The AI pulled the exact boundary files for two local councils

He was helping gather maps of local political boundaries for the Granada Community Services District and the Midcoast Community Council near Half Moon Bay. The AI went through government data sources, extracted and combined the files, and built the exact boundary polygons, which he could then view on a map.

How it works

  1. Asks the AI for the exact boundary of the Granada Community Services District in El Granada
  2. Asks for the Midcoast Community Council boundary near Half Moon Bay
  3. The AI extracts and combines files from different government data sources
  4. Both polygons are displayed together in his GeoJSON map viewer

Why it’s worth knowing

Ask for almost any boundary and it goes off, pulls the government files apart and hands back the exact shape.
