I have a fairly large Polyline layer of Highway Ramps that has a high amount of linework errors (missing segments) that are showing up in the ESRI Base Map Imagery layer. Instead of manually comparing the Polyline (ramps) layer against the Raster layer), I was thinking of converting the Raster layer into Polylines, extracting ramps from this polyline layer, and then comparing the new Polyline layer against my ramps layer to indicate where the missing ramps are.
When I was doing Raster-Polyline, I was guessing working with Environment Settings might help but I didn't see anything that would help classify the types of routes in the imagery into polylines (i.e., roads versus ramps).
Is there a way to extract types of segments from a Raster-Polyline layer?
(If you wanted to play with this, think of how Image Classification gives us a Number of Bands (R,G, and B); why not have a number of types of features of certain feature classes?. i.e., Polylines: Highways, Ramps, Streets)
Thanks.
