Terrestrial Imaging Spectroscopy – Some Future Perspectives
نویسنده
چکیده
This paper covers 60 years of terrestrial imaging spectroscopy or hyperspectral remote sensing – 30 years each devoted to past and future developments. For this purpose, a brief history of imaging spectroscopy is given, covering civilian airborne sensor and spaceborne mission developments and associated data processing capabilities. Moreover, the paper reviews the existing and planned space systems, examines the current status in hyperspectral remote sensing in terms of data quality and availability, algorithm development, data processing, and applications development. Although many problems have been overcome since the advent of hyperspectral remote sensing, there are still major bottlenecks, as pointed out in this paper, which need to be addressed to further advance this area. Future needs in hyperspectral remote sensing are summarized in terms of space missions and the data products they provide, algorithm development, data processing, and applications development. The paper will conclude by speculating on civilian hyperspectral systems that might be in operation for terrestrial imaging 30 years down the road. In addition, an outlook of the data processing capabilities needed to analyse the increasing volume of data is given for the same time frame.

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 collecte...
متن کاملImaging spectroscopy- and lidar-derived estimates of canopy composition and structure to improve predictions of forest carbon fluxes and ecosystem dynamics
The composition and structure of vegetation are key attributes of ecosystems, affecting their current and future carbon, water, and energy fluxes. Information on these attributes has traditionally come from ground-based inventories of the plant canopy within small sample plots. Here we show how imaging spectrometry and waveform lidar can be used to provide spatially comprehensive estimates of f...
