I need some suggestions, let's see:
I have two heavy polyline datasets, from different sources, so they will never be coincident (it doesn't matter this issue). Both have the same field from which I need to work. These string fields has 3 possible values. So, I need to check if every polyline, which is more or less parallel to the other, is coincident in VALUE.
We've got 5 labelled (with the Value to check) polylines (3 from one dataset, 2 from the other), in this cases, there is no mistakes, there is concordance. Then I have a 1 polyline (the one with the red cross), with no paired polyline, but this doesn't really care. Just the ones paired mostly parallel.
Somebody knows any ArcGIS10 tool or some Python code to check it?
