Description: For several years, the USDA Forest Service has been making advances to the airborne thermal infrared imaging capabilities for wildland fire detection and mapping. The new Phoenix system represents the first time that a high productivity, digital, geo-corrected product is available for tactical fire intelligence and mapping. In conjunction with government and private sector developers and suppliers, a complete system has been developed tailored to the unique requirements of the wildland fire fighting community. Beginning with the 2003 fire season, two Phoenix systems were deployed in the United States for wildland fire detection and mapping missions. Included is an explanation of the imagery itself, the advanced GPS/inertial measurement unit and the resulting geo-corrected products, an operational orientation concerning the use of Phoenix and integrating Phoenix products into the incident command structure, and proposed future enhancements. Clean, clear imagery. Western scan box could probably be reduced on the east and western extents. Doing so would facilitate more overlap between the three strips on the west scan box. Tonight’s mapping began with the incident provided fire polygon dated 20161202 @ 2138 hrs which was located on the NIFC FTP. This perimeter included reduction in acres in some portions of the fire. In the main fire polygon, very few perimeter edits were made, limited to a small change in the southeast portion of the fire. Many isolated heat sources were mapped throughout the main fire polygon with the largest concentrations in the southern portion of the fire south of Highway 441. Fewer isolated heat sources were mapped in and around the community of Gatlinburg, though numerous heat sources do persist there. Weak heat signatures were mapped as “potential heat sources” though efforts were made to reduce the number of hot foundations mapped as heat in the absence of significant heat. Potential heat sources were also mapped in a number of the smaller fire polygons near Williamsburg and Little Cove Gap. The most active fire, and perimeter growth was found on the Cobbly Nob fire tonight. Perimeter growth was mapped, along with small polygons of intense heat along the northern portion of the fire’s eastern flank both north and south of Matthew Creek. A small polygon of intense heat was also detected along with some perimeter growth on a south face on the west side of Webb Mountain. Acre reduction due to enhanced fire perimeter received from incident. Reduction is from fire polygons in the west scan box, while the Cobbly Nob fire in the east scan box actually increased in size.
