Ground Truthing and Calibration of Imagery Obtained Using Unmanned Aerial Systems

April 28, 2017

The use of Unmanned Aerial Systems (UASs – also knows as UAVs or drones) 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 (Normalized Difference Vegetation Index) and vineyard management.

TerraSpec® Alteration Mapping

April 25, 2017

Geologists use ASD spectrometers such as the TerraSpec® 4 and the TerraSpec Halo to help define alteration halos around hydrothermal ore bodies. By using the TerraSpec to differentiate subtle shifts in mineralogies, geologists can identify alteration halos and map zones of advanced argillic, propylitic and potassic alteration such as at the Los Andes, Nicaragua project described below. This helps the geologist better understand the resource and focus drilling programs to optimize exploration time and costs.

Can Light Really Tell You If You Have the Right Medication?

April 21, 2017

The cost of pharmacy mistakes is high:

“Costco Wholesale will pay $11.75 million to settle Department of Justice allegations that the chain’s pharmacies improperly filled prescriptions.

Investigations were conducted by federal authorities in Washington, Michigan and California.

Costco was accused of filling prescriptions that were incomplete, lacked valid DEA numbers and were for substances beyond doctor’s scope of practice.”

Do Not Miss Out on the April Webinar! - EcoSpec Project

ASD customers are true adventurers and discoverers out in the field utilizing our scientific instruments for a multitude of different application uses. The quest to collect the most accurate data can lead to innovative and creative “solutions” involving the pairing of materials and technologies alongside of an ASD instrument in order to create for a data collection solution that is capable of achieving results.      

How to Create...Towards and for a Measurable Solution

April 14, 2017

Definitions of the word “create” include, “to cause to come into being,” and/or, “to evolve from one’s own thought or imagination, as a work of art or an invention.”1

ASD and Bonsai Attending the 10th EARSeL Workshop

April 06, 2017

ASD will be attending the 10th EARSeL Workshop in Zurich, Switzerland on 19-21 April along with partner Bonsai Advanced Technologies.

ASD is pleased to be sponsoring this event this year, especially as this year happens to be the 20th birthday celebration of EARSeL’s Special Interest Group on Imaging Spectroscopy!

This EARSeL special interest group encourages, “interdisciplinary discussions among specialists working with innovative Earth Observation methods and technologies.”1

Join ASD at The 2017 SPIE Defense + Commercial Sensing Conference

March 30, 2017

The leading global sensing and imaging event heads to Anaheim – and ASD will be there. We will be joining other professionals at The 2017 SPIE Defense + Commercial Sensing conference April 11 – 13 in Anaheim, California to demonstrate the use of the the FieldSpec® 4 Standard-Res portable spectroradiometer and the FieldSpec® HandHeld 2 hand-held spectroradiometer.

The Importance of Calibrating Your Remote Sensing Imagery

March 28, 2017

Author:  Susan Parks, ASD Remote Sensing Segment Manager

Most people using satellite or aerial imagery understand the importance of geometric calibration; you need to tie the pixels in the imagery to the corresponding coordinate locations on the earth so that you can use the imagery in mapping applications. This is also important for analyses such as change detection.

However, there is another type of calibration that you should be doing on your optical remote sensing imagery to ensure that you are getting high quality and useful results from your images. Accurate radiometric calibration is a critical component for successful imagery analysis.

Join ASD at the AAPG/ACE 2017 Conference

March 23, 2017

Top mine operations around the world already trust ASD’s TerraSpec® line of mining instruments for their critical mineral analysis measurements. Realizing potential applications of dispersive NIR in the petroleum industry, ASD is joining 6,800 professionals from more than 72 countries at the AAPG/ ACE 2017 conference this April 2 – 5 in Houston, Texas.

Material Measurement with NIR

March 21, 2017

Author:  Dan Shiley, Manager ASD SummitCAL Solutions Team

We are often asked questions like, “how do I measure my product using ASD NIR?” Of course my standard answer is, “it depends”. Since so much depends on the assumptions and conditions, I thought it would be useful to try to help clarify some of the things that proper material measurement depends upon.
