Hyperspectral imagery for Hog Island, VA, 2013

High resolution hyperspectral imagery Hog Island, Northampton County, VA, collected on May 26, 2013 on behalf of the USACE Engineer Research and Development Center using the Coastal Zone Mapping and Imaging Lidar (CZMIL) system. CZMIL integrates a lidar sensor with topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities.  LiDAR data is provided as a separate VCRLTER dataset. Four data entities are included here: RADIANCE data across (a) 48 and (b) 96 spectral bands at 1 and 2 meters spatial resolution, respectively; and atmospherically-corrected FLAASH reflectance data (c & d) across the same bands and resolutions.  The 48-band data cover the spectral range of 369.1 to 1040.0 nm (+/- 7.1 nm) and the 96-band data cover a similar range of 360.4 to 1038.4 nm (+/- 3.6 nm).  Individual bands are described in the metadata for each data entity. Both the FLAASH reflectance and the radiance data have had a water mask applied to them; therefore no hyperspectral data is currently available for nearshore and offshore environments nor for deeper marsh creeks and ponds. FLAASH zip files also include the corresponding ENVI template files containing the FLAASH Atmospheric Model Input Parameters.
