The NASA Affiliated Research Center (ARC) program recently approved STS's request to assist with developing post-pricessing geo-referencemethodology for airborne hyperspectral remote sensing techniques. In 1997 and 1999, STS collected airbornehyperspectral remote sensing data to assist a client in the evaluation of crop stress and damage introduced by land application of wastewater sludge. In 1997, the first generation sensor technology was not geo-referenced. Later, in 1999, several technical advancements included global postioning system (GPS) instantaneaous geo-reference capabilities and navigation correction by an integrated navigation system (INS) for pitch, roll and yaw of the aircraft sensor. The research will be conducted at the University of Wisconsin-Madison, Environmental Remote Sensing Center (ERSC). ERSC staff will evaluate various techniques to post-process the 1997 data so that a change comparision with the subsequent crop years including 1999 may be evaluated by co-registering the different image maps. The co-registered remote sensing data, along with the field research plots, can verify whether any of the originally observed crop stress may carry forward into subsequent crop rotations. NASA ARC program research is conducted at nine universities throughout the United States and is funded by the Commercial Remote Sensing Program (CRSP) based at the John Stennis Space Center in Mississippi. The ARC program is a successful collaboration between private sector firms, faculty researchers, and graduate students. The program strives to complete 36 national projects annually that demonstrate how to use spatial-information technologies to solve practical problems. |
