Generating depth areas

Depth areas are S-57 objects used to depict depth ranges between contours in Electronic Navigation Charts (ENC). The Generate Depth Areas (Selected Feature) tool is used to create these depth areas. It updates depth areas that exist, creates depth areas as needed, and deletes areas that are no longer relevant based on a given extent and compilation scale. Boundaries of the extent are defined by selecting a polygon feature.

Nota:

Depth contours, closing lines, and group 1 features must exist prior to using the Generate Depth Area (Selected Feature) tool.

1. Inicie ArcMap.
2. Si es necesario, cargue datos en el mapa.

The following layers are required:

• SoundingP
• DepthsL
• PortsAndServicesA
• NaturalFeaturesA
• DepthsA

ClosingLinesL is optional and can be used to close boundaries.

Sugerencia:

When editing the NIS database, consider setting definition queries on the layers in the table of contents to match the scale band you want to edit.

3. On the main menu, click Customize > Toolbars > Nautical.
4. Type the compilation scale in the Compilation Scale text box and press Enter.

   You cannot use 0 (zero), negative values, or nonnumeric characters.

5. En el menú principal, haga clic en Personalizar > Barras de herramientas > Edición de producción.
6. Haga clic en el botón Iniciar edición de producción en la barra de herramientas Edición de producción.

   Nota:

   Las ventanas Administrar entidades, Crear atributos, Actualizar atributos o Atributos de metadatos aparecen automáticamente al iniciar la sesión de edición con la herramienta Iniciar edición de producción.

   Sugerencia:

   Si las ventanas Crear atributos, Actualizar atributos o Atributos de metadatos no aparecen al iniciar la sesión de edición, haga clic en el botón Mostrar/ocultar atributos de la ventana Administrar entidades.

7. If necessary, select the workspace you want to edit and click OK.
8. Click the Select Features button on the Tools toolbar.
9. Select the polygon you want to define as the extent you want to edit.

   For example, select the boundary of a hydrographic survey or create a new polygon.

   Nota:

   It is recommended that when defining the extent, you do not go outside the area that contains data. If you go beyond the area containing data, the tool may interpret the depth contours as open. The extent of the area of interest contributes to the forming of closed areas so depth information is available to attribute the depth area (DEPARE_DepthArea) feature output.

10. On the Nautical toolbar, click Nautical > Generate Depth Areas (Selected Feature).

    The Generate Depth Areas dialog box appears and is prepopulated with values from your data.

11. Accept the default value or type a value that is the highest contour in the Shallowest Depth Band or Drying Height text box.
12. Accept the default value or type a value that is the deepest contour in the Deepest Depth Band text box.
13. Leave the Merge Depth Areas check box checked if you want to merge the newly created depth areas with those that preexisted.

    For this to occur, the values for DRVAL1 and DRVAL2 attributes must match.

14. Haga clic en Aceptar.

New depth areas are created and existing depth areas are updated or deleted as needed.
