I would like to put a heatmap over a ngx-leaflet map (using angular), like in the following image.
How can I achieve that?
Here is the demo of the example.
Install leaflet, ngx-leaflet, @types/leaflet
npm install leaflet
npm install leaflet.heat
npm install @asymmetrik/ngx-leaflet
npm install --save-dev @types/leaflet
Import leaflet.css in angular.json
"styles": ["../node_modules/leaflet/dist/leaflet.css", "styles.css"]
Install Leaflet.heat & import it on comp.ts, import the geographic data to be used from assets
import 'leaflet.heat/dist/leaflet-heat.js'
import { addressPoints } from '../assets/realworld.10000'
Listen to onMapReady event get the reference to the map & add heatmap to the map
onMapReady(map) {
let newAddressPoints = addressPoints.map(function (p) { return [p[0], p[1]]; });
const heat = L.heatLayer(newAddressPoints).addTo(map);
}
