The National Burned Area Composite (NBAC) is a national, geospatial burned area product compiled annually since 2004 for annual estimates of carbon emissions. A rule-based decision process is used to select the best burned area represention from a number of available data sources.
The NBAC is created as a component of the Fire Monitoring, Accounting and Reporting System (FireMARS), jointly developed by the Canada Centre for Mapping and Earth Observation (formerly the Canada Centre for Remote Sensing) of Natural Resources Canada and the Canadian Forest Service. FireMARS was initially developed with funding support from the Canadian Space Agency Government Related Initiatives Program through a collaboration of those in fire research, forest carbon accounting and remote sensing. The NBAC can be used for spatial and temporal analyses of landscape-scale fire impacts.

NBAC is a national product compiled annually since 2004 by the FireMARS system which tracks
forest fires for annual estimates of carbon emissions and to help identify National Forest
Inventory plots that may have been disturbed by fire.See the FireMARS website at
http://www.nrcan.gc.ca/forests/fire/13159 and carbon accounting - disturbance monitoring
website (http://www.nrcan.gc.ca/forests/climate-change/13109) for additional information.
Data from two types of providers is used to generate NBAC:
1) Natural Resources Canada, and
2) Provincial, Territorial, and Parks Canada agencies.
A rule-based decision process is used to select the best data source for each fire event based
on factors such as how well the burn polygon follows the shape of the fire as observed on postburn
satellite imagery, the data source itself, and what methods were used to delineate the
burn. Not all fires are mapped and in areas where there was not a lot of fire activity to warrant
satellite image mapping, agency data is used.
