What to build

Compile official KLHK annual fire perimeters and MODIS/Sentinel-2 burn scar products covering the historic catastrophic El Niño fire seasons (2015, 2019, and 2023) into burn_scars_historical.pmtiles.

Technical specifications

1. Target files:
   • scripts/build-burn-scars-pmtiles.sh: Tippecanoe compilation script.
2. Parameters:
   • Zoom range: z4 to z12.
   • Layers: burn_scars_2015, burn_scars_2019, burn_scars_2023.
   • Output: public/tiles/burn_scars_historical.pmtiles.

Acceptance criteria

• Produces verified burn_scars_historical.pmtiles archive under 40 MB.
• Each feature contains normalized tahun (year) and luas_ha attributes.

Blocked by

• Issue 20: [Backend] Geometry validation & GEOS topology repair (rustgis clean).
