Creating features using unit conversion (Maritime Charting)

When features are created in a nautical production geodatabase, if you have unit conversion values preconfigured in your product library, all the fields designated as unit conversion fields are converted based on the field input and the unit type selected on the Nautical Unit Selection toolbar. For example, if you create a linear BRIDGE feature and give the HORCLR attribute a value of 12, and your height unit (HUNI) value is set to Meters, all unit conversion fields are converted from Meters to their respected units based on the conversion value you have defined in your product library.

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.

步骤:

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.
   注:

   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.

   提示:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button on the Manage Features window.

4. On the main menu, click Customize > Toolbars > Nautical Unit Selection.
5. Click the HUNI drop-down arrow and choose the height unit.

   By default, this is set to Meters.

6. Click the DUNI drop-down arrow and choose the depth unit.

   By default, this is set to Meters.

7. Click the PUNI drop-down arrow and choose the positional unit.

   By default, this is set to Meters.

8. Choose the appropriate template from the Manage Features window.
9. Click the Create Attributes tab.
10. Click the cell next to the HUNI field and type the source value.
11. Click the cell next to the DUNI field and type the source value.
12. Click the cell next to the PUNI field and type the source value.
13. Click Apply.
14. Click in the data frame to create the new feature.

    The newly created features have their destination fields. For example, _M is populated with the converted value, and the _UC and _RR fields are also updated.
