The Maritime Chart Service has various control files that can be configured to meet your needs. Configuration options include the ability to expand the type of S-57 objects and attributes that the system recognizes if you've created a custom specification, S-52 presentation library customization to change default symbol colors, and the ability to alter the text format used to portray your data. There are also configuration options for the Maritime Chart Service that control how updates are applied, what coordinate system is used, and what size you want your symbols and text to be displayed.
Configuration settings related to International Hydrographic Organization (IHO) standards such as S-57, ENC, S-52, and S-63 are all configured to those specifications by default.
All configuration files are located at <ArcGIS Server installation drive>:\arcgisserver\directories\maritimeserver\maritimechartservice\.
Remarque :
This location can be found in the controlFilesDirectory property. Back up this location if you make any changes. Future installations overwrite this location.

S-57 data dictionary
The S57DataDictionary.xml file contains all the S-57 objects and attribute IDs as well as acronyms and descriptive values. It also contains a list of agency codes.
You can make localization changes to this file to display object and attribute names in the local language. You can also extend this file to include new objects, attributes, and enumerations for unpublished product specifications.
Remarque :
The map service must be stopped and restarted for changes to the S57DataDictionary.xml file to be recognized by the service.
Server configuration
The ServerConfiguration.xml file provides support for various coordinate systems, display parameters, Web Map Service (WMS) layer names, custom symbology, and automatic update support.
Coordinate system users
Maritime Chart Service supports projection in real time with more than 5,000 EPSG codes. The coordinate system is set to 102100 (Web Mercator Auxiliary Sphere) by default.
The crs.xml file in the controlFilesDirectory contains all the supported EPSG codes.
Conseil :
If you do not expect your clients to request different projections, it's recommended that you set your EPSG value to the required coordinate system. If you expect to support multiple projections, such as several UTM zones, it's recommended that you use EPSG = 4326 (WGS 84) to optimize performance.
Customize your crs.xml file
There are two overrides that can be used in the crs.xml file: WGS84Bounds and Axis Order. WGS84Bounds allows you to override the extent of the projection. The default values used by the projection engine are from https://spatialreference.org. In many cases, users want values that correspond to those published on https://epsg.io or custom values for their specific situation. Axis Order is used to override the y- and x- axis directions.

</PROJCS>Consider the following:
- The newly created .senc file contains the set CoordinateSystem value in the name.
- To change projections, you must modify the CoordinateSystem value, which is set to 102100 (Web Mercator Auxiliary Sphere) by default.
- S-57 datasets that fall outside the coordinate system boundary are not generated, and a warning message is written to the log file.
Complete the following steps to customize your crs.xml file:
- Open the ServerConfiguration.xml file and modify the CoordinateSystem value.
- Save the changes.
Remarque :
The map service must be stopped and restarted for changes to the ServerConfiguration.xml file to be recognized by the service.
- Stop the map service.
You don't have to delete your existing .senc files. They are deleted and re-created automatically by the service.
- Start the map service.
The .senc files are re-created with the new coordinate system. The CoordinateSystem value is in the name of the .senc file for reference.
WMS layer name
The WMS layer name is S57 by default. This value can be changed by updating the WMSServiceLayerName value in the ServerConfiguration.xml file.
- Open the ServerConfiguration.xml file and modify the WMSServiceLayerName value to the name you want to use for the WMS layer.
- Cliquez sur Enregistrer.
- Stop the map service.
- Start the map service.
Remarque :
The map service must be stopped and restarted for changes to the ServerConfiguration.xml file to be recognized by the service.
Enable Custom symbology
By default, S-52 symbology is applied during .senc file creation. The CustomSymbology value must be modified to convert your datasets using custom symbols (SVG) instead of traditional S-52 symbols for features with lookup values in the CustomSymbolMap.xml file.
Learn how to enable custom symbology
Learn more about the custom symbology file structure
- Open the ServerConfiguration.xml file and modify the CustomSymbology value.
- Cliquez sur Enregistrer.
- Stop the map service.
- Start the map service.
Remarque :
The map service must be stopped and restarted for changes to the ServerConfiguration.xml file to be recognized by the service.
