title: Marker Layer
order: 3

MarkerLayer 不同于PointLayer图层
**技术差异**
- MarkerLayer地图元素采用Dom元素绘制
- PointLayer 通过WebGL绘制元素。
**功能差异**
- MarkerLayer 元素的自定义性比较强任何HTML+ CSS的组合都可可以绘制在地图上。
- PointLayer 自定义性比较弱,实现成本比较高,优势可以绘制大量的数据,性能比交互。
## 使用
```javascript
import { Marker, MarkerLayer} from '@antv/l7'
```
### 构造函数
```javascript
const markerLayer = new MarkerLayer(option);
// 调用 addMarker方法 将多个Marker添加到Layer
scene.addMarkerLayer(markerLayer);
```
#### option
- cluster 是部分聚合 ```boolean``` 默认 ```false```
- clusterOption 聚合配置
- cluster 是部分聚合
- element ```function```
后续会增加更多配置项目
### 方法
#### addMarker
参数
- marker ```Marker``` 需要添加的Marker
添加Marker
通过Marker对象实例化一个Marker
```javascript
const marker = new Marker().setLnglat(); // 添加进Marker必须设置经纬度才能添加
markerLayer.addMarker(marker);
```
#### removeMarker
从MarkerLayer 移除Marker
#### getMarkers
获取MarkerLayer中的所有Marker
#### clear
清除掉所有的Marker
####
### Scene
#### addMarkerLayer
添加MarkerLayer
```javascript
scene.addMarkerLayer(layer);
```
#### removeMarkerLayer
移除MarkerLayer
```javascript
scene.removeMarkerLayer(layer);
```
