be able of is to visiualize all the gaps in the route, so that I can judge myself which gaps have to be filled and which gaps have to stay in the route.
Do you know a tool for this, maybe a field calculator script or something else?
