Collecting Hydarea features

When collecting Hydarea features, you are required to code the CVL and CVH values along with ACC on each feature you create. Currently there is no automation tool for this.

When coding large depth areas that might be shoals or deeps, you need to find the highest or lowest sounding value. To help with this query, use the Select By Location tool on the Selection menu.

1. Start ArcMap.
2. If necessary, set up the DNC production environment.
3. Click the Production Start Editing button on the Production Editing toolbar.

   Hinweis:

   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.

   Tipp:

   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. Select the area you want to query.
