Resource_Description:
USGS data release 2012-024-FA backscatter imagery from the Connecticut River (2013-003-FA_Bathymetry2m.zip). The zip file contains a folder with the 32-bit floating point GeoTIFF image (2012-024-FA_Bathymetry2m_NAVD88.tif) with a world file (2012-024-FA_Bathymetry2m_NAVD88.tfw). A depth-colored hillshade bathymetry 32-bit (4 8-bit channels RGBA) GeoTIFF image (2012-024-FA_Bathymetry2m_NAVD88_GeoTIFF3x.tif) with a world file (2012-024-FA_Bathymetry2m_NAVD88_GeoTIFF3x.tfw) and metadata files in standard formats are also included in the zip file. The pixel values in the depth-colored hillshade bathymetry image DO NOT correspond to depths. The pixel values of the 32-bit floating point GeoTIFF image are depth values.

Technical_Prerequisites:
The ZIP file contains a 32-bit Floating Point GeoTIFF image with a world file. To utilize these data an image processing or GIS software package capable of viewing a 32-bit floating point GeoTIFF image. Standard image viewing software cannot translate a 32-bit floating point GeoTIFF image. The depth-colored hillshade GeoTIFF image is a 32-bit (4 8-bit channels RGBA) which can be viewed in any image processing or GIS software package capable of viewing a 32-bit GeoTIFF image.
