ARCHIVED HYDROGRAPHIC SURVEY DATA:

The Galveston District Navigation Hydrographic Survey page hosts the most up-to-date survey maps and xyz datasets.  For all archived datasets, including initial storm response centerline-quarter survey data,  please visit the National Channel Framework (NCF) within the U.S. Army Corps of Engineers Survey & Mapping page.  Available data for download includes PDF maps, geodatabases, raw xyz, reports and metadata for all surveys.

ABOUT THE NCF:

Three representative survey and mapping datasets include the National Channel Framework (NCF) —an enterprise geodatabase of information on all 61 USACE-maintained high-tonnage channels —hydrographic surveys, which provide assistance in locating navigable channels, determining dredging requirements, verifying dredging accuracy, and maintaining harbors and rivers —and Inland Electronic Navigational Charts(IENC).
