ARCHER Ground Staton in MoNG
The critical event for the Project was collecting the HSI. CAP completed ARCHER test and evaluation in spring 2005, and took delivery of the first operational aircraft that summer. Because of the impending end of the Pilot Project in September and the need for post-collection time to complete the analysis, CAP was asked to conduct an ARCHER mission in August. An operational aircraft and crew were not available. However, Col. Alexa, CAP ARCHER Project Officer, and Mr. Pete Kalisky, CAP Headquarters National Operations Center (NOC) brought together a crew that had participated in testing and the ARCHER prototype aircraft, and deployed to Jefferson City, August 7 through 9. The Missouri Army National Guard (MoNG) provided a training room in their hanger at the Jefferson City airport for CAP, University of Missouri Columbia (UMC) and department personnel to plan and execute two days of collection missions. The ARCHER aircraft was housed in the Missouri Office of Administration (OA) hanger.
UMC IMAGINE Hyperspectral Imagery Workstation
The aircrew arrived in Jefferson City, Sunday, August 7. They were briefed on the Project's objectives, and provided charts of the target areas and graphics of the sites for Monday. The ARCHER sensor operators then entered the flight data and site coordinates in their handheld ARCHER Trac computer in preparation for the morning mission. On Monday, August 8, the aircraft was taxied from the OA hanger to the MoNG hanger, where the ARCHER ground station was off-loaded and set up in the training room. When ARCHER deploys from its home base, all airborne and ground equipment is carried in the aircraft. Extra crewmembers join the aircraft at the deployment site.
The UMC RemoteSensing personnel also set their IMAGINE HSI workstation up in the training room. The HSI data was downloaded from the aircraft to the ARCHER ground station, where Dr. Kershenstine, CAP, ARCHER Project Office, reviewed it for quality and completeness. The data was then be transferred to the IMAGINE workstation to ensure it could be processed and analyzed. The UMC personnel conducted limited review of the imagery on site. All of the analyses for the Project was done using IMAGINE at UMC. A description of the procedures for processing the HSI data by UMC, and the review and analysis with site PMs is described in the final report.
ARCHER Flight Planning
Seven sites were covered on the August 8, morning mission: JZ Landfills, Weldon Spring Site Remedial Action Project, Tyson Valley Powder Farm, Praxair Inc. Industrial Gas Plant Fire, Industrial Flood Sites in St. Louis, Herculaneum Lead Smelter, and Hematite Radiological Site. Transit time from Jefferson City to the St. Louis area was about 45 minutes, making the first mission approximately four hours. It became apparent that cramped conditions in the aircraft and the day's warm temperatures would limit collection for the afternoon flight.
Due to transit times and lighting conditions, the Monday afternoon mission was reduced to a single pass of a portion of the Big River contaminated with lead mine tailings, and area coverage of Mineral Point and Potosi where lead contamination from mining operations has been detected in high levels in residential areas. The aircraft normally flies at 2500 ft, resulting in imagery with a one-meter resolution. A low-level pass was conducted in Potosi to evaluate the application of higher resolution imagery to detection of lower concentrations of contamination.
One mission was flown Tuesday morning to southwest Missouri. The primary sites were three residential areas affected by lead mining. Southwest Missouri, the Tri-State Mining District, is one of three Missouri metal mining locations, each with a different mixture of lead and other metals. The Tri-State area, which includes southeast Kansas and northern Oklahoma, has extensive tailings piles with high concentrations of zinc. Three locations were imaged, Wentworth, Aurora and Grandby. Each location covered an approximately 2 km x 2 km area.
