2.1 Forest Fire Risk Prediction • Purpose • National/Regional-level prediction on forest fire risk • To get the forest fuel types of China. • To get the method to estimate the Relative Greenness. • To get the method to estimate the Fuel Moisture Content. • To get the methodology of forest fire danger rating System.
2.1 Forest Fire Risk Prediction Forest Distribution Administrative Boundary Remote Sensing Data Forecast Data Observation Data on Fire Danger Meteorological Observation Data …… GIS Satellite-Data Network Public Network FT RG FMS Prediction Models Results FT: Fuel Type RG: Relative Greenness The flowchart of Forest Fire Risk Prediction FMC: Fuel Moisture Content
Fuel Types 250m Spatialresolution: 1km
Fuel Greenness Estimation Relative Greens, Spatial Resolution 1Km (2001,9.23~9.30)
Water absorb • Forest Fuel Moisture Content Reflectivity – Waver Length Spatial Resolution : 1KM (2001,9. 23~9.30)
2.2 Forest Fires Monitoring • Purpose • Todetect burning in the vast forest areas • Tomapping large fires for fire suppression • To monitor all phases of a fire in the key regions • To get the fire distribution pattern using satellite data
2.2 Forest Fires Monitoring • Satellite Data • NOAA-AVHRR Data (1.1km) • MODIS Data (1.0km) • ENVISAT-AATSR Data (1.1km) • TM/ETM+ (30m) • SPOT 5 (10m) • FY 3A/B (1.0 km) • HJ-1B (150M)

Fireline Extraction Results: mapping large fires for fire suppression April 29, 2009, ETM, Spatial Resolution:30meter
Fire Distribution Pattern • To get the spatial and temporal distribution pattern
Fire Distribution Pattern Annual total fire point by province, MODIS Data
Fire Distribution Pattern Monthly total active fire counts belong to broadleaf forests for years 2000 - 2011
2.3 Burned Area Mapping • Purpose • To map burnt area borderline using satellite image • To evaluate the damage by forest fires
2.3 Burned Area Mapping Satellite Data Image processing Boundary Extracting Burned Information Enhance GIS Databases (Forest Map, DEM, etc.) Burned Area Maching, Overlay Analysis Burned Forest Type Burned 3D Visualize Damage The flowchart of Burned Area Mapping
