Trip Report
Attendee:
Jim Dewald
Representing: SDSU
Travel Dates: March
23 – 28, 2002
Location:
Reston, VA and Greenbelt, MD
This trip consisted of two primary components, the 1st
activity was a three day workshop held at USGS located in Reston, VA. The
meeting focus was to present a series of updates regarding High Spatial
Resolution Commercial Imagery. Both technical system related issues and
application of the data were discussed. Primary system’s discussed were as
follows: Ikonos, Quick Bird, and Landsat 7. Reference the agenda for details.
Papers presented will be sent to the attendee’s on a post meeting CD (not yet
received) and will be circulated at SDSU to interested parties. During the
workshop, the following individuals were consulted about activities related to
remote sensing summer field campaign work to be performed near SDSU: Dr. Bob
Ryan and Mary Pagnutti, representing Lockheed Martin at the Stennis Space Flight
Center, and Dr. Kurt Thome, representing the University of Arizona. The
discussions centered on organizing joint activities, including shared equipment
and personnel. A side bar discussion between myself and Dr. Thome focused on
initial results obtained from an analysis of Hyperion data that I am performing
that relies on atmospheric radiometric correction computations the Dr. Thome
provided. From my perspective, the insight gained from this discussion was
invaluable. One additional discussion of note was with Larry Biehl, representing
Purdue University. Dr. Biehl presented an application paper and poster on
utilizing Ikonos data to perform detailed studies of crop conditions, and during
informal visits provided some guidelines to myself and Dave Aaron about the
process that was undertaken and some of the inherent limitations. This
discussion while outside of the engineering technical arena, was informative and
will prove useful during the SDSU EPSCoR precision farming project.
The final day, was devoted to a visit to the GSFC in Greenbelt, MD. Several key NASA personnel were met, and a 3 hour meeting was held to jointly update everyone with respect to Landsat 5 & 7 sensor stability. Dr. Helder of SDSU briefed the group regarding research work to characterize the long term changes that have been detected. The findings, so far, are interesting but also inconclusive and will require further investigation. Thus forming potential long term project, and funding, opportunities.
