Kepler.gl demo

https://jw3.github.io/example-kepler.gl/

Uses Moving Features JSON (MF-JSON) from MobilityDB's libmeos as a datasource for the Kepler.gl Trip Layer

Demo

Deployed to GitHub Pages

1. Small json ~1000 tracks
2. Medium json ~3700 tracks
3. Large json ~9000 tracks

If no query param is specified the 1k dataset will load.

The simulation runs on the host machine's GPU with WebGL, the larger datasets may not like a smaller GPU.

The track color rendered in the demo is determined by the vessel type id.

Future

Kepler.gl has limited support for GeoArrow datasets. It would be interesting to compare performance against the geojson.

The limited support is for the Polygon Layer alone, so it would take some unknown amount of work to enable support for the Trip Layer used in this demo.
