Release
V1 platform launch — all four catalogs live
Initial public release of FuelMaps. Fuel Hazard (6 metrics), Fuel Load (GEDI L4A biomass), Fuel Type (NBIC ACS Stage 2 BFC) and Forest Metrics (6 layers) all available for 2017–2025 at 10m resolution.
All catalogs2017–202510m
Assumptions
Project-level assumptions and caveats
5 entries
GEDI footprint sampling is unbiased at 10m aggregation
Data
GEDI L4A footprints (~25m diameter) are assumed representative when aggregated to 10m. Slope >40° and canopy cover >95% cause under-sampling in tall dense forests.

Models developed for Victorian ecosystems
Scope
Current datasets cover Victoria and trained on Victorian ecosystems. Expansion to other regions may require training region specific models.
Affects: All catalogsPriority: Low
Known Issues
Active bugs, artifacts and limitations under investigation

Medium
Review the masking rules behind this for areas in Wilsons Prom and along the Gippsland coastline.
