Remote Sensing Images
A wide variety of remote sensing data are available from airborne and satellite platforms along with supporting raster datasets such as digital elevation models, bathymetry, raster maps, and vector overlays.  This gallery showcases interesting results from selected sensors and datasets.


 

EO-1 Hyperion Image, Buck Island (off north shore of St. Croix), U. S. Virgin Islands acquired 21 January, 2002 and matching NOAA/USGS data.  Left image is true color composite of Hyperion bands 31, 20, 10 (0.66, 0.55, 0.45 micrometers) (RGB).  Right image is combined NOAA Bathymetry and USGS Digital Elevation Model (DEM).  Color coding for the bathymetry/DEM is from black to purple, dark blue, light blue, cyan, green, yellow, orange, red, white - low to high (deep water to shallow water, low elevation to high elevation).  Land is orange, red, and white.


 

EO-1 Hyperion images, Northern Grapevine Mountains (northern Death Valley), Nevada and California.  Data acquired 23 July, 2001 at approximately 30m spatial resolution.  Left image is a true color composite of Hyperion bands 31, 20, 10 (0.66, 0.55, 0.45 micrometers) (RGB).  Right image is a spectral mineral map using 40 short-wave-infrared (SWIR) bands in the 2.0 - 2.4 micrometer spectral range.  Key:  Green=muscovite #1, Blue=muscovite #2, Red=calcite, Yellow=dolomite, Purple=silica, Cyan=zeolites.


Northern Grapevine Mountains, Nevada.  Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) color composite,  2.1, 2.2, 2.35 micrometer bands (RGB) image as background. Clays and micas appear red, Carbonates, yellow.
