About this asset

This S-57 format Electronic Navigational Chart for San Francisco Bay provides essential coastal and marine survey data for GIS. The dataset contains comprehensive S-57 formatted information for the San Francisco Bay region, identified as cell US5CA13M. It encompasses critical geographic features including precise shoreline geometry, bathymetric data, and established aids to navigation. This digital chart serves as a technical foundation for mapping coastal environments, providing accurate spatial references for marine infrastructure, harbor planning, and large-scale site analysis. The data is structured to facilitate seamless integration into GIS software, ensuring that all nautical features, depth soundings, and maritime boundaries are georeferenced correctly for professional maritime and civil engineering applications.

The download is a 922 KB file containing .ZIP files.

Professionals should ingest this S-57 file into GIS software or CAD platforms with integrated geospatial capabilities to project the data onto local coordinate systems. Ensure that all coordinate transformations are verified against project-specific survey data before finalizing any site layouts or infrastructure alignments in coastal project environments.

This chart is intended for coastal engineering, marine infrastructure planning, and large-scale site assessment within the San Francisco Bay area. It is particularly useful for architects and civil engineers working on waterfront developments, pier reconstructions, or environmental impact studies. By providing accurate bathymetric and navigational context, the data supports early-stage feasibility analysis and site masterplanning. It pairs effectively with local topography surveys and aerial imagery to build a complete picture of the project site's maritime and coastal constraints.
