USDA-ARS Pacific West Area Remote Sensing Workshop
headline bar


The PWA Remote Sensing Workshop was held on 29-30 April 2009 in Albany, California.  The workshop was designed to interest PWA scientists using, planning to use, or thinking about using remote sensing (RS).  The objectives of this workshop were


1) information sharing, including both applications and state of the science; and

2) planning for future remote sensing research in PWA. 

The objectives were addressed through a unique workshop format that included Q&A sessions, facilitated discussions, a poster session, invited speakers and breakout sessions.

Workshop Agenda


29 April Wednesday



Opportunities for interaction were offered as follows:

1-2pm  MODIS and ASTER Q&A- Facilitators French and Hook

2-3pm  Ground-based remote sensing Q&A- Facilitators Clarke, Marks, Seyfried and Holifield Collins

3-4pm  Facilitated discussion on 2 topics (held in parallel):

         Cropland research - Facilitators Johnson, Hunsaker and Walthall

         Wildland research - Facilitators Bubenheim, Carruthers and Moran


Poster Session:  The poster session focused on critical research related to remote sensing.

Breakout sessions:  Breakouts will be organized to develop a strategy for remote sensing research in PWA based on our critical research needs.   Breakout discussion questions:

••         How can we best facilitate remote sensing in each unit?

••         How can we maximize inter-unit research collaborations and technology transfer?

••         What are some ideas for proposals to NASA Applied Sciences Program and other funding sources?

••         What are new RS initiatives to send to ONP to have on hand in case opportunities for new funding arise?


Plenary session: Breakout summaries.  Assign writing tasks for workshop minutes and define action items.
