This work examines the application of a geometric-optical canopy reflectance model to provide measures of woody shrub abundance in desert grasslands at the landscape scale. The approach is through inversion of the non-linear simple geometric model (SGM) against 631 nm multi-angle reflectance data from the Compact High Resolution Imaging Spectrometer (CHRIS)(More)
This paper reports a new technique that combines the features of Accumulative Roll Bonding (ARB) and Asymmetric Rolling (AR). This technique has been developed to enable production of ultra-thin bimetallic foils. Initially, 1.5 mm thick AA1050 and AA6061 foils were roll-bonded using ARB at 200°C, with 50% reduction. The resulting 1.5 mm bimetallic foil was(More)
A new method is described for the retrieval of fractional cover of large woody plants (shrubs) at the landscape scale using moderate resolution multiangle remote sensing data from the Multiangle Imaging SpectroRadiometer (MISR) and an hybrid geometric-optical (GO) canopy reflectance model. The major difficulty in applying such models in desert grasslands is(More)

The paper studied the characteristics of arid and semi-arid lands carefully and an inversion method of a non-linear simple geometric model (SGM) with multi-angle CHRIS data was investigated and the results were reasonable. Some questions are listed below in detail. (1) Is the resolution between (a) and (b) the same? Response: We assume the reviewer is(More)
Project Status: Ongoing, funded: a portion of US$30k/yr through the JORNEX campaign. The first CHRIS image set over the Jornada Experimental Range (JER) was acquired on 5 th August, 2002 but until November only the browse image was available. In May 2003 we requested monthly acquisitions as overlapping images became available. Activities and(More)
Shoreline information is fundamental for understanding coastal dynamics and for implementing environmental policy. The analysis of shoreline variability usually uses a group of shoreline indicators visibly discernible in coastal imagery, such as the seaward vegetation line, wet beach/dry beach line, and instantaneous water line. These indicators partition a(More)
