The next stage of analysis allows for additional adjustment of
the burn threshold based on the ecosystem of interest. The
thresholds are adjusted manually based on the success rate of
burned area masks mapped with the previously determined burn
threshold. The MODIS Vegetation Continuous Fields (VCF)
product (Hansen et al., 2003) provides important information
about tree and herbaceous cover which is incorporated into
additional thresholds within the GIS processing steps. A sample
fire scar from the validation base is used to create a high
confidence mask of a burned area. The distribution of MODIS
post-fire dNBR values within the mask is then evaluated as a
function of percent tree cover and percent herbaceous cover
(Fig. 5). This evaluation yields vegetation cover thresholds
subsequently used to adjust the burn thresholds. Within the
sagebrush steppe test site, all areas with tree cover >2% and
areas with herbaceous cover >72% performed adequately.
However, areas with tree cover ≤2% and herbaceous cover
≤72% were not mapped well. Subsequently, the burn threshold
for the underrepresented areas was moved to the lowest level of
“potentially burned” pixels—a dNBR value of 75. Similarly, the
