Partial least squares regression (PLSR) is a powerful tool that makes use of the information at all wavelengths and provides the means for the quantitative determination of a wide variety of plant canopy properties. Past studies that limited their analysis to the use of spectral indices (e.g. NDVI, SAVI, PVI - see links below for more details) often weren't able to take advantage of the full spectrum since multispectral systems provide information at a limited set of wavelengths.
Two weeks from now, the SPIE 2012 Defense, Security and Sensing conference will convene - the largest unclassified event of its kind showcasing the latest in technology, thought leadership and technical presentations.
ASD’s own CTO and co-founder, Dr. Brian Curtiss, will present as one of the notable speakers at the conference. Additionally, ASD will demonstrate the latest in remote sensing technology at our booth #2210.
Curtiss’ presentation, “Collection and Control of Spectral Signatures in the Field,” promises to be a highlight of the conference.
With the Chinese New Year approaching, we thought it would be appropriate to post an article highlighting a recent and highly significant visit one of ASD’s co-founders made to Beijing, China.
Dr. Alexander Goetz was honored by the Chinese Academy of Sciences for his 30-plus years of the scientific and technological development of hyperspectral imaging. Hyperspectral imaging is now used worldwide in airborne and space-borne instruments to study the composition of the Earth’s surface, land as well as sea.
Dr. Goetz, a University of Colorado Professor Emeritus, gave a day-long set of lectures at a special two-day symposium on hyperspectral imaging held Dec. 1-2 at the Center for Earth Observations and Digital Earth in Beijing, China.
“You are surely the leading person in this field, producing nearly all critical achievements in the last 30 years,” Dr. Zhang Bing, Deputy Director of the Chinese Academy told Dr. Goetz.
Dr. Goetz replied, “While I very much appreciate the compliment, I cannot take full credit since I have had abundant help along the way from colleagues, students and co-workers at the NASA Jet Propulsion Laboratory, University of Colorado and ASD Inc.”
The Chinese Academy has a great interest in pursuing hyperspectral imaging as evidenced by the 200 faculty and students attending the symposium. The Chinese Space Agency has already sent a hyperspectral imager into lunar orbit and pursues land studies with airborne hyperspectral sensors. ASD Inc. has sold more than 400 portable spectrometer systems to China for a variety of remote sensing research applications.
Some of the latest research on small water bodies was done with an ASD FieldSpec HandHeld spectroradiometer (325-1075 nm). The research was conducted by Rahmatulla M. Igamberdiev, Goerres Grenzdoerffer, Ralf Bill, Hendrik Schubert, Martin Bachmann and Bernd Lennartz and has become available online this past week on Science Direct.
