2019 USACE NCMP CASI Hyperspectral 16 Bit Imagery: Golovin, AK

The mosaic image contained in this file is comprised of multiple CASI 1500 scanlines that were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system along the shoreline of Alaska. CZMIL integrates a lidar sensor with topographic and bathymetric capabilities, a digital camera, and a Itres' CASI-1500 hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. The CASI-1500 imagery was collected at an altitude of 400m, a ground swath of 300m and at a resolution of 1m by 1m ground sample distance (GSD). Native CASI-1500 imagery data is not generally in a format accessible to most Geographic Information Systems (GIS). Specialized in-house and commercial software packages processe the imagery data into GIS-compatible products for visualization and further analysis. Horizontal positions, projected in Universal Transverse Mercator (UTM), are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid. Individual image strips have been rectified and mosaicked into blocks commensurate with the collection blocks. The data file naming convention is based on the year, project, area name, product type, collection block, and survey altitude. These files have been separated and delivered by JALBTCX collection blocks. An example file name is "2019_NCMP_AK_03WVN2541_HSI.tif", where 2019 is the year of data collection, NCMP is the Effort under which data were collected, AK is the area of data collection, and "HSI" is the product type. The supplementary header file is of the same name.

These data were collected as a part of the National Coastal Mapping Program (NCMP) to obtain imagery of conditions of the beach and near shore

The data positions were obtained using post processed PPRTX methods. The horizontal accuracy of the CASI hyperspectral imagery operation is ±1 m, 2 σ. Gross offsets are likely due to DEM contraints and lack of detailed terrain where USGS NED data were used in the absence of CZMIL lidar data.
