Fp64Extension

The Fp64Extension adds 64-bit precision to geospatial layers.

Note: This extension is the equivalent of the fp64 prop from older deck.gl versions. As of v6.3, the fp64 mode was deprecated in favor of the new default 32-bit projection mode that is comparable in precision but considerably more performant.

import {GeoJsonLayer} from '@deck.gl/layers';
import {Fp64Extension} from '@deck.gl/extensions';

const layer = new GeoJsonLayer({
  id: 'geojson-layer',
  data: GEOJSON,
  ...
  extensions: [new Fp64Extension()]
});
