Earth observation imagery collected by the series of Landsat satellites constitutes the longest and most consistent collection of moderate spatial resolution remotely sensed data. Feedback from the Landsat user community has played an important role in assessing its utility and making improvements to future Landsat missions. The United States Geological Survey (usgs) and the National Aeronautical and Space Administration (nasa) continue to solicit input from user communities. This paper describes the outcome of soliciting input from experts associated with AmericaView (av), a non-profit organization aimed at promoting remote sensing applications in the us. The av community identified the importance of rigorously calibrated Landsat data for ...
