Remote Sensing of Ecosystem Structure and Function ����������������������������������������������

ByAlfredo R. Huete, Edward P. Glenn

Earth-observing remote sensing technologies are becoming widely adopted within the resource management, ecosystem sciences, and sustainable development communities. Satellite data offer unprecedented capabilities to capture the spatial and temporal detail of ecosystem properties at regional to global scales, and remote sensing tools are now employed in characterizing ecosystem structure and biologic properties and in monitoring ecosystem health, seasonal dynamics, and functional processes. The moderate resolution Landsat and coarser resolution National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) programs have provided systematic time-series observations since the early and late 1970s, respectively, for ecosystem and agricultural productivity assessments, land-cover mapping, vegetation-climate studies, drought monitoring, biodiversity and habitat loss, invasive species, and many other ecological applications.
