Hyperspectral Remote Sensing and Its Applications

摘要: data-cubes are then calibrated and corrected to produce reflectance files. These files analyzed spectrally results identifying species and/or stress levels, based upon ground truth spectra or coordinates previously gathered. The images geo-rectified made into GIS-ready levels also GIS vectors individually so that can be evaluated from flight flight, comparable year year. HAI flew 400 linear miles in the Kiski-Conemaugh Watershed for invasives identification. West Virginia University gathered via a handheld spectrometer. mission was search 13 compare volunteer data throughout watershed. conclusively located mile-a-minute, tree of heaven, garlic mustard, purple loosestrife, Norway maple, phragmites. second Catskill Mountains New York cooperation with Hampshire. two polygons determine hemlock locations health, on GPS by UNH. Results still pending but preliminary encouraging both classification health distributions being qualitatively appropriate. Despite lack conclusive these missions, have shown hyperspectral imaging will valuable detection delineation, especially bands flexibility this sensor flown Helicopter Applicators Inc. Hemlock woolly adelgid other forest pests, including species, problem our forests ecosystems. Surveying monitoring problems done at great cost money time. With use remote sensing, vegetation identification remotely, saving time surveying larger area. Hyperspectral Remote Sensing is process gathering spectral signatures remotely. Everything has its own signature, similar fingerprint, making each unique. Incorporated utilizes an AISA Eagle 1K system gather analyze signatures. (HAI) established 1974 as aerial application company, since branched field sensing. now radiometric infrared camera, three-chip digital daytime system. systems mounted helicopters gyrostabilized turrets. wider swath ability which allows it higher therefore more less time, while same better resolution than sensors. customized hardware software, offers full end product. To demonstrate this, involved management projects 2004. perform such provided GISready shapefile used acquisition.
