You can export your changes to the S-57 format once you have compiled your new AML product or have made the necessary modifications to your existing AML product and verified your data. Exporting to S-57 is performed on your production database. Perform the following steps for exporting, publishing, and packaging your product for display in a Warship Electronic Chart Display and Information System (WECDIS).
Reconciling and posting changes to DEFAULT
All your data changes from your child version of DEFAULT need to be posted back to DEFAULT before the edits are exported to S-57. This is performed through reconcile and post operations; however, ArcGIS for Maritime: Charting uses its own Nautical Post command. The Nautical Post tool automatically replaces the standard Post tool located on the Versioning toolbar in ArcMap and also appears on the Nautical S-57 toolbar.
- Start ArcMap.
- Click the Production Start Editing button on the Production Editing toolbar.
- On the main menu, click Customize > Toolbars > Nautical S-57.
- Click the Reconcile button on the Nautical toolbar.
- Click the Nautical Post button on the Nautical toolbar.
Exporting to S-57
You can export content to the S-57 format after you have compiled the data for your new S-57 product or have made changes to the S-57 cell you imported. This can be accomplished using the Export Nautical Product command. The Export Nautical Product command builds and packages an S-57 file directly from the NIS database using the extraction queries for the product contained in the product library. The following processes will execute automatically.
- Extract data
- Clip data
- Group soundings
- Generate FE Name
- Generate or update primitives
- Calculate SCAMIN
Choosing the export type
When numerous modifications or updates have been applied to a product, a hydrographic agency usually issues a new edition.
An update contains minor changes to a published product, such as the removal of a buoy symbol or moving a sounding depth from one place to another.
A ReIssue is a regenerated New Edition file that contains updates to a certain point in time. For example, a New Edition cell could have twenty updates applied to it since its creation. Instead of loading all twenty updates into an ECDIS or WECDIS, a ReIssue will be created that is a New Edition file that contains all twenty updates. The ReIssue file preserves the update number so subsequent updates can be applied to it.
The New Dataset option is available only after you use the New Nautical Product wizard to create your product. This option creates a New Edition .000 file with an edition number of 1.
When an S-57 cell is no longer in use, a Cancel dataset type is generated. The cancel file changes the Edition number back to 0. The Update number increments by 1 and only consists of the DSID meta header information.
- 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.
-
Right-click the product you want to export to S-57 and click Export Nautical Product.
The ENC Export dialog box Export Information area appears.
- Click the Dataset Record Type drop-down arrow and choose the export type you want based on the 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 (...) in the Export Location area and browse to the location where you want to store your package.
