Editing data using unit conversion

If you need to convert units, for example, between English and metric, ArcGIS Maritime provides a mechanism for configuring unit conversion and rounding rules, applying those rules for importing into the geodatabase, exporting to S-57 format, then editing and labeling in ArcGIS Desktop.

You can configure your own unit conversion and rounding rules using the product library workspace XML file that is included in ArcGIS Maritime.

1. Start ArcMap.
2. On the main menu, click Customize > Toolbars > Production Editing.
3. Click the Production Start Editing button on the Production Editing toolbar.

   Note:

   The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.
