S-57 is the electronic data transfer standard prepared by the International Hydrographic Organization (IHO) committee. The geodatabase model allows the user to import Electronic Navigational Charts (ENC) .000 files, which in turn provides the user with a highly accurate vector data set that is ideal as foundation data. Enabling added value to the .000 ENC files within a non-navigational environment. A generic nautical style sheet is also available for download. Please note that the symbology provided in the nautical style set does not correspond to S-52, it uses other navigation-oriented symbology.
The ESRI S-57 .000 ENC output file is not for use in marine navigation under any circumstances. Find information about the S57 data format under the ECDIS (Electronic Chart Display Information System) section. To find out more information about implementing with the S-57 model please visit the PLTS Nautical Solution website.
The NOAA Coastal Services Center created a tool for the automatic symbolizing of S-57 data. To get this tool visit the ENC Data Handler extension for ArcView 3.x and ArcGIS
