Modifying the page layout
Once the final rounds of quality control have been completed, the chart is ready to have the final elements added. The following steps are performed in the Layout View and include additions such as chart numbers, title blocks, notes, scale bars, logarithmic bars, diagrams, agency logos, and other elements.
Data frames
This first section is optional. If, during the cartographic finishing process, you changed your projection, standard parallel, or standard meridian, it is important that you reapply the correct projection for your chart. If the chart's data frames are already in the correct projection, you can skip this section and move on to Database elements.
- Start ArcMap.
- Open the product map document.
- If necessary, add the Nautical Cartography toolbar from the main menu by clicking Customize > Production > Toolbar Settings > Nautical Chart Production.
- On the Nautical Cartography toolbar, click Grids > Grid Layout View.
- Click Yes on the Grid Creation Wizard Warning dialog box.
- If producing a multipanel chart, activate each data frame and repeat the steps in Creating interactive representation masks.
-
Adjust printer settings and select the appropriate paper size and plotter for the chart.
Most plotters allow you to select customized sizes, as long as one side does not exceed the width of the paper in the plotter. If producing a multipanel chart, position the data frame in the appropriate location on the page.
- Click the Save Edits button .
Database elements
Adding surround elements
Once the data frame is properly set on the page, surround elements can be added to the layout. If you are using the sample nautical product library, your database element library comes with some preconfigured elements. Follow the steps below to add them.
If you are not using the sample nautical product library, you need to create your own elements. You can simply create them in each map document as needed, or create them in one map document and save those elements to your database element library for use on all chart products.
- If necessary, switch to the Layout View.
-
Use the Zoom In button on the Layout toolbar to zoom to the area where the first item will be added.
Note:
Do not use the standard Zoom tools from the Tools toolbar, because they will change the scale and extent of the chart.
- If necessary, add the Nautical Cartography toolbar from the main menu by clicking Customize > Toolbars > Nautical Cartography.
-
Click the Database Element button on the Nautical Cartography toolbar.
The Database Element dialog box appears.
-
For Database Location, click Browse and navigate to the location of your element library.
In many cases, this will be the same location as your product library.
-
Click OK.
If multiple element tables are found, you will be prompted to select the table name that contains your database elements before you can set the Database Element.
- Click OK.
- In the left panel of the dialog box with the tree view, expand Nautical > Paper Chart.
-
Choose one of the categories:
- Notes
- Scale Bars
- Choose the element you want to add to the layout.
-
Click Insert.
The element is added to the central area of the visible extent.
- Click Close to close the Database Element Library dialog box.
- Click the Select Elements button on the Tools or Draw toolbar.
- Click the newly added element to select it and drag it to an appropriate location.
- Repeat steps 4–14 to add more elements.
Editing surround elements
If you need to edit the elements, follow the steps listed below.
-
Double-click the element, or right-click it and click Properties.
Tip:
You may need to right-click and click Ungroup selected elements to be to able edit their properties.
The Properties dialog box appears.
- If necessary, click the Text tab to edit the text.
- Click Apply to view your changes.
- Click OK to accept your changes and close the dialog box.
- Click the Save Edits button .
Masking surround elements
In some cases, there may be less important information that needs to be masked for some of the elements (such as nonessential topography contours and other land features not essential to navigation). In these situations, follow the steps below.
-
On the Draw toolbar, click the drop-down arrow next to the Rectangle tool and do one of the following:
To create a rectangular mask
Click the Polygon tool and click and drag to create a rectangle to use as a mask
To create a mask for irregularly shaped elements
Click the Polygon tool and click to add points and create the shape of your new polygon graphic, then double-click to finish drawing
-
Right-click on the new rectangle graphic and click Properties.
The Properties dialog box appears.
-
For the Fill Color property, choose an appropriate background color.
For example, if you are masking features behind a tide table that is placed over a land area, you should select the land area color for the fill color.
- Choose No Color for the Outline Color property.
- Click OK.
- Click the Select Elements tool on the Draw toolbar.
-
Click and drag the rectangle graphic so that it fits over the element you need to mask.
The new rectangle graphic will block your element, because it is currently drawing on top of it.
-
Right-click the rectangle graphic and click Order > Send Backward.
This will move the graphic below the element so that the element is visible but the features below it, such as buildings and gridlines, are masked out and do not interfere with the legibility of the element.
- Click the Save Edits button .
Once you have finished creating new rectangle graphics and new polygon graphics, you can improve the legibility of your elements by grouping them with the elements so that when you move the element, the masking graphics move with them.
You can change the extent to be fixed by clicking View > Data Frame Properties. Verify that the reference scale is correct on the General tab. Choose the Fixed option for the extent on the Data Frame tab.
