S57 Charts

Freeboard-SK is able to display S57 ENC charts that have been converted to vector tiles with s57-tiler. (See the README for instructions how to create the vector tiles from downloaded S57 ENC's.)

See Open CPN chart sources for a list of locations to source charts.

Note: Only unencrypted ENC's are supported (no S63 support).

Experiments:

Features that are not ready for "prime time" are made available as experiments.

To make experimental features available from within the Freeboard-SK user interface, you need to ensure the Experimental Features option is checked in Settings.

Note: Some experiments will require configuration of Freeboard-SK via the Plugin Config screen of the Signal K Server Admin UI.

System Requirements:

Freeboard-SK requires _Signal K Server Version 2.0 or above.

The following features require that the Signal K server have plugins / providers installed to service the following paths:

• resources/charts - Ability to view charts.

• navigation/anchor, notifications/navigation/anchor - Ability to set anchor alarm and display notifications.

• notifications/environment/depth - Display depth notifications.

• signalk/v1/playback (Playback API) - Replay of recorded vessel data.

• vessels/self/track - Display of vessel track stored on server.

• vessels/self/navigation/course/calcValues - Display of calculated course values such as DTG, XTE, etc.

Recommended Plugins:

The following plugins are recommended for installation on the Signal K Server to enable full functionality:

• @signalk/course-provider (Course calculations e.g. XTE, DTG, etc.)
• @signalk/charts-plugin (Mapbox tiles chart provider)
• signalk-pmtiles-plugin (ProtoMaps chart provider)
• signalk-anchoralarm-plugin (Anchor alarm settings & notifications)
• signalk-simple-notifications (Depth alarm notifications)

Development:

Freeboard-SK is an Angular project.

It is recommended that the Angular CLI be installed globally npm i -g @angular/cli@latest prior to following the steps below.

1. Clone this repository.

2. Run npm i to install project dependencies.

3. Run npm start or ng serve to start a development web server and then navigate to http://localhost:4200/ to load the application. The application will automatically reload once you save changes to any of the source files.

Note:

The Freeboard-SK application will look to connect to a Signal K server at the ip address:port contained in the url of your browser.

In development mode you are able to specify the Signal K server host address and port you wish to connect to by editing the DEV_SERVER object in the src/app/app.info.ts file.

DEV_SERVER { 
    host: '192.168.99.100', 
    port; 3000, 
    ssl: false 
}

Note: These settings apply in Development Mode only!

They will NOT apply when using Production Mode, the generated application will attempt to connect to a Signal K api / stream on the hosting server.

Building a Release:

Building the Application:

To build all components of the application (plugin and webapp) ready for release use the npm run build:prod command.

Building components individually:

• To build only the webapp use the command npm run build:web.
• To build only the helper plugin use the command npm run build:helper.

Built files (for deployment) are placed in the following folders:

• /public (Freeboard-SK web app)
• /plugin (Freeboard-SK plugin)

Building the NPM package:

To build the NPM package use the npm pack command to:

1. Execute npm run build:prod
2. Create the NPM package (.tgz) file in the root folder of the project.
