A button that switches the map between the flat mercator projection and a globe.
<HoloMap.Control.Globe position="top-right" />New in MapLibre GL JS 6. The projection is a rendering choice, not data: the same sources and layers draw either way, and nothing in your components needs to know which is active.
Props
| Prop | Type | Notes |
|---|---|---|
position | string | Corner to place the control in. Default "top-right" |
The control takes no options of its own, because MapLibre's GlobeControl
constructor accepts none.
When a globe helps
At low zoom the mercator projection inflates everything far from the equator, which is the wrong story for anything global: coverage maps, flight paths, climate data. A globe removes that distortion and makes polar regions readable. Past roughly zoom 6 the two are indistinguishable, so the control earns its place on world views and clutters a city map.
Pair it with HoloMap.Control.Navigation. A rotated globe is much easier to
reset with a compass than by dragging.
