首先,在初始化地图时,创建一个新的VectorLayer对象,并将其添加到地图上。这个新图层将用于高亮显示选中的道路。例如: this.highlightLayer = new VectorLayer({ zIndex: 9999, source: new VectorSource({ features: [] }), style: new Style({ stroke: new Stroke({ color: '#ff0000', width: 5 }) ...
import {Map, View, Feature, Overlay} from "ol"; // 比绘制底图多引入了一个Overlay import "ol/ol.css"; import VectorLayer from "ol/layer/Vector"; import XYZ from "ol/source/XYZ"; import {Tile as TileLayer} from 'ol/layer.js' import VectorSource from 'ol/source/Vector.js' 1. 2. ...
2. 在地图上添加图层以显示打点 接下来,我们需要添加一个图层来显示我们的点。通常使用矢量图层(ol/layer/Vector)来显示点: javascript var vectorSource = new ol.source.Vector(); var vectorLayer = new ol.layer.Vector({ source: vectorSource }); var map = new ol.Map({ target: 'map', layers: ...
(startMarker);varvectorLayer=newol.layer.Vector({source:vectorSource,style:newol.style.Style({image:newol.style.Icon({anchor:[0.5,1],src:'https://openlayers.org/en/v4.6.5/examples/data/icon.png'})})});map.addOverlay(vectorLayer);varelement=document.getElementById('popup1');varpopup=...
组件引入openlayer import*asolfrom'../openLayer' openLayer.js 内容如下: export{Map,View,Feature}from'ol'export{TileasTileLayer,VectorasVectorLayer}from'ol/layer'export{Select}from'ol/interaction'export{Point}from'ol/geom'export{XYZ,VectorasVectorSource,ImageStatic,ImageWMS,Cluster}from'ol/source...
