I'm trying to vectorize a raster image of a highway in ArcGIS Pro. In ArcMap, ArcScan easily does the trick, but ArcGIS Pro doesn't have ArcScan. When I try Raster to Polyline, ArcGIS creates an enclosed polyline to represent each and every pixel making up the highway. When I try Raster to Polygon, ArcGIS creates two vectors, one to represent each side of the highway line, instead of just one vector to represent the highway itself. I assume this is because the raster line making up the highway is several pixels thick, so it's recognized as representing a 2D object instead of a line.
I've tried making the highway line thinner, but am not licensed to use the Thin tool. Does anyone know how to vectorize a (thick) raster line in ArcGIS Pro? Thanks so much!
Hi ndarner,
Have you tried Polygon To Centerline tool?
I used for converting river polygons and it worked alright for me.
Cheers.
