nrt_burn_severity

Workflow for generating burn severity maps in google earth engine from user-provided fire perimeters

Steps to Map Burn Severity:

1. Download Fire Perimeter vector data from a reliable source.
   • On Our latest use of this repository, we used pull_nifc_fires.py, but we also have CLI scripts for CalFIRE and MTBS fire perimeters.
2. Upload those Fire Perimeters to GEE as a FeatureCollection.
3. Use the BS_Mapper.ipynb to produce categorical burn severity ee.Image's, plugging the Fire Perimeter ee.FeatureCollection(s) in as the inputs. Then export either to GEE Asset or Google Drive.

NOTE: For use in FireFactor product cycle, export yearly CONUS-wide BS to ee.Images under this GEE Asset folder: projects/pyregence-ee/assets/workflow_assets/ and use the base name prefix - BS_[perimetersSource]_[YEAR]. Those ee.Image's will be consumed by this CLI script for FireFactor: https://github.com/pyregence/landfire/blob/main/src/CreateDistLayer/create_dist_wildfire.py.
