Creator:: Wulder, Michael A., Hilker, Thomas, White, Joanne C., Coops, Nicholas C., Masek, Jeffrey G., Pflugmacher, Dirk, and Crevier, Yves
Abstract:: Free and open access to satellite imagery and value-added data products have revolutionized the role of remote sensing in Earth system science. Nonetheless, rapid changes in the global environment pose challenges to the science community that are increasingly difficult to address using data from single satellite sensors or platforms due...

Creator:: Pflugmacher, Dirk, Cohen, Warren B., Kennedy, Robert E., and Yang, Zhiqiang
Abstract:: Improved monitoring of forest biomass and biomass change is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, moderate spatial resolution, and long history of earth observations provide a unique opportunity for characterizing vegetation changes across large areas and long time scales....

Creator:: Kennedy, Robert E., Andréfouët, Serge, Cohen, Warren B., Gómez, Cristina, Griffiths, Patrick, Hais, Martin, Healey, Sean P., Helmer, Eileen H., Hostert, Patrick, Lyons, Mitchell B., Meigs, Garrett W., Pflugmacher, Dirk, Phinn, Stuart R., Powell, Scott L., Scarth, Peter, Sen, Susmita, Schroeder, Todd A., Schneider, Annemarie, Sonnenschein, Ruth, Vogelmann, James E., Wulder, Michael A., and Zhu, Zhe
Abstract:: When characterizing the processes that shape ecosystems, ecologists increasingly use the unique perspective offered by repeat observations of remotely sensed imagery. However, the concept of change embodied in much of the traditional remote-sensing literature was primarily limited to capturing large or extreme changes occurring in natural systems, omitting many more...

Abstract:: Lidar is currently the most accurate method for remote estimation of forest structure, but it has limited spatial and temporal coverage. Conversely, Landsat data are more widely available, but exhibit a weaker relationship with structure under medium to high leaf area conditions. One potentially valuable means of enhancing the relationship...

Creator:: Pflugmacher, Dirk, Krankina, Olga N., Cohen, Warren B., Friedl, Mark A., Sulla-Menashe, Damien, Kennedy, Robert E., Nelson, Peder, Loboda, Tatiana V., Kuemmerle, Tobias, Dyukarev, Egor, Elsakov, Vladimir, and Kharuk, Viacheslav I.
Abstract:: Information on land cover at global and continental scales is critical for addressing a range of ecological, socioeconomic and policy questions. Global land cover maps have evolved rapidly in the last decade, but efforts to evaluate map uncertainties have been limited, especially in remote areas like Northern Eurasia. Northern Eurasia...
