Surveying the Land Below: Hyperspectral Sensors go Airborne

Posted by Christopher Van Veen on Wed, Mar 14, 2012

Remote sensing is a very important application and perhaps the 'killer app' for hyperspectral imaging technology, particularly when it comes to airborne scientific techniques. With traditional roots in research, Headwall’s airborne hyperspectral sensors are considered an industry-standard research tool and have been routinely utilized for the study of such topics as climate change, environmental mapping and monitoring, biodiversity research, and studies of the effects of carbon emissions on the environment.
 
Headwall’s experience is that it often takes approximately 10 years for technology to roll out of the military/defense markets and be ready for commercial applications. One particular market note is the use of Headwall’s hyperspectral sensors for commercial remote sensing applications. This is proving to be a very large and significant market. For example, one of Headwall’s customers is VineView, a commercial airborne company located in California with a focus on providing precision agriculture information and aerial imagery to more than 800 vineyards in the western United States. Dr. Matthew Staid, President of VineView Scientific Aerial Imaging, is a leader in the utilization of hyperspectral imaging for the management of 'high-value crops.'  His company provides airborne remote sensing services to the winegrape industry consisting of hyperspectral, thermal, and infrared sensing data for precision farming and profitable agricultural management of vineyards.
 
VineViewVineView’s sensor needs are focused in two key areas – very high spatial resolution coupled with extremely fast data processing.  One key attribute of hyperspectral imaging is the amount of spectral and spatial data collected. To capitalize on the inherent value of hyperspectral data requires an ability to rapidly process all this data into a geo-rectified data set. Airborne hyperspectral solutions require high performance, aberration-corrected sensors as well as hyperspectral data-processing units to collect and 'package' this data.  These rapid data-acquisition capabilities allow VineView to expand aerial services beyond the winegrape industry and into areas such as citrus production, tree nuts, and cotton.
 
With the ability to 'see' beyond the visible spectrum of 380nm to 780nm, Headwall’s hyperspectral imagers are readily available and optimized for many different spectral regions to a base of worldwide customers. One common configuration deployed by a number of remote sensing customers is the use of a Hyperspec VNIR sensor and a Hyperspec SWIR sensor to cover the broad spectrum of 380 to 2500 nm.
