What does this data set describe?

Title: Fourmile Canyon Fire Perimeter
Abstract:
Fourmile Canyon Fire Perimeter from the 9/12/10 Infrared flight conducted by US Forest Service. A US Forest Service Infrared Interpreter analyzes the flight data and produces a map showing the heat sources, draws an accurate fire perimeter, and calculates the acreage of the fire.
Supplemental_Information:
Aircraft/Scanner system: N149Z/Phoenix. It has the capability to downlink the digital imagery wirelessly via Aircell while airborne. Then an Infrared Interpreter retrieves the files from a server, analyzes the data, produces a map showing the heat sources, draws an accurate fire perimeter, and calculates the acreage of the fire.
Flight Date: 9/12/10 Flight time: 0118 MDT Comments on Imagery: Three runs. Georectification okay, imagery clear. Date and Time Imagery Received by Interpreter: 9/12/2010 0200 MDT Date and Time Imagery Delivered to Incident: 9/12/2010 0500 MDT
Notes/Comments on the mission and interpretation: "No change in the heat perimeter tonight. Much less heat detected on this mission than on previous missions. Only isolated heat sources were detected by the IR scanner tonight. They were all well interior to the perimeter. On the east side of the incident, there were a few areas that had weak heat signatures, but nothing hot enough to trigger the fire detection algorithm. There were two main areas where the isolated heat was detected. The first area was on the south side of the Gold Run drainage, with a few heat sources on the north-facing slope coming off the top of Monument Hill down into Gold Run - in the NE quarter of section 13, and several heat sources in the NW quarter of section 18 - some just to the north of the top of Melvina Hill in a steep NE facing drain running down into Gold Run, and the others further to the NW just sourth of the road and Gold Run. The other area of isolated heat sources is on the north-facing slope of the Fourmile Creek drainage in sections 24 and 25. Three are in about the center of section 24, approximately mid-slope. There were two other heat sources higher up on the slope about 1/3 to 1/2 mile south of Wallstreet, in the SE quarter of section 19, with one located near the section line. The final heat source mapped tonight was in the residential area near the top of Logan Hill. It appeared to be right next to the road, possibly in some trees. On the east side of the incident, there were a few areas that had weak heat signatures, but nothing was hot enough to trigger the fire detection algorithm. No heat perimeter was mapped tonight, and the incident fire perimeter was used on the maps."
