I need to know how to create roads vector center lines from raster using ArcGIS. I have tried to use Iso Cluster Unsupervised classification tool to classify raster and set it to 30 classes. After that Reclassify tool to filter the roads cells from other values. After that I have used "Raster to polyline" tool and checked the Simplify box, but the results are a lot of lines looking like a polygons (screenshot). I need it to be just one road center line. This is a classic topographic map and I have a lot of roads to process so this can`t be a semi-manual process, I need it automatically as much as that is possible.
Does anyone know better way to solve my problem?
