EditableGeoJsonLayer

EditableGeoJsonLayer is implemented as a deck.gl layer. It provides the ability to view and edit multiple types of geometry formatted as GeoJSON (an open standard format for geometry) including polygons, lines, and points.

import React from 'react';
import DeckGL from 'deck.gl';
import { EditableGeoJsonLayer } from 'nebula.gl';

const myFeatureCollection = {
  type: 'FeatureCollection',
  features: [
    /* insert features here */
  ]
};

class App extends React.Component {
  state = {
    mode: 'drawPolygon',
    selectedFeatureIndexes: [],
    data: myFeatureCollection
  };

  render() {
    const layer = new EditableGeoJsonLayer({
      id: 'geojson-layer',
      data: this.state.data,
      mode: this.state.mode,
      selectedFeatureIndexes: this.state.selectedFeatureIndexes,

      onEdit: ({ updatedData }) => {
        this.setState({
          data: updatedData,
        });
      }
    });

    return <DeckGL {...this.props.viewport} layers={[layer]} />;
  }
}
