Map layers: switches for overlays, a tick for the chosen base map
User Guide › Map layers
Map layers
Layers add information underneath the live objects: weather, day and night, nautical marks, airspace - and choose the map itself.
Opening layers
Open the menu and choose Map layers. Overlays have a switch and can be combined; base maps are a list where the ticked one is in use. Your choices are remembered on this device and included in shared links.
Environment
| Layer | What it shows |
|---|---|
| Wind | Animated particles drifting with the current wind 10 m above the ground, from Open-Meteo. Refreshed when you move the map and every 15 minutes. |
| OpenSeaMap | Nautical marks from OpenSeaMap: buoys, beacons, lights and harbour details. Most useful zoomed in on the coast. |
| Day / night | Shades the side of the Earth that is in darkness. The shade deepens gradually from sunset through dusk (twilight) to full night, and moves with the sun every minute. |
| Precipitation | The latest rain and snow radar from RainViewer. |
Base maps
Under Map, choose the map underneath everything: OpenFreeMap styles (Bright, Liberty, Positron, Dark, Fiord), OpenStreetMap, CARTO, ESRI satellite and streets, and others. Only one can be in use at a time. To make the map quieter, turn on Dim Map in Settings.
Overlays
Further groups add aviation overlays where they are available: airspace (openAIP), US flight restrictions, special-use airspace and weather radar, and European items such as radar corridors, AWACS orbits and air-to-air refuelling areas. Switch on any combination.
Drawing order
Layers always stack in the same order, so nothing important is hidden. From the top: labels, satellites, aircraft and vessels, the "What's nearby" circle, tracks, your position and range rings, airspace overlays, wind, precipitation, the satellite footprint, day / night, OpenSeaMap, and finally the base map.
