With the launch of NASA's Terra satellite and the MODerate Resolution Imaging Spectroradiometer (MODIS), operational Bidirectional Reflectance Distribution Function (BRDF) and albedo products are now being made available to the scientific community. The MODIS BRDF/Albedo algorithm makes use of a semiempirical kernel-driven bidirectional reflectance model(More)
— The European Space Agency's Project for On-Board Autonomy is intended to demonstrate a range of innovations in the design, construction and operation of small satellites. It carries a number of scientific instruments, the most advanced of which is the Compact High-Resolution Imaging Spectrometer. A typical nadir image is 13km × 13km in size and has 18(More)
The Compact High Resolution Imaging Spectrometer (CHRIS), to be launched on board the PROBA (Project for On-Board Autonomy) satellite in 2001/2002, will provide remotely-sensed data for terrestrial and atmospheric applications. The mission is intended to demonstrate the potential of a compact, low-cost, imaging spectrometer when combined with a small, agile(More)
Per-pixel classification algorithms are poorly equipped to monitor urban land use i n images acquired by the current generation of high spatial resolution satellite sensors. This is because urban areas commonly comprise a complex spatial assemblage of spectrally distinct land-cover types. In this study, a technique is described that attempts to derive(More)
Land surface albedo is dependent on atmospheric state and hence is difficult to validate. Over the UK persistent cloud cover and land cover heterogeneity at moderate (km-scale) spatial resolution can also complicate comparison of field-measured albedo with that derived from instruments such as the Moderate Resolution Imaging Spectrometer (MODIS).

Previous studies have shown that for some populations of marine turtle, individuals move along narrow migration corridors in the open ocean. It has been suggested that these migration corridors may correspond with near-surface oceanographic features that can be detected by remote sensing. This idea is examined by superimposing the tracks of green turtles(More)