If you already have .senc files built, you need to manually delete the .senc files before restarting the map service. Otherwise, the symbology changes are not applied. It is recommended that you stop the map service to remove any locks before deleting the .senc files.Enable AutoCellUpdate
The AutoCellUpdate property allows you to automatically apply dataset changes without having to stop and restart the service. This feature allows you to configure 24/7 support. The Maritime Chart Service is installed with this setting turned off by default. Before turning this setting on, you should understand your dataset update strategy and determine how long it takes to copy a 5 MB file across your network.
Once the AutoCellUpdate property is enabled by setting use="true", the Maritime Chart Service detects whether there are any changes to your datasets folder. Once a modification is detected, the same logic that's used when the service is started is run against the datasets folder. This detects what dataset changes have occurred and updates the service’s .senc and find.dat files while the service is still running. Users only notice the change when the display is refreshed or when search or identify is used on the dataset that is being processed.
The delaySeconds property sets how long the Maritime Chart Service waits before running its logic. For example, if set to 10 seconds, once the Maritime Chart Service detects a change to the datasets folder, it waits 10 seconds before running its logic. If another change is detected before the 10-second delay, the delay starts over. Once it reaches the delaySeconds count value, it processes the changes. Each file that is copied to the datasets folder counts as a change. For example, if you copy 10 files at once, each file restarts the count as it's copied.
If you don't set a large enough delaySeconds value and the dataset file takes longer than the setting to copy, Maritime Chart Service cannot process that dataset. This is no different than manually starting the map service before you finish copying data into the datasets folder. It's recommended that you set the delaySeconds value by at least a factor of 3 based on how long it takes to copy a single 5 MB .000 file into the datasets folder from your staging location.
- Open the ServerConfiguration.xml file and modify the AutoCellUpdate settings.
It should look similar to the following:
<AutoCellUpdate use="true" delaySeconds="10"/> - Save the changes.
- Stop the map service.
- Start the map service.
The auto cell update function is implemented once the map service is restarted.
Remarque :
The .senc files are not re-created for this change unless new S-57 datasets were added to the datasets folder while the service was shut down.
Display frames and S-52 color tokens
The color for Maritime Chart Service dataset frames is red, and the color for Custom Chart Builder (CCB) dataset frames is magenta by default. In the ServerConfiguration.xml file, there are two settings: one for Maritime Chart Service named DisplayFramesMCS and another for Custom Chart Builder (CCB) named DisplayFramesPOD.
The color token values added to these properties are set using standardized S-52 color tokens. You can modify any color token value and restart your map service to see the changes. The display frames property found in your S52DisplayProperties.xml file is the setting that allows you to turn your dataset frames on or off.
All S-52 color token values can be found in the DAY.clr file under your colcalib folder located in the controlFilesDirectory location, which is <ArcGIS Server installation drive>:\arcgisserver\directories\maritimeserver\maritimechartservice. This location is in your controlFilesDirectory property. Back up this location if you make any changes. Future installations may require you to overwrite this location.
Remarque :
To use the override values, you must set IntendedUsageOverrideCodes use = true and restart your map service.

Zones of Confidence diagram colors
To create a Zones of Confidence diagram using Custom Chart Builder (CCB), you can set RGB color values.
There are six settings in the ServerConfiguration.xml file, one for each CATZOC category. You can modify any color token value and restart your map service to see the changes.
- Open the ServerConfiguration.xml file and modify the ZOCColors CATZOC settings.
<CATZOC code="1" description="A1" color="#59FCD4" colorDescription=''/> <CATZOC code="2" description="A2" color="#50E4DB" colorDescription=''/> <CATZOC code="3" description="B" color="#48CCE2" colorDescription=''/> <CATZOC code="4" description="C" color="#3FB4EA" colorDescription=''/> <CATZOC code="5" description="D" color="#379CF1" colorDescription=''/> <CATZOC code="6" description="U" color="#2f89f5" colorDescription=''/> - Cliquez sur Enregistrer.

S-52 display properties
The S52DisplayProperties.xml control file allows the system administrator to configure how the service behaves based on the S-52 standard.
Remarque :
The map service must be stopped and restarted for changes to the S52DisplayProperties.xml file to be recognized by the service.
