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.

Ground Truthing and Calibration of UASs

August 30, 2017

 

Ground truthing and calibration of imagery obtained using unmanned aerial systems (UASs - also known as UAVs or drones)

The use of unmanned aerial systems (UASs) is growing rapidly in the field of remote sensing as a new and versatile tool for data acquisition in areas such as agricultural resource monitoring, soil characterization, and environmental monitoring. Specific examples where sensors mounted on UASs have provided useful results include water stress detection in agricultural crops, plant biomass and nitrogen content in crops and grasses, yield forecasting for crops like wheat and rice, rangeland management, leaf area index, NDVI and vineyard management.

UASs fill the gap between satellite imagery and ground-based spectroradiometers. One of the main benefits is that their low operating height enables the generation of very high spatial resolution imagery data for small areas, with some systems reaching resolutions of 1 cm per pixel. UASs also can have a shorter revisit period than satellite platforms and offer high temporal resolution and increased maneuverability to allow access to previously inaccessible areas or hazardous environments. Another benefit of UASs is the low operational costs compared with other methods.
