[Live example](https://l7.antv.antgroup.com/en/examples/point/image/weather/)

[Resource index](/llms.txt)

Provide a DOM element with `id="container"`. The original example source follows.

## Source

```js
import { PointLayer, Scene } from '@antv/l7';
import { GaodeMap } from '@antv/l7-maps';

const scene = new Scene({
  id: 'map',
  map: new GaodeMap({
    style: 'dark',
    center: [120.5969, 29.7918],
    pitch: 35,
    zoom: 7,
    rotation: 4.183582,
  }),
});
scene.on('loaded', () => {
  scene.addImage(
    '00',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*kzTMQqS2QdUAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '01',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*jH1XRb7F7hMAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '02',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*YaKSTr3L5i8AAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '04',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*dmniQrDpCYwAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '11',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*YaKSTr3L5i8AAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '15',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*YNlXQYCIzroAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '07',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*DccRTI6ZRLoAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '16',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*iQKoS6I-rO8AAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '06',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*f-wyS7ad5p0AAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '08',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*lHhzQrOW4AQAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '17',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*9Q0QS4GdaYcAAAAAAAAAAABkARQnAQ',
  );
  scene.addImage(
    '05',
    'https://gw.alipayobjects.com/mdn/antv_site/afts/img/A*LyuVRowl6nAAAAAAAAAAAABkARQnAQ',
  );
  fetch('https://gw.alipayobjects.com/os/basement_prod/c6042c6b-45fd-4e2e-adf8-fdbf060441e8.json')
    .then((res) => res.json())
    .then((data) => {
      const imageLayer = new PointLayer()
        .source(data)
        .shape('w', function (w) {
          return w;
        })
        .size(15);
      scene.addLayer(imageLayer);
    });
});
```

## Runtime environment

Before evaluating the example, await this setup in a page containing #container. Supporting files follow below.

```js
await (await import("/src/demo/setup.ts")).default({ container: document.getElementById('container'), path: "/examples/point/image/demo/weather.js" });
```


## src/demo/setup.ts

```ts
import type { DemoSetupContext } from '@antv/astro-theme-antv';
import * as District from 'district-data';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';

export default async function setup({ container, path }: DemoSetupContext) {
  // Tool pages provide their own React layout and SDK imports.
  if (!path.startsWith('/examples/')) return;
  // Retain only the original globals still used by gallery examples.
  Object.assign(window, { District, GLTFLoader });
  const map = document.createElement('div');
  map.id = 'map';
  container.append(map);
  await import('./map.css');
  // Match the original gallery's shared AMap environment, including raw AMap demos.
  await import('./amap');
}
```

## src/demo/map.css

```css
#map {
  position: relative;
  width: 100%;
  height: 100%;
  min-height: 320px;
}

.labelclass {
  position: absolute;
  display: inline;
  cursor: pointer;
  background: rgb(255, 228, 120);
  border: solid 2px #fff;
  padding: 4px;
  white-space: nowrap;
  font:
    bold 12px/18px arial,
    sans-serif;
  color: #fff;
  border-radius: 50%;
  width: 40px;
  height: 40px;
  line-height: 30px;
  /* opacity: 0.7; */
  text-align: center;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
```

## src/demo/amap.ts

```ts
import AMapLoader from '@amap/amap-jsapi-loader';

// Preserve the site's development and production SDK registrations.
const credentials = import.meta.env.DEV
  ? { key: '6f025e700cbacbb0bb866712d20bb35c', securityJsCode: '290ddc4b0d33be7bc9b354bc6a4ca614' }
  : { key: 'f59bcf249433f8b05caaee19f349b3d7', securityJsCode: '2653011adeb04230b3a26cc9a780a800' };
window._AMapSecurityConfig = { securityJsCode: credentials.securityJsCode };
await AMapLoader.load({ key: credentials.key, version: '2.0', plugins: ['Map3D'] });
```
