Bounding Polygon for Complex Feature Set

BertGranbergWFRC — Fri, 05 Feb 2021 16:39:48 GMT

We are looking to dissolve adjacent and nearby parcel geometry that we have identified and attributed as participating in a common subdivision, and merge these into a single, bounding, space filling polygon that closely approximates the outer boundary of the area. (mocked up in the attached images).

The existing geoprocessing envelope tools that we are aware are only able to produce envelopes or convex hulls. As we have thousands of these, we are hoping to avoid manual editing touches where possible. But even tool or process that isn't perfect it would be nice to give even if minor cleanup is still needed.

Hey Bert- what have you used and what is the desired result? Do you want to have the right of ways dissolved out as well so you have a 'solid' subdivision polygon? (SLCo has such a feature layer...)

It looks like Pro's Aggregate Polygons tool should work for what we want to
do. Good to know about the county's subdivision dataset. That would work if
the PUDs are broken up according to different housing type areas
(townhouses, single family, condos etc).

It's not that detailed, just a subdivision name is all.
