This paper presents the partnering arrangement, approach, and results achieved to date in a government, industry, and university co/laborarion to apply remote sensing and geographic infonnation system (GJS) technologies to the analysis ofphy/lo:xera damage in Napa Valley vineyards. NASA Ames Research Center; Robert Mondavi Winery; University of California, Davis; California State University, Chico; and the California Cooperative Extension are working together to use NASA developed technology to help solve a current industry problem. Seventy percent of Napa Valley\u27s premiere vineyards are susceptible to destrucrionfrom phyllo:xera, and the pest has been found in seven other wine growing counries in the state. The multi-disciplinary team is developing techniques to use field, aircraft, and satellite-based remote sensing daJa to detect phylloxera infestaJions both before and after visual symptoms are apparent. A GJS is used ro understand rhe spatial and temporal distribwion of the infestations. In 1993 field data was collected to see if the spectral reflectance of vine leafs varied with levels of phyl/o:xera infestation. Results were positive, and an aircraft platform was used to collect canopy level spectral reflectance. University and industry team members are very encouraged to see remote sensing applied to their issues, and are becoming advocates/or increased use of the data
