You can export your changes to the S-57 format once you have compiled your new ENC product or have made the necessary modifications to your existing ENC product and verified your data. You need to perform the following steps for exporting, publishing, and packaging your product for display in an Electronic Chart Display and Information System (ECDIS).
- Export to S-57.
- Publish the export version.
- Create an exchange set.
Exporting to S-57
This can be accomplished using the Export Geodatabase to S-57 tool. This tool builds an S-57 file directly from the NIS database using the extraction queries and the area of interest polygon for the product contained in the product library in order to filter the necessary features. The following processes execute automatically:
- Extract data
- Clip data
- Group soundings
- Generate FE Name
- Generate or update primitives
- Calculate SCAMIN
- Start ArcMap.
- If necessary, open the Catalog window by clicking Windows > Catalog on the main menu.
- From the S-57 toolset choose the Export Geodatabase to S-57 tool .
- Click the ellipsis button next to PL Workspace and browse to the product library containing the product you want to export.
- If the product library is an RDBMS, choose the schema owner from the PL Owner drop-down list.
- Choose the product to export from the Product drop-down list.
- Choose the type of export you want from the Export Type drop-down list.
Descriptions from the S-57 Appendix B Product Specifications IHO document.
- New Edition—A new edition of a dataset, including new information that has not been previously distributed by updates.
- Update—Changes some information in a dataset.
- Reissue—A reissue of a dataset, including all the updates applied to the original dataset up to the date of the reissue. A reissue does not contain any new information that has not been previously issued by updates.
- New Dataset—A new dataset where no ENC data has previously been produced for this area and for the same navigational purpose.
- Cancel—To delete a dataset, an update cell file is created, containing only the Dataset General Information record with the Dataset Identifier (DSID) field. The Edition Number (EDTN) subfield must be set to 0.
- Click the ellipsis button next to Output Location and browse to the location where you want to write the S-57 Export.
- If you want to export the data from the database other than the NIS the product is associated with, click the ellipsis button next to Source Geodatabase and browse to the database.
Publishing the exported version
Once your S-57 dataset file has been cleared through a third-party validation package, you need to publish the exported record to incrementally export S-57 dataset files. You can publish and unpublish export versions that reference the data you exported to an S-57 dataset file.
- Start ArcMap.
- If necessary, open the Product Library window by clicking Customize > Production > Product Library on the main menu.
A tree view of the product library appears.
- Expand Product Library and Products.
- Browse to the product you want to publish.
- Right-click the product and click Publish or View Metadata.
The Publish or View Metadata dialog box appears. It lists the metadata values for each published new edition or update, and exports.
- Right-click the edition or update record you recently exported and click Publish.
- Click OK on the message box that informs you the new edition or update number that was published.
- Click Close.
Creating an exchange set
Once you have exported and published your S-57 data, you need to package the S-57 dataset files into a valid S-57 Exchange Set. This allows you to view the Electronic Navigational Chart (ENC) datasets in an ECDIS for shipboard navigation. You can create a valid S-57 Exchange Set with the Create S-57 Exchange Set tool.
- Start ArcMap.
- If necessary, click Windows > Catalog.
- Click Toolboxes > System Toolboxes > Nautical Tools > S-57 Tools.
- Click on the Create S-57 Exchange Set geoprocessing tool.
- Click Browse next to the Input Directory parameter and choose the folder containing the S-57 files, associated text and images.
- Choose the layout format from the Layout Format drop-down.
- Choose a location to write the Exchange Set to using the Output Directory parameter.
The ENC_ROOT folder will be created at this location.
- Click OK.
