Google Maps and deck.gl ArcLayer

  • This example visualizes curved connections between Prague and major airports worldwide using theArcLayer from deck.gl.

  • TheArcLayer is rendered on top of a Google Map, displaying flight paths originating from Prague.

  • The code utilizes GeoJSON data of airports and filters them based on a scalerank property for visualization.

  • You can interact with a live version of this example on JSFiddle or clone the sample code for local execution.

Visualizing points with arcs

This example uses arcs to show curved point-to-point connections betweenairports and the city of Prague. TheArcLayer renders raised arcs joining pairs of source and target points.

Note: The JavaScript is compiled from the TypeScript snippet.