Display parameters
There are many S-52-based mariner settings and other parameters that the client apps can pass to the service, which allows the display to be modified independently by each client request. You can download sample Maritime Chart Service sample widgets for ArcGIS Web AppBuilder from GitHub that show how to use these parameters. When the service is started, the settings in S52DisplayProperties.xml are used by default. The sample app displays those values, along with additional values that can also be found in the S52DisplayProperties.xml file.
Remarque :
Some parameters in the S52DisplayProperties.xml file may not be supported by the sample widget.
All parameters are defined in the S52DisplayProperties.xml file along with additional comments. Following is an example of Display Light Sectors:<Parameter name="DisplayLightSectors" type="E" default="2" value="2">
<Description>Display light sectors</Description>
<Comments>New at 10.6.1 Patch 2 </Comments>
<ExpectedInput code="1" value="False"/>
<ExpectedInput code="2" value="True"/>
</Parameter>
| Parameter | Description |
|---|---|
Parameter name | Name of the parameter that is passed to the service. |
Type | E—Enumerated list. F—Floating point value can be used. L—List value when more than one value can be passed to the service. |
Default | Default value that S-52 recommends if the parameter is referenced in the S-52 standards. |
Value | Value that is used by the service when it starts. This value can be overwritten by the client. |
ExpectedInput | Used when type is E or L. Code—Value that is used by the service. Value—Description of the code that is passed to the service. |
Additional parameters include the following:
- Area Symbol Size
- Area Symbolization
- Attribute Description
- Color Scheme
- Compass Rose
- Dataset Display Range
- Date Dependency Range
- Date Dependency Symbol
- Deep Contour
- Display AIO Features
- Display Bathymetric IENC

- Optional Deep Soundings
- Point Symbolization
- Remove Duplicate Text
- Safety Contour
- Safety Depth
- Shallow Contour
- Text Groups
- Text Halo
- Text Size
- Two Depth Shades
Remarque :
The Data Frames parameter value is set to automatic by default. When set to automatic, the intelligent zoom chooses the best charts for the area based on the current reference scale and displays the charts at that scale. If a chart is the best one for the area but has a reference scale lower than the chart minZoom value, the cell extent is drawn instead of the chart. The client can override this and turn all cell extents on or off using the client-side parameters. When turned on, all dataset extents are visible regardless of your reference scale.
Remarque :
The Compass Rose parameter value is set to False by default. This does not display any compass rose points for MAGVAR point features. S-52 symbology is also used by default. If you want to see MAGVAR point features as INT1 compass rose symbols, the Compass Rose parameter value must be set to True in the S52DisplayProperties.xml file; then the service can be restarted. When a compass rose is displayed, the deviation from true north is calculated based on the current date.
Conseil :
It's recommended that you remove the IntendedUsage and ExpectedInput parameter values from the S52DisplayProperties.xml file that won't be loaded into your service. For example, if you're only going to publish ENC datasets, remove those values for AML and IENC that are not used by ENC products.
The following is an example of what gets passed to the service by the client: http://<machine.domain.com>/arcgis/rest/services/SampleWorldCities/MapServer/exts/MaritimeChartService/MapServer/parameters?f=json&full=true. This URL can be accessed by using the Maritime Chart Service parameter operation..
View over groups
The S52DisplayProperties.xml file comes with various examples of how to configure feature layers in a service layer. The ParameterGroup name property ViewOverGroups is used by default. You must ensure all other samples have a different name.
The concept of view over groups comes directly from S-52 and can be configured and extended in the same way as S-52.
Remarque :
With the release of AML 1.1.3 Portrayal Specification, a new set of view groups has been defined. To use these groups for your S-57 AML datasets, you must change the ViewOverGroups Parameter Group setting to use ViewOverGroups_AML_Sample. You must also change the name of ViewOverGroups_AML_Sample to ViewOverGroups and rename your existing Parameter Group setting something other than ViewOverGroups. The AML view groups contain 23 layers, while the default view group contains eight layers.
Remarque :
You must restart your map service after making changes to the S52DisplayProperties.xml file.
