The Brazilian savanna, locally known as "cerrado", is the most intensely stressed biome with both naturaland human-induced pressures. In this study, we aimed to improve discrimination and characterization of the Brazilian cerrado physiognomies using hyperspectral Hyperion imagery, the first space-borne imaging spectrometer onboard the NASA's Earth Observing-1 (EO-1) platform. A Hyperion image w...

Two Hyperion images of the Greenland ice sheet are used to characterize errors in the VNIR and SWIR detector arrays of Hyperion. Spatial variability in detector output is seen in both arrays and, in both cases, is largest at the shorter wavelengths and decreases as wavelength increases. Standard deviations of the maximum variability are 40 DN for the VNIR array and 123 DN for the SWIR array. Te...

We develop Hyperion a Wearable Augmented Reality (WAR) system based on Google Glass to access text information in the ambient environment. Hyperion is able to retrieve text content from users’ current view and deliver the content to them in different ways according to their context. We design four work modalities for different situations that mobile users encounter in their daily activities. In...

A plot of spin rate versus orientation when Hyperion is at the pericenter of its orbit (surface of section) reveals a large chaotic zone surrounding the synchronous spin-orbit state of Hyperion, if the satellite is assumed to be rotating about a principal axis which is normal to its orbit plane. This means that Hyperion's rotation in this zone exhibits large, essentially random variations on a ...

Moreton Bay is the Australian EO1-Hyperion coastal site used for Cal/Val activities. Moreton Bay shows spatial gradients in optical depth, bathymetry, and substrate composition. The turbid and humic river inputs, as well as the open ocean flushing, determine the water quality of the bay. Recently lyngbya toxic algae blooms have become a serious environmental and health concern. The field campai...
