Map Widget for Phoebus

This widget provides an interactive map for the Phoebus Control System Studio, allowing users to place markers and open related displays directly from the map interface.

Prerequisites

• Java JDK 21 (must match your Phoebus installation version)
• Apache Maven 3.9+
• Phoebus 5.0.5+
• Map tile server (see below)

Map Tile Server Requirements

This widget requires a map tile server to function.

You can run a local tile server using Switch2OSM or a similar solution. The default configuration points to a local server:

private static final String host = "http://172.28.41.114/hot/";

Tile URL format: {host}/{zoom}/{x}/{y}.png

Build Instructions

The widget uses the maven-shade-plugin to package all external dependencies (Gluon Maps, Attach libraries) into a single "fat JAR":

mvn clean package

The resulting JAR will be located at:

target/Map-Widget-0.13.0-SNAPSHOT.jar

Adding to Phoebus

This widget is designed as a plugin for Phoebus. For detailed deployment instructions, including custom launch scripts and classpath configuration, refer to the hello-widget README – the same principle applies: use a custom launcher script to include the widget JAR alongside the Phoebus product JAR.

Features

• Display interactive maps powered by Gluon Maps
• Add, remove, and configure markers dynamically
• Each marker can be linked to a Phoebus display (.bob file) for quick navigation

How It Works

The widget integrates the Gluon Maps library into the Phoebus display framework:

1. Map Rendering: Uses MapView from Gluon Maps to render map tiles and handle pan/zoom interactions.
2. Markers: Markers are stored as structured properties in the widget model (MapWidget.propCoords). Each marker contains:
   • Latitude and longitude
   • Display name
   • Path to a Phoebus display (.bob file)
   • Icon type (enum)
3. Tile Retrieval: By default, the widget uses a local tile server (LocalTileRetriever), but can be configured to use any tile source.
4. Interaction: Clicking a marker zooms to its location; double-clicking opens the associated display.
