Hyperspectral remote sensing (HRS), or imaging spectroscopy (IS), is a technology that can provide detailed spectral information from every pixel in an image. Whereas HRS refers mostly to remote-sensing means (usually from far distances), the emerging IS technology covers all spatial-spectral domains, from microscopic to telescopic. In general, being a technology that provides spatial and spectral information simultaneously, HRS-IS improves our understanding of the remote environment. It enables accurate identification of both targets and phenomena as the spectral information is presented on a spatial rather than point (pixel) basis. Furthermore, it provides a new capability—to quantitatively assess chemical and physical aspects of the pixel(s) in question. The IS-HRS technology is well accepted in the remote-sensing arena as an innovative tool for many applications, such as in geology, ecology, soil, limnology, pedology, plant biology and atmospheric sciences, especially for cases in which other remote-sensing means have failed or are incapable of obtaining additional information. Whereas innovative approaches have been developed over the past 10 years, mostly by scientists, the power of the IS-HRS technology is still unknown to many potential end-users, such as decision-makers, farmers, environmental watchers in both the private and governmental sectors, city planners, stock holders and others. This is mainly because the use of HRS-IS sensors still relies on the relatively high cost of its final products and on the need for professional manpower to operate the instrument and process the data. Nonetheless, today, in addition to the growing number of scientific papers and conferences focusing on this technology, the HRS-IS discipline is very active: commercial sensors are being built and sold, orbital sensors are in advanced planning phases, people are becoming more educated on the topic, national and international funds are being directed toward studying and using this technology from all domains (ground air and space) and interest from the private sector is on the rise. The aim of this special issue is to gather innovative papers dealing with this technology from all aspects giving special emphasis to remote sensing of the Earth.