Most of the buttons on the Tools toolbar will be unavailable if the extent is fixed; use only the tools from the Layout toolbar to zoom in and out and pan.
Channel tabs and tide tables
Channel tabs and tide tables are used to show the depths of specific areas on a nautical chart for navigational purposes. The values found in these tables can often be pulled directly from the database. The graphic table element (GTE) is used to link values from your database to a table in your chart. In many cases, the data needed to create the table is not present in the database. In this case, you can still use GTE to configure the table's layout and add the values manually. The steps outlined below show you how to create a dynamically linked table, so that if changes are made to the data, the table will automatically update to reflect those changes.
- Open the map document.
- Verify that you are in Layout View.
- Using the Zoom In tool on the Layout toolbar and zoom in to the area where you want to add the table.
- Add the Nautical Cartography toolbar from the main menu, if necessary, by clicking Customize > Toolbars.

This activates the buttons on the right side of the dialog box.
-
Click Filters if you want to limit the records available for use in the table.
For example, you may want to limit the records available for use in your table to features that are dredged areas or those that have a specific name value, like "East River Channel".
The Data Filters dialog box appears.
There are several ways to filter the source data. You can filter based on a Selected Set or the Visible Extent, set a definition query in the feature layer properties and configure GTE to honor that query by checking the Honor Definition Query check box, or use an attribute or location filter.
For the purposes of creating a channel table, the following steps will focus on the use of the Attribute Filter.
-
Click Add Filter > Attributes Filter.
The Filter by attributes properties dialog box appears.
- Define your attribute filter by creating a SQL query.
-
Click OK to close the Filter by attributes properties dialog box.

For example, you may want to sort on OBJNAM for all records with a similar channel name to appear next to one another in your Data Items table. The records in the Data Items table will always appear in the order you are about to define.
-
Click OK after you have chosen a table field.
The Sort Options dialog box appears.
- You can sort the table items in ascending or descending order by clicking in the cell under the Sort Order header.
-
Click OK.
The Data Items are now sorted, and this order remains unchanged until it is changed using the Data Items dialog box.
-
Click OK to close the Data Items dialog box.
The Data Source tab is still visible.
To remove the unnecessary fields from the Data Items list, follow steps 33–36. Removing fields using the Table Fields Editor does not remove the fields from your source. It simply reduces the number of fields from the source layer that will be available to you in GTE's dialog boxes for this particular table.
If you do not want to limit the number of fields available for this table, skip steps 33–36 and go to step 37.
- Click the Table Fields tab.
- Click the row of the field that you do not need to retain for the purposes of creating this table.
-
Right-click the row and click Delete.

Source Diagram
A Source Diagram can be used to delineate where bathymetric, topographic, or other navigational data comes from. The Source Diagram consists of generalized versions of the land areas, graphic lines delineating source extents, and letters correlating the area to the source. The following steps explain how to use the existing land coverage layer, as well as a previous version of the Source Diagram.
Creating an annotation feature class
You may choose to create graphic text instead of creating an annotation feature class to store the labels for your source diagram. If so, you may skip this step.
- Start ArcCatalog.
- Browse to your product database.
- Browse to the CartographicFeatures feature dataset and click to select it.
- Right-click the dataset, then click New > Feature Class.
- Type a name, such as Diagrams_Anno, or some other name for your Source Diagram annotation feature class in the Name text box.
- Click the Type of features stored in this feature class drop-down arrow and choose Annotation Features.

- Choose the reference scale of the Source Diagram.
- Leave units as default.
- Click Next.
- Click Rename and type Source Diagram Annotation for the new name.
- Change the font and size if necessary.
- Click Next.
- Use the Default option.
- Leave all fields.
- Click Finish.
Creating a grid
The following steps outline the process required to create a grid for a source diagram.
- Start ArcMap.
- Open an empty document.
-
Load the feature class with land area.
This is NaturalFeaturesA for ENC data
- In the Table Of Contents window, click the List By Source button .
- If working in a versioned environment, right-click the database, click Change Version, then switch to an edit version.
-
Set the reference scale for the Source Diagram by clicking View > Data Frame Properties > General tab.
The reference scale needs to be one-tenth of the main panel. For example, a chart with the scale of 1:25,000 would have a Source Diagram with a scale of 1:250,000.
-
If necessary, open the Product Library window by clicking Customize > Production > Product Library on the main menu.
A tree view of the product library appears.
- Expand your product.
- Check the box next to the AOI.
- Right-click the AOI, then click Select.
- Click the ArcToolbox Window button on the Standard toolbar.
The ArcToolbox window appears.
- Expand the Nautical Tools toolbox.
- Expand the Cartography toolbox.
- Double-click the Make Grids and Graticules Layer geoprocessing tool.
