Natural Resource Area Report
APAN Conference 2002
23rd-24th January 2002
The GOFC Fire Mapping and Monitoring Implementation Team has embarked on an effort to improve the understanding and use of satellite observations of fires through a series of regional calibration / validation activities. Satellite observations of active fires and burn scars may provide
data useful in the monitoring and forecasting of disasters from fires,especially during the dry season caused by climate variability. However,little is known about the validity and accuracy of the various products and how they might be used together for an improved depiction of fire events.
The core activity of the workshop was to initiate and plan the intercomparison, calibration, and validation of active fire and burn scar products from primary systems capable of making wide area coverage observations in S.E. Asia. The workshop included presentations on the
SEARIN network, a definition of objectives, a review of remote sensing accuracy assessment, and multiple presentations from regional scientists regarding their experiences in validating fire and burn scar observations.
The plans focus on the collection and analysis of multiple sources of satellite imagery and filed data in tests sites selected in Thailand, Indonesia and Malaysia. The systems to be considered include the near real time images from MODIS, AVHRR, and DMSP. Reference data sources include high spatial resolution data from Landsat, SPOT, ASTER,
which will provide active fire detection and burn scar maps for use in performing an accuracy assessment of the coarse resolution sources.
