MapLibre GL JS is a powerful open-source library that uses WebGL to render interactive maps from vector tiles in a browser. deck.gl's MapView
can sync perfectly with the camera of MapLibre, at every zoom level and rotation angle.
Integration Modes
When using deck.gl and MapLibre, there are three options you can choose from: interleaved, overlaid, and reverse-controlled.
Interleaved
The interleaved mode renders deck.gl layers into the WebGL2 context created by MapLibre. If you need to mix deck.gl layers with MapLibre layers, e.g. having deck.gl surfaces below text labels, or objects occluding each other correctly in 3D, then you have to use this option.
Interleaving is supported by using MapboxOverlay with interleaved: true
. It requires WebGL2 and therefore only works with maplibre-gl@>3
. See compatibility and limitations.
Overlaid
The overlaid mode renders deck.gl in a separate canvas inside the MapLibre's controls container. If your use case does not require interleaving, but you still want to use certain features of maplibre-gl, such as maplibre-gl controls (e.g. NavigationControl
, Popup
) or plugins (e.g. navigation directions, mapbox-gl-draw), then you should use this option.
This is supported by using MapboxOverlay with interleaved: false
.
Reverse Controlled
The reverse-controlled mode renders deck.gl above the MapLibre container and blocks any interaction to the base map. If your use case does not require interleaving, but you need to implement your own pointer input handling, have multiple maps or a map that does not fill the whole canvas (with Deck's multi-view feature), you need this to allow deck.gl manage the map's size and camera.
You cannot use maplibre-gl controls and plugins with this option. Instead, use the components from @deck.gl/widgets
.
Examples
Example: interleaved or overlaid
Both the interleaved and the overlaid options are supported by the @deck.gl/mapbox module. This is recommended approach for developers coming from the MapLibre ecosystem, as it can easily switch between interleaved and overlaid rendering, as well as being compatible with other MapLibre controls and plugins.
- TypeScript

import {MapboxOverlay} from '@deck.gl/mapbox';
import {ScatterplotLayer} from '@deck.gl/layers';
import {Map} from 'maplibre-gl';
import 'maplibre-gl/dist/maplibre-gl.css';
const map = new Map({
container: 'map',
style: 'https://basemaps.cartocdn.com/gl/positron-gl-style/style.json',
center: [0.45, 51.47],
zoom: 11
});
await map.once('load');
const deckOverlay = new MapboxOverlay({
interleaved: true,
layers: [
new ScatterplotLayer({
id: 'deckgl-circle',
data: [
{position: [0.45, 51.47]}
],
getPosition: d => d.position,
getFillColor: [255, 0, 0, 100],
getRadius: 1000,
beforeId: 'watername_ocean' // In interleaved mode render the layer under map labels
})
]
});
map.addControl(deckOverlay);
import React from 'react';
import {Map, useControl} from 'react-map-gl/maplibre';
import {MapboxOverlay} from '@deck.gl/mapbox';
import {DeckProps} from '@deck.gl/core';
import {ScatterplotLayer} from '@deck.gl/layers';
import 'maplibre-gl/dist/maplibre-gl.css';
function DeckGLOverlay(props: DeckProps) {
const overlay = useControl<MapboxOverlay>(() => new MapboxOverlay(props));
overlay.setProps(props);
return null;
}
function App() {
const layers = [
new ScatterplotLayer({
id: 'deckgl-circle',
data: [
{position: [0.45, 51.47]}
],
getPosition: d => d.position,
getFillColor: [255, 0, 0, 100],
getRadius: 1000,
beforeId: 'watername_ocean' // In interleaved mode render the layer under map labels
})
];
return (
<Map
initialViewState={{
longitude: 0.45,
latitude: 51.47,
zoom: 11
}}
mapStyle="https://basemaps.cartocdn.com/gl/positron-gl-style/style.json"
>
<DeckGLOverlay layers={layers} interleaved />
</Map>
);
}
You can find full project setups in the react get-started example and pure js get-started example.
Example: reverse controlled
The reverse-controlled option is supported by the pre-built scripting bundle, and in React when used with the react-map-gl
library. There is currently no easy way to do it under Vanilla JS.

Additional Information
react-map-gl
react-map-gl is a React wrapper around maplibre-gl maintained by the vis.gl community. If you'd like to use deck.gl together with maplibre-gl and React, this library is the recommended companion.
All the examples on this website are implemented using the React integration.
When you choose the interleaved or overlaid option, the react-map-gl Map React component acts as the root component, and MapboxOverlay is used with react-map-gl's useControl
hook.
When you choose the reverse-controlled option, the DeckGL
React component acts as the root component, and the react-map-gl Map is a child. In this case, Map
will automatically interpret the deck.gl view state (i.e. latitude, longitude, zoom etc), so that deck.gl layers will render as a synchronized geospatial overlay over the underlying map.
Choosing a map tile service
There are paid map tile servers such as MapTiler, Stadia Maps, and AWS Location Service.
deck.gl public demos use CARTO free basemaps as a non-commercial application. Checkout this guide to start using it.
If you host your own map tiles, you will need a custom map style JSON that points to your own vector tile source, this custom style must match the schema of your tile source.
Open source tile schemas include:
Some useful resources for hosting your own map tiles:
- Martin, a tile server from the MapLibre organization
- Open source tools
- Maputnik Style editor