Repeat all the steps to create the grids for the Source Diagram with the following modifications.
Note:The Make Grids and Graticules Layer tool requires you to have a feature dataset to write the output to. You may need to create a feature dataset in your product database before you continue.
-
Use the Source Diagram XML.
Note:
This XML is just a sample and may need to be adjusted for the scale of your chart.
- Save this second grid dataset separately from the main panel grids.
- Create a new feature dataset and give it a logical name. The tool will create the necessary feature classes.
- Use the custom scale option again and set the scale to one-tenth the scale of the main panel, or use the reference scale.
- After running the Make Grids and Graticules Layer geoprocessing tool, click the Grid Layout View button to update the projection, standard parallel, and meridian for the Source Diagram.
-
When finished, clear selected features.
Note:
If using a versioned environment, you will need to reconcile and post to the Default version.
Generalizing features
Because the source diagram is only one-tenth the scale of the chart it represents, you will need to generalize the layers being used in the source diagram. The following steps outline the process for generalizing features for a source diagram.
- Change the map to Data View.
- From the Selection menu, choose Select By Attributes .
- Click the Layer drop-down arrow and choose NaturalFeaturesA (or Land area polygon feature class).
- Click the Method drop-down arrow and choose Create a new selection.
- Choose FCSubtype from the list and double-click it so it appears in the expression box.
- Click the equal sign (=) so it appears in the expression text box.
- Click Get Unique Values.
-
Double-click 5 - LNDARE_LandArea so the expression now reads FCSubtype = 5.
Note:
You can type the expression if you already know the numeric value and have proper spacing.
-
Click Verify.
The Verifying expression dialog box appears.
- If the expression is verified, click OK.
-
Click OK on the Select By Attributes dialog box.
All land areas are now selected, and the dialog box closes.
-
Click Geoprocessing > Search For Tools.
The Search window appears.
- Type Simplify Polygon in the text box, then click Search.
-
Click the tool name.
The Simplify Polygon dialog box appears.
- Ensure that the above selected features (from step 2) are still selected.
- For the Input Features parameter, click and drag the NaturalFeaturesA feature class from the Table Of Contents window, or click the drop-down arrow and choose the NaturalFeaturesA feature class.
-
For the Output Feature Class parameter, map to your database the CartographicFeatures feature dataset and give the new feature class a logical name.
For example, if using the NaturalFeaturesA polygon feature class, call the new output feature class NaturalFeaturesA_Gen or NaturalFeaturesA_SD.
- For the Simplification Algorithm parameter, choose Bend_Simplify from the drop-down list.
-
For the Reference Baseline parameter, use a logical amount.
For example, a 1:25,000-scale chart would use 300–500 meters.
Tip:The tool can be run multiple times if the results are not the outcome you want.
- For the units, it is recommended that you use meters. However, use your discretion for the chart being produced.
- It is recommended that you leave the value for the Minimum Area parameter at 0. However, if you want the tool to keep smaller polygons set to a minimum area, select the numeric value and units.
- Leave the Handling Topological Errors parameter at the default value of NO_CHECK.
-
If you want to keep collapsed polygons as point features, leave the Keep collapsed points (optional) check box checked.
This will allow polygons that collapse on themselves as they are generalized to become points. These points are then created in a new feature class, stored at the same level as indicated by the output feature class.
- Click OK to run the tool.
- Both the user-defined polygon feature class and the similarly named point feature class are added to the Table of Contents.
- Examine the results of the generalization process.
-
If the results are not acceptable, the tool may be run again with the same input/output parameters, with the exception of the Simplification Tolerance Reference Baseline.
Note:
If the tool is run additional times, and with the same output feature class selected, it will overwrite the existing polygons in that feature class, not append to it.
- Remove the AOI polygon feature class.
-
Remove the original land areas (NaturalFeaturesA) feature class.
All that should remain are the grids and the generalized land area polygon layers.
If you did not have self-crossing polygons, skip the next section, Manually generating Source Diagram polygons, and continue with Symbolizing Source Diagram features. However, if you did have polygons cross themselves, continue with Manually generating Source Diagram polygons to determine which polygon features could be causing the problem.
Note:If using a versioned environment, you will need to reconcile and post to the Default version, and you will need to Register as Versioned the newly created feature class(es).
Manually generating Source Diagram polygons
This section is optional. When working with very detailed large-scale data, the Simplify Polygon geoprocessing tool can result in self-intersecting polygons, which will cause the tool to fail. In this case, follow the steps below to generate Source Diagram data. If the Simplify Polygon geoprocessing tool runs successfully with no errors in Generalizing features, then skip this step and move on to Symbolizing Source Diagram features.
