JRC Tropical Moist Forests

Developed by the European Commissions Joint Research Centre (JRC), this dataset maps forest cover change in tropical moist forests (TMF) using 43 years of Landsat time series. At 30m resolution, it depicts TMF extent, disturbances (deforestation and degradation), and post-deforestation recovery (regrowth). The provided dataset only includes some of the layers; see limitations for more details.

Useful for

Use cases llm-inferred
Deforestation and degradation history for overseas project sites (supply-chain or ESG due diligence) · Pre-development forest cover change baseline for international environmental impact assessments · Land-cover change context for overseas biodiversity or carbon offset screening

Limitations

Constraints docs-verified
Pan-tropical only; no UK coverage · Mirrors six download products only; Intensity and Duration (Earth Engine only) are not mirrored · 10 m Hybrid Transition Map not mirrored (beta, 1990 to 2022) · Tile IDs are nominal; do not compute pixel offsets from the ID, read exact bounds from the raster or STAC footprint · Icechunk cube has one group per tile, not one global array; tile pixel counts vary and are not multiples of 512 · Attribution required; re-packaging must be stated; mirror does not imply EC endorsement
