November's ASD Webinar - Quantitative Spectroscopy from Space

November 07, 2017

This November, the ASD webinar focuses on hyperspectral imaging, near infrared spectroscopy (NIRS), and multivariate calibration models (i.e. chemometrics), featuring ASD’s FieldSpec® 4 Hi-Res NG Spectroradiometer 

 

In this webinar, you will learn:

  • How the combination of hyperspectral imaging, near infrared spectroscopy (NIRS), and multivariate calibration algorithms (i.e. chemometrics), enables quantitative mapping of properties of the Earth's surface
  • The data that ground based reflectance measurements of materials can provide for remote sensing applications
  • How to apply quantitative chemometric calibrations to hyperspectral image data
  • Examples of successful applications

November's ASD webinar speaker is Dr. Brian Curtiss; Brian is one of the founders of ASD Inc. and currently serves as ASD’s Chief Technical Officer. He has over 30 years of experience in the fields of geology, spectroscopy and optical remote sensing. He received his Bachelor’s degree in Earth and Planetary Sciences from Washington University in St. Louis and his Masters and Ph.D. in Geochemistry from the University of Washington. In his current position, Dr. Curtiss applies his experience to the development of solutions to a diverse range of analytical problems in the areas of remote sensing and natural resources.

Spectroscopy In Analyzing Works of Art

October 24, 2016

In their investigation into the origin of the Selden Map of China, Kogou, et al. used several analytical techniques to characterize the map. ASD's LabSpec® 4 near-infrared (NIR) analyzer was used to characterize the pigment and binding medium. Future work will include the use of near-infrared analysis for direct analysis of the map itself. The non-invasive nature of ASD's LabSpec 4, plus the easily positioned fiber optic probe, means that they will be able to analyze any location on the map rather than being restricted to just a few spots or detached fragments. You can read Kogou, et al.'s research article, here

ASD's October Webinar Focuses on Interpreting Geochemical Conditions on Mars

October 04, 2016

Our 2016 webinar series focuses on one ASD spectroscopy application each month.

If you haven't watched our previous webinars, please visit our webinar recordings page to see what you have missed! Some of our past webinar topics include: NIR, Metamorphic Petrology, and Remote Sensing, On-orbit Sensor Absolute Radiometric Calibration for Earth Remote Sensing, and Adventures in Albedo.

This October, our spectroscopy webinar focuses on the specific application of terrestrial analog studies and geochemical conditions and features ASD's TerraSpec® Halo Mineral Identifier

In this webinar you will learn about:

  • Terrestrial analog rover simulations using a VNIR field-portable spectrometer in remote Utah as a useful tool in refining Mars rover operational strategies
  • On being a "human rover" - science team protocols, targets of interest and data collection
  • Using terrestrial analog sites to reconstruct the geologic history of Mars
  • Investigating diverse hydrothermal deposits with Mars analog instrumentation

August 23, 2016

Our 2016 webinar series focuses on one ASD spectroscopy application each month.

If you haven't watched each of our previous webinars, visit our webinar recordings page to see what you missed. Some of our past topics include: NIR, Metamorphic Petrology, and Remote Sensing, On-orbit Sensor Absolute Radiometric Calibration for Earth Remote Sensing, and Adventures in Albedo.

This September, our webinar focuses on the application of soil characteristics. 

In this webinar you will learn:

  • How (and why) water alters the spectral reflectance of soil
  • The importance of the location of water in the soil
  • Nutrient and organic matter analysis of soil
  • UAS sensor calibration using an ASD instrument
  • Groundtruthing a UAS sensor using an ASD instrument

Interested in sensor calibration? Join us for our April webinar!

March 31, 2016

This April, our webinar focuses on the specific application of Sensor Calibration.

Earth-observing sensors provide measurements for a wide range of climate and environmental studies. It is critical that these sensors and associated data products remain calibrated in order to achieve synergy among coexisting sensors as well as temporally throughout generations of sensors.

Evaluation of neural network classifier with VNIR spectroscopy for early detection of CCCVd in oil palm - a Goetz student's summary

September 22, 2015

Kamlesh Golhani, a recipient of the Alexander Goetz Instrument Support Program award earlier this year, recently published the preliminary results he obtained using a HandHeld 2 spectroradiometer for the early detection of CCCVd in oil palm. This summary also included assistance from Siva K Balasundram, Ganesan Vadamalai, and Biswajeet Pradhan.

Going beyond spectral vegetation indices...

December 23, 2014

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.
