Sample hyperspectral imagery


SpecTIR has made available a number of airborne hyperspectral imagery data sets for research, training, and educational purposes. They will be available from the SpecTIR website and cover a variety of subjects. The data was collected with the ProSpecTIR VNIR/SWIR hyperspectral sensors, which are typically used to collect spectral and spatial information for applications such as long-term environmental monitoring.

The samples include the radiance and reflectance files, which are calibrated and navigated, so that they can be used as a GIS layer.

The samples include: Gulf of Mexico coastal National Wildlife Refuge wetlands prior to oil landing onshore, a sample of oil on the water at the Deep Water Horizon well head on 6th June 2010, agricultural crops and vegetation, geologic samples from Cuprite and Virginia City NV, coral reefs from the Red Sea Wetland and submerged aquatic vegetation from the Sacramento River Delta and Urban and urban vegetation imagery from Reno, NV.

These samples are significant because they demonstrate the practical uses of spectral imagery. The sensors are operated from small aircraft, and can be at any location in the world in a matter of hours or days. Once onsite they can capture information that makes it possible to detect and monitor minute changes to the environment, water, or vegetation. Over time, this becomes a very powerful mapping tool that can be used to manage responses to both man-made and natural disasters.

Mark Landers, SpecTIR's president states 'A clear cut example of the use of this technology is the images that we collected from the coastal wetlands of the Gulf of Mexico as the oil was heading for the shore in June of 2010. We were able to establish a baseline, prior to the oil, that can be used initially in the wetland vegetation damage assessment work, and in the long term will help to measure and guide the recovery efforts of the Gulf States.'
