Converting polygons to points

With some product specifications, polygons may need to be captured as point features if they do not meet a requirement for the area features. For instance, built-up areas that are less than 20 square miles in area may need to be point features rather than polygons. The Production Polygon To Point allows you to add points to selected polygons from a single feature class.

When polygons are converted to points, the new point features are attributed in the following manner:

To expedite the conversion process, you can check the Simple check box, which prevents the Production Polygon To Point tool from calculating the feature angle. If this check box is not checked, the tool attempts to calculate the feature angle based on the longest segment on the polygon feature.

You can also choose to delete the polygon feature once it has been converted to a point. If the Delete Polygon check box is checked, the polygon feature is deleted once the point is created. If the check box is not checked, the polygon feature is not deleted.

步骤:
  1. Start ArcMap.
    提示提示:

    If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

  2. If necessary, load polygon features.
  3. On the main menu, click Customize > Toolbars > Production Editing.
  4. On the main menu, click Customize > Toolbars > Production Editing Advanced.
  5. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.
    注意注意:

    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.

    提示提示:

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

  6. Select the polygon features you want to convert to points.
  7. Click the Production Polygon To Point button Production Polygon To Point on the Production Editing Advanced toolbar.

    The Production Polygon to Point Tool dialog box appears.
