1、引入openlayer的api
<link rel="stylesheet" href="../lib/openlayerv6.4.3/css/ol.css">
<script src="../lib/openlayerv6.4.3/build/ol.js"></script>
2、创建地图图层
var rootLayer = new ol.layer.Tile({
source: new ol.source.XYZ({
url: 'http://mt2.google.cn/vt/lyrs=y&hl=zh-CN&gl=CN&src=app&x={x}&y={y}&z={z}&s=G'
}) //加载谷歌影像地图
});
3、创建view
var view = new ol.View({
center: [113, 23],//设置地图默认中心点
projection: 'EPSG:4326',//坐标系
zoom: 10//默认缩放级别
});
4、创建map
map = new ol.Map({
layers: [rootLayer],//加载创建的地图图层
target: 'map',//地图的显示容器
view: view
});
效果图:
