Map Overview¶
The Navigation page is the primary screen in Bristol Maps. It displays a full-screen map with real-time data overlays, navigation tools, and access to weather, tides, and more.
Screen Layout¶
Navigation Banner¶
The banner at the top of the screen displays real-time navigation data in a scrollable bar:
| Display | Description |
|---|---|
| Speed | Current speed over ground in knots |
| Depth | Water depth from NMEA depth sounder (when connected) |
| Boundary | Distance to the nearest loaded boundary line |
| Location | Current latitude and longitude coordinates |
| Compass | Current heading/bearing |
| Temperature | Water temperature (when NMEA sensor connected) |
Tip
The navigation banner opacity can be adjusted in Settings to avoid obscuring the map.
