What's the benefit of defining polygons as opposed to using shapefiles? San Francisco, for example, has a good shapefile of all the neighborhoods in SF: https://data.sfgov.org/widgets/qc6m-r4ih

Hi there, I'm one of the engineers who worked on AT-AT.

Shapefiles are useful when we export data, but because we want to give our cartographer the ability to continually edit neighborhood boundaries, we store these as polygons in PostGIS. Hope this addresses your concern. Feel free to ask for further clarification.
