To survey the ring tunnel, thousands of control points were shot with laser trackers and confirmed in order to maintain a reliable control network.

Neutrino Beam! Scanning a Ring Tunnel

The surveying challenges for construction related to a particle accelerator are exacting—but surprisingly familiar.  By Matteo Luccio Trillions of neutrinos from the sun and other celestial objects pass harmlessly and unnoticed through our bodies each second. These tiny particles are among the most abundant in the universe–a billion times more abundant than those that make...

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...
