Interactive map

A live MapLibre canvas with FUNAI Indigenous Lands and INPE DETER alerts overlaid on OpenStreetMap.

How to use it

1. Open /app/ — the map starts centered over the Brazilian Amazon.
2. Toggle FUNAI and DETER layers from the side panel.
3. Pan or zoom — DETER alerts re-fetch automatically for the new view.
4. Click any point to open the inspector. It fetches the observed GPCP precipitation record, a CMIP6 climate trajectory, and recent Sentinel-2 imagery for that location in parallel.

API endpoints

Data sources

• Sentinel-2 L2A

Limits & caveats

• All overlays are read-through — no caching yet (Phase 2).
• FUNAI's WMS occasionally throttles; OSM basemap remains usable when it does.
• Alert refresh is debounced to the visible extent only.
