Validating elevation points

The Validate Elevation Points tool compares an elevation point layer to a contour layer and reports discrepancies between the elevation values of the features. The tool only validates features within the current visible extent of your map. You must have both a point and a contour layer to validate, and the attribute field that contains the elevation value must be the same in both layers. The values compared are usually in the ZV2 field but may be stored in a different attribute for your data. You can specify the name of the field that stores the elevation values using the Contour Field Name Options tool.

If the elevation values for the contour and elevation points are stored in two fields that do not have the same name, the tool will not be able to validate the elevation point heights.

The following situations will return errors when the contours are validated:

手順:
  1. Start ArcMap.
    ヒントヒント:

    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.

  3. On the main menu, click Customize Toolbars Production Editing.
  4. On the main menu, click Customize Toolbars Production Contouring.
  5. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.
    メモメモ:

    ヒントヒント:

    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. Click the Validate Elevation Points button Validate Elevation Points on the Production Contouring toolbar.

    The Validate Top Spot Heights dialog box appears.

    Validate Top Spot Heights dialog box
  7. Click the Elevation layer (point) drop-down arrow and choose an elevation layer to use.
  8. Click the Contour layer (polyline) drop-down arrow and choose a contour layer.
  9. Click the Browse button Browse next to the Output Log File text box.
  10. Navigate to the location where you want the log file saved.
