It’s great! Agreed don’t feed the trolls.

I’ve helped with a few other zoning visualization projects recently, similar workflow. The only similarity is that each city/jurisdiction makes its data available in a different way. It’s usually accessible but it does mean there’s a lot of work munging the data to a usable format.

Here’s one of the projects: https://github.com/kfarr/zoningviz

Yes, this is incredibly similar to the pipeline I ended up with -- https://github.com/kfarr/zoningviz/blob/main/HOW_IT_WORKS.md

The other thing I learned is that some of the data sets use a destructive insert, so unless someone is doing a data snapshot data elements can be lost. (The vendors charge extra time-series option.)