- If possible, determine which polygon features are causing the tool to fail and run the Generalizing Features process on all NaturalFeaturesA features with a SQL selection set of FCSubtype = 5 and an additional statement excluding the offending polygon(s).
- If necessary, add the feature class from the output of the Simplify Polygon tool and the NaturalFeaturesA feature classes to ArcMap, placing the NaturalFeaturesA polygon below the Source Diagram feature class.
- Set a definition query on the NaturalFeaturesA feature class by opening the Feature Layer Properties dialog box, clicking the Definition Query tab and typing FCSubtype = 5, so that you only see the Land Area features.
-
Click the Production Start Editing button on the Production Editing toolbar.
Note:
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.
Tip: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.
- Set your Source Diagram feature class as the target layer.
- Using the land areas from the NaturalFeaturesA polygon feature class, digitize generalized polygons into your Source Diagram feature class as necessary.
- Click the Save Edits button .
Symbolizing Source Diagram features
- Click the Add Data button and add the generalized Source Diagram land areas polygon feature class to the Table of Contents twice.
-
Change the symbology for the generalized land areas so that
- One layer is symbolized with a fill color that matches the Agency Standard for land tint and no outline color.
- The other layer is symbolized with no color for the fill and the Agency Standard for coastline for the outline color.
- Click the Add Data button again and add the annotation feature class you created in Creating an annotation feature class (the suggested name was "Diagrams_Anno").
-
Click the Production Start Editing button on the Production Editing toolbar.
Note:
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.
Tip: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.
- In the Manage Features window, set the target layer to the annotation feature class.
- If necessary, add the Annotation toolbar to the ArcMap session by clicking Customize > Toolbars > Annotation and drag to a convenient location.
-
From the Annotation toolbar, the default settings should be
- Construction: Horizontal
- Text: Text
- Symbol: Source Diagram Annotation
-
On the Annotation toolbar, change the text to be the letter/number for the first source.
For example, A.
- Click the Construct Horizontal Annotation button .
-
Click in the data frame to place text.
What was entered in the toolbar will appear where the mouse is clicked, (not the word "Text")
- Click the Edit Annotation tool if necessary to modify the text size or position (click and drag or right-click the annotation and click Attributes).
- Repeat placing letters or numbers as needed for labels of the areas depicted in the Source Diagram.
- Click the Save Edits button .
-
Click the Stop Editing button on the Production Editing toolbar.
The geodatabase becomes uneditable. If you have made edits, you will be prompted to save the changes if you want.
- Open the Data Frame Properties from the main menu by clicking View > Data Frame Properties.
- Click the Data Frame tab.
- Click the Extent drop-down arrow and choose Fixed Scale.
- Type the scale of the Source Diagram (in this example, 250,000) in the Scale text box.
- Click the Frame tab.
- Click the drop-down arrow in the Border area and choose the 4.0-point line.
- Change the line color from black to Agency Standard for land tint.
- Click the drop-down arrow in the Background area and choose White.
- Click OK to apply.
-
Save the map document as a new one.
It will be added to the final layout in the next section. If using a versioned environment, you will need to reconcile and post to the Default version.
Adding the Source Diagram to the product map document
Now that the Source Diagram has been created, it needs to be added to the product map document through the following steps.
- Start ArcMap and open the saved Source Diagram map document.
- If working in an enterprise environment such as the NIS, click the List By Source button in the Table Of Contents window and ensure that all layers point to an editing version.
- From the Source Diagram map document, in the Table of Contents window, click the List By Drawing Order button .
- Right-click Layers on the Table of Contents window and click Copy.
- Start a second ArcMap session.
- Open the main chart panel map document in the second session.
- If necessary, switch to Layout View in the product map document.
- Click the Edit menu and click Paste.
- Once the data frame has properly pasted, close the Source Diagram map document without saving.
- Rename the newly pasted data frame Source Diagram in the product map document Table Of Contents window.
- If necessary, activate the Source Diagram data frame (right-click and click Activate).
- If necessary, click the Select Elements button on either the Tools or Draw toolbar.
- Drag the Source Diagram data frame to an uncluttered area of the chart.
-
Resize the data frame to be just a few points (roughly 1 mm) larger than the actual Source Diagram.
- When selected, grab one of the corner handles and hold down the SHIFT + ALT keys to maintain aspect ratio and to keep the data frame centered.
- You may need to use the standard Pan tool on the Tools toolbar to recenter the data frame over the Source Diagram.
-
Add a textual legend below the Source Diagram associating each letter with a source.
- From the Draw toolbar, select your font style and size.
- Click the Text button, then click in the space below your Source Diagram to type the text.
- Click the Select Elements button and adjust the size and position as necessary.
For example, a: U.S. Coast Guard Surveys from 1995 to 2001.
