Map Window

The Map Window provides an interactive interface for viewing and managing platforms on a map. The platform position and relevant sensor details are extracted from MISB metadata embedded in the video streams.

To display this information, press the Stream Detection button.

Controls

  • Mode Selection: Choose between different modes for platform or map movement. This allows you to either move the map itself or interact with platforms displayed on the map.
  • Zoom In/Out: Use the zoom controls to adjust the map's scale, allowing you to view a larger area or focus on specific details.
  • Full Screen: Toggle full screen mode to maximize the map window for better visibility and interaction.
  • Ruler (Distance Measurement): Activate the ruler tool to measure distances between points on the map. Click to set start and end points, and the measured distance will be displayed.

⚠️ Internet Connection Requirement

The map requires an active Internet connection to load map tiles. Without Internet access, the map may not display correctly or may be unavailable.
Alternatively, you can enable offline mode using pre-loaded maps. When offline maps are available, the application will display locally stored tiles instead of downloading them from the Internet.

Klv Metadata overlay

The map overlay reads these tags:
- 5 (Platform Heading Angle): rotates the platform icon and is used in Field of View (FOV) cone direction.
- 13 (Sensor Latitude): updates platform position and FOV cone origin latitude.
- 14 (Sensor Longitude): updates platform position and FOV cone origin longitude.
- 16 (Sensor Horizontal Field of View): sets the FOV cone fan angle.
- 18 (Sensor Relative Azimuth Angle): combined with tag 5 to compute FOV cone direction.
- 23/24 (Frame Center Latitude/Longitude): draws the frame-center marker/line and can be used to derive FOV cone radius.
- 26-33 (Offset Corner Latitude/Longitude): builds a footprint polygon from offsets relative to tags 23/24.
- 82-89 (Corner Latitude/Longitude): builds a footprint polygon from absolute corner coordinates.
