About the Webinar

To advance collective progress on remote sensing of surface composition, the IEEE GRSS GSIS TC is starting a working group to improve algorithms that characterize geology and geochemistry, that detail associated physical and chemical processes, and that link geology to biological function. A focus will be on expanding the number of well-validated case study areas to evaluate and compare existing and new sensors and algorithms. The group further seeks to highlight applications that promote the health of communities and the environment.  In order to open discussion among interested GSIS members and seminar attendees, this presentation will review some recent advancements in remote sensing including satellite sensors, airborne campaigns, and show results from preliminary comparisons of AVIRIS, EMIT, EnMAP, HISUI, and PRISMA at Cuprite, NV.

About the Speaker

Raymond Kokaly is an expert on the application of remote sensing and spectroscopy for vegetation and mineral characterization. His peer-reviewed publications on the use of spectroscopy include: quantifying biochemical content in leaf spectra, discriminating conifer species, examining post-fire surface cover, and characterizing the impact of oil contamination from the Deepwater Horizon spill. His research has used multispectral and hyperspectral remote sensing data from AVHRR, Landsat, Hyperion, AVIRIS, HyMap, and MODIS. Raymond created the PRISM software, a framework for archiving and analyzing spectroscopic data collected in the laboratory and the field and from remote sensing platforms. PRISM was applied to map surficial minerals across most of Afghanistan, covering more than 480,000 sq. km. an area about the size of the state of California.
