Swath derived bathymetric grids of Lostmans and Lower Shark Rivers, Florida (2015) in Esri ASCII grid format

High resolution bathymetry mapping of the coastal rivers and inland lakes along the Southwest coast of Everglades National Park (ENP) is greatly needed from the perspective of resource mapping and future research and hydrologic modeling efforts. To this end, bathymetric surveys of 8 coastal rivers were completed in 2004 as part of a cooperative project between the US Geological Survey (USGS) and the South Florida Water Management District (SFWMD). Recent analyses of geo_databases from the project in 2004 shows that Lostmans River and several segments of Shark River remained to be mapped. Completed surveys for these areas will provide and invaluable and complete set of bathymetric surveys of coastal rivers along the Southwest coast of ENP. This report serves as an archive of processed interferometric swath bathymetry data that were collected during one cruise (USGS Field Activity Numbers 2015_304_FA) in Lower Shark River, Florida. Geographic information system data products include: a 5 m_cell_size interpolated bathymetry grid surface and point data files. Also included in this archive are Geographic Information System (GIS) data products: gridded map data (in Esri binary and ASCII grid format), and a color_coded bathymetry map (in PDF format). Additional files include Field Activity Collection System logs, and formal Federal Geographic Data Committee (FGDC) metadata.
