e-Navigation Prototype Displays

Introduction

EPD (e-Navigation Prototype Displays) consists of two applications for demonstrating potential e-navigation solutions. An ECDIS-like shipside application and a shoreside application.

The applications are in Java and use OpenMap(tm) for presenting geospatial information, and JavaBeans(tm) as a component framework.

Prerequisites

Java 8
Maven 3

Building

mvn clean install

Running

Runnable jar files are located here

distribution/EPD-Ship-Singlejar/target/epd-ship-dist-X.Y-SNAPSHOT.jar
distribution/EPD-Shore-Singlejar/target/epd-shore-dist-X.Y-SNAPSHOT.jar

To run from command line

java -jar distribution/EPD-Ship-Singlejar/target/epd-ship-dist-X.Y-SNAPSHOT.jar

Folders with settings files are created in the home folder

<home folder>/.epd-ship
<home folder>/.epd-shore

Creating Windows EXE files

Windows executables can be created by using the following Maven profile

mvn clean install -Pexe

The executables will be located here

distribution/EPD-Ship-Singlejar/target/epd-ship.exe
distribution/EPD-Shore-Singlejar/target/epd-shore.exe

Eclipse development

Use M2 Eclipse plugin or use Maven eclipse target

mvn eclipse:eclipse

Virtual AIS transponder

The virtual transponder can provide a live anonymized AIS feed. The following settings can be used for the transponder:

Host:port: ais.e-navigation.net:8002 Username/password: anon/anon

Quick start

To be able to see AIS targets and possible own ship, the sensor should be configured. In the main window press the Setup button in the top and go to the Sensor tab. Choose either TCP or serial connection type for AIS and configure TCP host/port or serial port.

If a separate sensor is used for GPS this can be configured the same way.

If the AIS source is not a transponder providing own ship information, an own ship can be simulated by choosing a vessel target present in the AIS stream. On the bottom of the sensor tab enable Simulated GPS and enter MMSI. If the AIS source provides lots of targets, the targets shown can be limited by selecting a sensor range so targets farther than this distance away not will be shown.

Press OK and restart application.

Design

EPD uses a component based design to facilitate an event driven architecture. Functionality is encapsulated in components. Events come from sensor and user input.

Using components allows easy collaborative development as components can be developed independently. Components automatically identify each others in the BeanContext, so no hard wiring is necessary. Components can also be moved between different projects using the same component framework. E.g. OpenMap.

Contribution

Fork the project and make pull requests.

Try to use the component architecture as much as possible. Implement components and hook up to other components with the findAndInit method rather than hard-wiring. Try to follow the coding standards already used in the project and document within the code with Javadoc comments. For more extensive documentation use the Wiki.

ENC layer

EPD does not come with an ENC layer but with the possibility to add one as a plugin. Currently the only known OpenMap ENC layer is a commercial one from the danish company Navicon.

To use Navicon ENC layer with EPD-ship please follow the steps below

Contact Navicon sales regarding a purchase of their ENC/S52 rendering engine. Mention the following:
- To be used with DMA E-navigation Prototype Display
- Version for use with OpenMap 5
- If you are using a 64-bit machine, ask for 64-bit dongle drivers
After purchasing you will receive a SDK and a USB dongle. Unpack the SDK in a directory. The SDK should at least contain the following folders lib, native and data.
Run installer in native.
Place the lib folder in <home folder>/.epd-ship
Create the folder: <home folder>/.epd-ship/navion
Place the folders native and data in the newly created folder.
In on a 32-bit system. Remove native/keylock.dll and rename native/keylock32.dll -> native/keylock.dll
Copy <home folder>/.epd-ship/enc_navicon.properties to <home folder>/.epd-ship/enc.properties.
Edit <home folder>/.epd-ship/enc.properties and set charts location in enc.s57PathLocation.
Run application
Enter Setup -> Map and enable ENC. Restart.

Utilities

The module epd-util contains some utilities to use with EPD.

Route from AIS generation

A route file can be generated given an AIS file given MMSI number. Example:

java -jar epd-util/target/epd-util-0.1-SNAPSHOT.jar aistoroute -in ~/tmp/aisdump.txt -out ~/tmp/route.txt -mmsi 304913000
