from Cuprite, NV
By Joe Boardman, AIG
AIG is pleased to release the first demonstration results from the HyMap USA
campaign (Click on the image above or here for a
full resolution image). The plots and images shown here map the occurrence of the mineral
buddingtonite at Cuprite, Nevada, a well-known test site. We believe this is the best-ever map of buddingtonite at
Cuprite. This isn't an easy task, because Cuprite has been the training ground for all imaging spectrometers for more than
The high signal-to-noise ratio and spectral fidelity of the HyMap
instrument, coupled with the precision geometric correction and atmospheric compensation developed by
AIG, give us world-beating results. We've mapped
buddingtonite at Cuprite with virtually every airborne scanner available and have never gotten results this good,
this fast, or this GIS-ready. It's truly the beginning of a new age in the availability of high-quality,
well calibrated, and precision-geolocated commercial hyperspectral data.
Take a look at the following images for the proof.
Figure 1 is a B/W image (10m spatial resolution) showing buddingtonite
occurences, many were previously unknown, even after fifteen years of intensive study by many investigators.
Figure 2. Full resolution (10m spatial
resolution) image of the B/W background image above with buddingtonite abundance levels
superimposed in color. High to low : red, green, blue, yellow, cyan, magenta, maroon. The JPG does
not do it justice! Note we are precisely geocorrected.
Figure 3 (Spectral Plot), above: Stacked HyMap spectra showing means of the various buddingtonite levels
from red=high to maroon=low. Note the mixing shown in the spectra. Clearly HyMap is detecting very low (2-3% abundance) buddingtonite pixels.
