如何在 ngx-leaflet 中放置热图？

Question

我想在 ngx-leaflet 地图上放置一个热图（使用 angular），如下图所示。

我怎样才能做到这一点？

这里是例子的demo。

Answer 1

安装传单，ngx-传单，@types/leaflet

npm install leaflet
npm install leaflet.heat
npm install @asymmetrik/ngx-leaflet
npm install --save-dev @types/leaflet

在 angular.json

中导入 leaflet.css

  "styles": ["../node_modules/leaflet/dist/leaflet.css", "styles.css"]

安装Leaflet.heat并在comp.ts上导入，从assets

导入要使用的地理数据

import 'leaflet.heat/dist/leaflet-heat.js'
import { addressPoints } from '../assets/realworld.10000'

监听 onMapReady 事件获取对地图的引用并将热图添加到地图

onMapReady(map) {
    let newAddressPoints = addressPoints.map(function (p) { return [p[0], p[1]]; });
    const heat = L.heatLayer(newAddressPoints).addTo(map);
}
