Editing data using unit conversion (Maritime Charting)
If you need to convert units, for example, between English and metric, ArcGIS for Maritime:Charting 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 for Desktop.
You can configure your own unit conversion and rounding rules using the product library workspace XML file that is included in 海事制表.
