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.
