Make Non-Overlapping Buffer Rings that only is affected by Source Point

ElysiaFuller-Thomson — Wed, 07 Sep 2022 19:20:32 GMT

I am trying to create a 400 m to 800 m outer ring around many points that exist in the same shapefile.

When I try the multiple ring buffer tool with non-overlapping or the buffer tool followed by an erase, the other adjacent points interfere with the ring cutting off some of the area I would like.

What I would like to see is perfectly intact rings, even if two points are withing 400 m of each other, so that all the rings would like this:

Any ideas?

There's probably a way to do it with tools, but you can easily do this with a Python script:

in_features = "TestPoints" inner = 400 outer = 800 out_dir = "memory" out_name = "ring_buffer" # create the output fc sr = arcpy.Describe(in_features).spatialReference out_feature = arcpy.management.MakeFeatureclass(out_dir, out_name, "POLYGON", spatial_reference=sr) arcpy.management.AddField(out_feature, "Orig_FID", "LONG") with arcpy.da.InsertCursor(out_feature, ["SHAPE@", "Orig_FID"]) as i_cursor: with arcpy.da.SearchCursor(in_features, ["SHAPE@", "OID@"]) as s_cursor: for shp, oid in s_cursor: # create inner and outer buffers b_inner = shp.buffer(inner) b_outer = shp.buffer(outer) # get the geometric difference -> the ring ring_shp = b_outer.difference(b_inner) # write the ring into the output fc i_cursor.insertRow([ring_shp, oid])
