Data Sources

Near-real-time forest-clearing alert points from satellite radar and optical sensors, 10–30 m resolution.

Annual tree cover loss (>30% canopy density) at 30 m resolution. On the map it's a pixel raster streamed live from GFW's tiles, coloured by density (amber → deep red) with a 2001–2025 timeline; also aggregated by region for the region-page chart. Tree cover loss is not always deforestation.

Concession boundaries for oil palm (1,855), pulpwood (295), and logging (259) in Indonesia.

688 WDPA protected areas and 42,027 KLHK forest moratorium (PIPPIB) polygons.

Indonesia's mangrove extent from satellite imagery (2020), a critical coastal habitat for proboscis monkeys, crocodiles, water birds, and fish nurseries.

Indonesia's peatland extent, a carbon-rich, fire-prone ecosystem and important habitat that vanishes when drained and burned.

Satellite-mapped mined land, the physical footprint of mining for ALL minerals, Aceh to Papua, peer-reviewed. This is our primary mining dataset (not permit boundaries).

Density areas of conservation-priority species (IUCN-threatened + flagship/endemic), all classes, derived from GBIF occurrence points (1990–present), NOT official range polygons. Density is weighted by natural-habitat cover (ESA WorldCover: forest, savanna, wetland, mangrove) with city points dropped, then contoured per island so each species stays on its island (a Sumatran tiger never bleeds into Java). Spans every region: Sundaland, Wallacea (anoa, maleo, Komodo), Papua (tree-kangaroo, echidna), and the sea & rivers. For cryptic species whose coordinates are withheld for protection (e.g. rhino), documented-range markers (IUCN/KLHK) are added, clearly flagged and not field records. IUCN's official range polygons are not used because their licence restricts redistribution.

Event-level flood/landslide records from the UNDRR mirror of DIBI. Location is the kabupaten centroid (an approximation), not the exact point.

True-colour satellite mosaic for ONE chosen day, streamed straight from NASA GIBS tiles (keyless, not processed by us). Used to check land & forest fires: smoke and burn scars are visible to the naked eye, so a hotspot can be matched against what the sensor actually recorded. The product name shown on the map is the exact Worldview layer name, so the same day can be opened and compared in Worldview.

FIRMS thermal-anomaly detections for one chosen day, so a fire season can be replayed day by day — unlike the Hotspots (48h) layer, which is near-real-time only. Because GIBS publishes these vector tiles in EPSG:4326 only, this layer is drawn via the GIBS WMS as an image, and is therefore not clickable. A hotspot is an unverified heat detection, not proof of a fire nor of any party's involvement.

OpenStreetMap-derived place names, boundaries, roads, and coastlines served by NASA GIBS. Shown automatically with the NASA satellite imagery (not a separate layer): that imagery covers the basemap and its labels, so this overlay restores locational context. Orientation only — not an environmental data source, and not used in any calculation.

Province and district boundaries underpinning the map and aggregations.

Names and stages are rewritten from primary sources. Map points are district centroids until official polygons are open. Tanahkita is a discovery index only.

Every record has a source link. Company names come from the sources, not as accusations by this site.

Star-schema warehouse for agrarian conflict and community-managed land. The Riau dashboard uses province code 14: 25 conflicts (8 Indigenous), 94 managed territories, 17 AKKM. Not an authoritative source; credit Tanahkita.
