@deck.gl/layers
Advanced tools
@deck.gl/layers is a versatile library for creating and rendering complex visualizations on top of maps using WebGL. It provides a variety of pre-built layers for different types of data visualization, including scatter plots, heatmaps, and 3D extrusions.
ScatterplotLayer
The ScatterplotLayer is used to render a collection of points, each with a specified position, size, and color. This is useful for visualizing data points on a map.
const scatterplotLayer = new ScatterplotLayer({
id: 'scatterplot-layer',
data: [
{position: [-122.45, 37.78], size: 100},
{position: [-122.46, 37.79], size: 200}
],
getPosition: d => d.position,
getRadius: d => d.size,
getColor: [255, 0, 0]
});HeatmapLayer
The HeatmapLayer is used to create a heatmap visualization, where the intensity of the heatmap is determined by the weight of each data point. This is useful for visualizing density or intensity of data points.
const heatmapLayer = new HeatmapLayer({
id: 'heatmap-layer',
data: [
{position: [-122.45, 37.78], weight: 1},
{position: [-122.46, 37.79], weight: 0.5}
],
getPosition: d => d.position,
getWeight: d => d.weight
});GeoJsonLayer
The GeoJsonLayer is used to render GeoJSON data, which can include points, lines, and polygons. This is useful for visualizing geographic features and boundaries.
const geoJsonLayer = new GeoJsonLayer({
id: 'geojson-layer',
data: 'https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/bart-stations.json',
pickable: true,
stroked: false,
filled: true,
extruded: true,
getFillColor: [160, 160, 180, 200],
getLineColor: [255, 255, 255],
getRadius: 100,
getLineWidth: 1,
getElevation: 30
});Leaflet is a popular open-source JavaScript library for interactive maps. It is lightweight and easy to use, but it does not offer the same level of WebGL-based performance and 3D visualization capabilities as @deck.gl/layers.
Mapbox GL JS is a powerful library for interactive, customizable vector maps rendered with WebGL. It offers high performance and a wide range of features, but it is more focused on map rendering and less on data visualization compared to @deck.gl/layers.
Three.js is a JavaScript library for creating 3D graphics in the browser using WebGL. While it provides a lot of flexibility and power for 3D rendering, it requires more effort to set up and use for map-based visualizations compared to @deck.gl/layers.