<ParameterGroup name="ViewOverGroups" defaultVisibility="false">
<ViewoverGroupsDescription>This example includes all view groups into 8 feature layers</ViewoverGroupsDescription>
<Parameter name="0" type="E" default="2" range="11000-11060,21010-21060,31000-31080">

Description | This text is displayed on the contents tab or in the table of contents. |
Default visibility options for View Over Groups
| Option | Description |
|---|---|
Set to True for a View Over Group containing only one feature layer. This is the default setting. | It's expected that feature layers can be turned on or off only. All other S-57 service layer information is displayed unless you turn the parent layer off. For example, if you turn off soundings, all other information in the service layer is displayed. This option allows you to quickly create a single feature layer that can be turned on and off without the need to define other feature layers. |
Set to True for a View Over Group containing more than one feature layer. | This option produces the same behavior as the default setting. The exception is when all view groups are represented in the View Over Group, whether it consists of one or more feature layers. When you turn the last feature layer off, it's still displayed unless you turn off the parent layer. To avoid this, ensure that you set defaultVisibility to False when you include all view groups in your View Over Group. |
Set to False for a View Over Group containing only one feature layer. | When the feature layer is turned off, the parent layer is also turned off, since nothing should be displayed. This option should be used when only one feature layer, for example, navaids, is to be displayed from the data. Only the data from the feature layer is displayed; no other data from the service is displayed. |
Set to False for a View Over Group containing more than one feature layer. | When all the feature layers are turned off, the parent layer is also turned off. This option should be used when one or more feature layers are required. An example is having a feature layer for soundings and a feature layer for navaids, which are the only two feature layers displayed. All other S-57 service layer information is suppressed. |
A View Over Group is defined with no feature layer information. | Set the defaultVisibility setting to False. Otherwise, the feature layer node does not turn off the layer. Remarque :If the setting is not included, it defaults to True. |
View group descriptions (View Group)
According to S-52, S-57 objects are grouped into View Groups. The View Group IDs are what the View Over Group range values are set to. These View Group IDs are related to entries in your .dic files.
The .dic files, which are located with the rest of your control files, are part of the S-52 Standard and control how features are displayed. These view groups can be configured as necessary to create View Over Group feature layers for your service.
For example, the ViewGroup for beacon contains five individual S-57 objects, but they are all controlled by one ViewGroup.<ViewGroup id="17020" Description="beacon"/>
<ViewGroupS57Objects Code="" Acronym="BCNCAR" Description="" Dictionary="psymrefs" Comments=""/>
<ViewGroupS57Objects Code="" Acronym="BCNISD" Description="" Dictionary="psymrefs" Comments=""/>
<ViewGroupS57Objects Code="" Acronym="BCNLAT" Description="" Dictionary="psymrefs" Comments=""/>
<ViewGroupS57Objects Code="" Acronym="BCNSAW" Description="" Dictionary="psymrefs" Comments=""/>
<ViewGroupS57Objects Code="" Acronym="BCNSSP" Description="" Dictionary="psymrefs" Comments=""/>
If you want to turn on or off each beacon type individually, you must create View Groups for each beacon type and modify the associated .dic files.
Special display parameters
The special display parameter settings allow an administrator to optimize the display based on the hosted S-57 datasets. These settings allow for fine-tuning, but they typically do not need to be modified.

</ParameterGroup>Chart
The chart setting controls when your dataset is displayed based on the S-57 dataset's scale and the view scale. The display of the S-57 datasets can be determined using the following formula, where X is your reference scale:
X = Dataset Scale / View Scale- If X is less than the minZoom value, the dataset is not displayed.
- If X is greater than the maxZoom value, the dataset is displayed as long as another dataset doesn’t have a better reference scale value.
- If X is in the range of the minZoom or maxZoom, the dataset is displayed.
By increasing the minZoom value to a larger number (for example, 0.28), you must zoom in closer before the dataset displays.
If two S-57 datasets fall in the minZoom and maxZoom range, the dataset with the smaller reference scale is displayed. For example, you have two S-57 datasets (A at 1:1,500,000 and B at 1:90,000) and your view scale is 1:587,862.
- Reference scale for A = 1500000/587862, which is 2.55
- Reference scale for B = 90000/587862, which is 0.153
Symbol, Line, and Area
The Symbol, Line, and Area properties all contain a scaleFactor as well as minZoom and maxZoom settings. Changing these values either increases or decreases the size at which your symbols draw. Once X (reference scale) is calculated, that value is multiplied by the scaleFactor. The new value is compared to the minZoom and maxZoom settings as follows:
- If X is less than the minZoom value, set it to minZoom.
