A focused geo-agent app for California environmental-justice analysis, centered on CalEnviroScreen 5.0 (Draft, January 2026).
Live app: https://calenviroscreen.nrp-nautilus.io
The app combines a MapLibre map with an LLM chat assistant. The assistant can query the underlying GeoParquet datasets via a DuckDB MCP server, so users can ask questions in plain English about pollution burden, demographics, district-level CES summaries, and the overlap between burdened communities and conservation investments.
Built on the boettiger-lab/geo-agent
framework. Configuration lives in three files: layers-input.json,
system-prompt.md, and index.html.
