Different visualizations of the same VNIR+SWIR hyperspectral image (of Wizard Island, Crater Lake, OR) draped over a lidar bare-earth digital elevation model. The variation in vegetation, snow, soil/geologic cover, and even water properties can be highlighted with different combinations of spectral wavelength images.

HSI on the Fly

One company details mapping applications of airborne hyperspectral imagery for agriculture, forestry, and resource mapping. By Patrick Burns and Scott Nowicki, PhD Remote sensing imagery has been collected with many different camera systems for many different applications over the past 50 years of the industry.  Visible remote sensing imagery provides interpretable information available to most...

Re-imaging Hells Canyon

A geospatial company helps prepare for an environmental impact statement by scanning and orthorectifying historic imagery. Hells Canyon, North America’s deepest river gorge, encompasses a vast and remote region with dramatic changes in elevation, terrain, climate, and vegetation. Carved by the great Snake River, Hells Canyon plunges more than a mile below Oregon’s west rim...
