abstract = "In times of global environmental change, the sustainability of
human-environment systems is only possible through a better
understanding of ecosystem processes. An assessment of
anthropogenic environmental impacts depends upon monitoring
natural ecosystems. These systems are intrinsically complex and
dynamic, and are characterized by ecological gradients. Remote
sensing data repeatedly collected in a systematic manner are
suitable for describing such gradual changes over time and
landscape gradients, e.g., through information on the vegetation's
phenology. Specifically, imaging spectroscopy is capable of
describing ecosystem processes, such as primary productivity or
leaf water content of vegetation. Future spaceborne imaging
spectroscopy missions like the Environmental Mapping and Analysis
Program (EnMAP) will repeatedly acquire highquality data of the
Earth's surface, and will thus be extremely useful for describing
natural ecosystems and the services they provide. In this
conceptual paper, we present some of the preparatory research of
the EnMAP Scientific Advisory Group (EnSAG) on natural ecosystems
and ecosystem transitions. Through two case studies we illustrate
the usage of spectral indices derived from multi-date imaging
spectroscopy data at EnMAP scale, for mapping vegetation
gradients. We thus demonstrate the benefit of future EnMAP data
for monitoring ecological gradients and natural ecosystems.",
