添加标记方法1如果有多个点，可以生成多个特征（循环调用addFeature）consticonStyle=()=>newStyle({image:newIcon({scale:0.2,src:image})});constaddFeature=(point:Coordinate)=>newFeature({geometry:newPoint(Proj.fromLonLat(point)),properties,name:"currentlocation",population:4000,rainfall:500,});复制代码constpointSource=newVectorSource({features:[addFeature(point)],});constclusterSourceForLayer=newCluster({source:pointSource,distance:50,});constpointLayer=newVectorLayer({source:clusterSourceForLayer,zIndex:3,style:iconStyle,});map.addLayer(pointLayer);pointLayer.set("baseMap","iconLayer");方法二使用geojson渲染markconsticonStyle=()=>newStyle({image:newIcon({scale:0.2,src:image})});constpointSource=newVectorSource({features:newGeoJSON().readFeatures(geojson,{dataProjection:"EPSG:4326",featureProjection:"EPSG:3857",}),});constclusterSourceForLayer=newCluster({source:pointSource,distance:50,});constpointLayer=newVectorLayer({source:clusterSourceForLayer,zIndex:3,style:iconStyle,});map?.addLayer(pointLayer);pointLayer.set("baseMap","iconLayer");生成geojson格式geojson的方法：手动构建使用@turf/helpers，它提供了point、featureCollection等方法{"type":"FeatureCollection","features":[{"type":"Feature","properties":{"id":"customer002","name":"c2"},"geometry":{"type":"Point","coordinates":[119.777738303153,32.91324329434815]}},{"type":"Feature","properties":{"id":"customerId007","name":"张三"},"geometry":{"type":"Point","coordinates":[109.54393448864997,35.7427088696462]}}]}hovermarkpopoveroverlay需要一个dom元素，这里是consto=newOverlay({element:ref.current});map?.addOverlay(o);setOverlay(o);方法一是用select做的，它有一个select事件，它的事件参数有selected，如果不是空数组，说明你的鼠标悬停在标记上，可以弹出popover显示你要的内容想要constselect=newSelect({condition:pointerMove,hitTolerance:1,layers:[iconLayer],style:iconStyle,});select.on("select",(e)=>{const{selected}=e;if(selected.length){const[feature]=selected;const_feature=feature.get("features")[0];constid=_feature.get("id");constname=_feature.get("name");setContent({name,id});constcoordinate=feature.get("geometry").flatCoordinates;overlay.setPosition(坐标);}else{overlay.setPosition(undefined);}});map?.addInteraction(选择);第二种方法是用select来做，本质是通过pointerMove事件，所以可以直接在地图上监听pointerMove事件。具体的实现方法我没有试过。通过以上推断，我认为是可行的map.on("pointerMove",(e)=>{});clearmark通过useEffect(()=>{return()=>{//清除页面中的标记iconSource?.getFeatures().forEach((feature)=>{iconSource?.removeFeature(feature);});};},[points,iconSource]);addInteraction,addOverlay,addLayer方法的区别我一直没搞清楚它们的区别，目前我明白什么是：addLayer:是添加图层，图层分为：raster:Tile(图片)vector:Vector(geojson,lerc)vectorraster:VectorTile(pbf)addInteraction:addSelectandModifyaddOverlay:addOverlayandControlPopover可以用Overlay来做