- If X is greater than the maxZoom value, set it to maxZoom.
Text
The Text property’s scaleFactor as well as minZoom and maxZoom settings behave the same way as Symbol, Line, and Area settings. Changing these values either increases or decreases the size at which your text draws. The Text property contains two additional settings for removing duplicate text (removeDuplicateText) and removing the halo from around text features in all color schemes. When removeDuplicateText is set to true (the default setting), it removes duplicate text for features from S-52 text group 21 Names for position reporting, with the same S-57 object class name. If S-57 object class names are different, the duplicate text is not removed.
Modify display parameters
Complete the following steps to modify display parameters:
- Open the S52DisplayProperties.xml file and modify the necessary settings.
- Save the changes.
The map service must be stopped and restarted for changes to the S52DisplayProperties.xml file to be recognized by the service.
- Stop the map service.
- Start the map service.
The display parameters of your existing S-57 datasets have not been modified. Any new S-57 datasets that are added to the datasets folder display with the updated parameters.
If you want your display to be 1:1 as with an ECDIS, you must set your AreaSymbolSize, LineSymbolSize, PointSymbolSize, and TextSize values for minZoom and maxZoom to 1.
Configure blue light sectors
As of S-52 Presentation Library 4.0.2, the S-52 standard does not support the display of blue light sectors. According to S-52, light sectors with COLOUR = 5 must be displayed using the color token CHMGD (Magenta). With a minor configuration change, Maritime Chart Service can now display S-57 light sectors with COLOUR = 5 using a custom color token.
The custom color token is named LITBL and is found in the Maritime Chart Service .clr files used for the different color schemes, such as DAY, DUSK, or NIGHT. By default, Maritime Chart Service has the LITBL set to the same RGB values as CHMGD. If you want to display light sectors with COLOUR = 5 as blue, you need to modify the RGB values for the LITBL color token in each .clr file for your implementation.
Change the RGB values for LITBL
Complete the following steps to change the RGB values for the LITBL:
- Browse to the colalib folder.
The location of the colalib folder varies depending on your implementation. For example: <ArcGIS Server installation location>\arcgisserver\directories\maritimeserver\maritimechartservice\controlfiles\S52PresentationLibrary\colalib.
- Edit the .clr file:
- Search for the LITBL color token that is set to RGB value CHMGD by default.
- Update the RGB values to the color you want to use.
Refer to the CLR table structure below.
- Save the file.
- Repeat the process for each .clr file.
Remarque :
Updates to the .clr files require that the .senc files be rebuilt for the changes to be applied. Refer to the section on rebuilding the .senc files below.
CLR table structure
The color tables are defined in the S-52 PresLib Ed 4.0.2 Part 1 App A Colour Tables.pdf. The values in the color tables are used in Maritime Chart Service .clr files. The .clr table contains nine columns. The first five are defined in S-52 PresLib Ed 4.0.2 Part 1.pdf section 11.4.2 Color Definition CIE-Field. There are four additional columns (Red, Green, Blue, and Conversion Error) that are created during the conversion process from CIE to RGB. You must modify the red, green, and blue values.
The .clr table columns are listed below:
- Token—This value is referenced in the S-52 lookup tables. All features referencing this token use the defined RGB values.
- Color—The descriptive name; however, there are many versions of a color—some descriptive names are repeated but have different RGB values. This value can be modified if desired, and does not impact Maritime Chart Service.
- X—The x-coordinate value on the CIE color chart.
- Y—The relative luminance value (brightest white) on the CIE color chart.
- Luminance—The lightness value (CIE color system).
- Red—The red value for RGB color.
- Green—The green value for RGB color.
- Blue—The blue value for RGB color.
- Conversion Error—This value is ignored.
Rebuild the .senc files
Complete the following steps to rebuild the .senc files:
- Sign in as a server manager by launching https://gisserver.domain.com:6443/arcgis/manager.
- Click Services.
- Stop the map service with Maritime Chart Service capabilities configured.
- Delete the contents from <ArcGIS Server installation drive>\arcgisserver\directories\maritimeserver\maritimechartservice\sencs.
- Start the map service.
- Repeat these steps for each map service for which you modified .clr files.
