Converting a part to a feature (Defense Mapping)

Cette rubrique s'applique uniquement à ArcGIS for Desktop Standard et ArcGIS for Desktop Advanced.

Production Mapping provides several functions for working with multipart features.

Examples of Multipart Polygon and Polyline Features

One way you can work with multipart features is to create a new feature that has the same geometry and attribute values as the part that is currently selected. For instance, rather than having three polygons as part of a single feature, you can convert one of the polygons to a single feature. This allows you to remove the part from the rest of the feature but still keep it in the map. When a feature is created this way, it retains the attribute values from the multipart feature, except for metadata items such as length and area.

Examples of features that have been created from part of a multipart polygon or polyline feature

Converting part of a multipart polygon to a feature creates a new feature with the geometry of the selected part. The geometry of the part is also removed from the original multipart polygon. The new feature has the attributes of the multipart polygon. For example, if you have a multipart island chain feature and convert one of the parts to a feature, the selected island would become a new island feature, and the part would be removed from the original multipart island chain feature.

Etapes :

1. Start ArcMap.
2. If necessary, load data in the map.
3. On the main menu, click Customize > Toolbars > Production Editing.
4. Click the Production Start Editing button on the Production Editing toolbar.
   Remarque :

   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.

   Astuce:

   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.

5. Select a multipart polygon or line feature.
6. Click the Edit Vertices button on the Production Editing toolbar.
7. Right-click a node on the feature and click Convert Part To Feature.

The selected part becomes a separate feature.
