Basically I have this shape file of road data from TIGER data repo and I use arcscan to trace vector data from an image to get a shape file and I need to find out how good these lines from the scanned shapefile match with the road data from TIGER.
The problem is with the Polyline matching - the extents of the polylines in the TIGER data and the scanned shapefile are not the same. Please look at the attachment to get an idea of what I mean. [ATTACH=CONFIG]12649[/ATTACH]
So here are my questions -
> I try to run the Analysis Tools>Proximity>Near on the two shape files to find how good they match but the results are extremely poor. Is that the tool for this purpose?
> I tried 'Splitting' the polylines from the arcscanned shapefile - the only useable option over there was the 'm-way equal split' that too it has a maximum limit of 99 segments. The best option would have been a distance repeatable split (eg. split every 20 miles) but there is no option. The option closest to that is the distance split at the start or end of the polyline. Is there any other option I'm overlooking?
> The only other option that I see right now is to extract the coordinates of the polylines from both the shapefiles and write a custom code to handle it using the end and the mid coordinates and some bounding box logic!
What would you advise? Suggestions?
Thanks!!
