I have raster data representing urbanized areas, which I'd like to trace and convert to a polygon.
Using ArcMap's Raster to Polygon tool, I'm able to get something close to that.
However, you can see that there are many diagonal lines (roads) which create chains of polygons that share a corner.
This ups my polygon count significantly - these raster datasets are being processed at the state level. Is there an Arc or GeoTools tool to smooth out these lines and create fewer polygons? It's okay if the result loses some precision. In the end, I'm looking for something similar to what I get with the simplified polygon, just with adjacent polygons joined.
