With emphasis on recent significant developments in remote sensing,
the theme of Pecora 20 is “Observing a Changing Earth, Science for
Decisions…Monitoring, Assessment, and Projection.”
The Pecora Symposium series was established by the USGS and NASA in
the 1970s as a forum to: 1) foster the exchange of scientific
information and results derived from applications of Earth observing
data to a broad range of land-based resources; and 2) discuss ideas,
policies, and strategies concerning land remote sensing.
