openlayers在线地图:高德地图、天地图、谷歌、geoq(智图)

—————–2019年修订

天地图服务接口调用需要申请开发许可(Key)自己去官网注册),添加到请求地址后即可

对,没有百度地图,百度地图单独再说。

将获取的瓦片通过继承ol.source.XYZ来实现。

首先献上各地图获取地址:(顺便安利一下arcgis api 在线地图的实现

var mapUrl = {

继承xyz:

 

ol.source.onlineMap = function (options) {
    var options = options ? options : {};

    var attributions;//右下角标识
    if (options.attributions !== undefined) {
        attributions = option.attributions;
    } else if (options.mapType.indexOf("aMap") != -1) {
        attributions = new ol.Attribution({
            html: '&copy; <a class="ol-attribution-amap" ' + 'href="http://ditu.amap.com/">' + '高德地图</a>'
        });
    } else if (options.mapType.indexOf("tian") != -1) {
        attributions = new ol.Attribution({
            html: '&copy; <a class="ol-attribution-tianmap" ' + 'href="http://www.tianditu.cn/">' + '天地图</a>'
        });
    } else if (options.mapType.indexOf("geoq") != -1) {
        attributions = new ol.Attribution({
            html: '&copy; <a class="ol-attribution-geoqmap" ' + 'href="http://www.geoq.net/basemap.html">' + '智图地图</a>'
        });
    } else if (options.mapType.indexOf("google") != -1) {
        attributions = new ol.Attribution({
            html: '&copy; <a class="ol-attribution-googlemap" ' + 'href="http://www.google.cn/maps">' + '谷歌地图</a>'
        });
    }
    var url = mapUrl[options.mapType];
    ol.source.XYZ.call(this, {
        crossOrigin: 'anonymous',   //跨域
        cacheSize: options.cacheSize,
        projection: ol.proj.get('EPSG:3857'),
        url: url,
        attributions: attributions,
        wrapX: options.wrapX !== undefined ? options.wrapX : true
    });
};
ol.inherits(ol.source.onlineMap, ol.source.XYZ);//必需

食用方法:

以高德地图为例:

 var map = new ol.Map({
        layers: [
            new ol.layer.Tile({
                title: "高德影像地图",
                visible:false,
                source: new ol.source.onlineMap({mapType:"aMap-img"})
            }),
            new ol.layer.Tile({
                title: "高德矢量图",
                source: new ol.source.onlineMap({mapType:"aMap-vec"})
            }),
            new ol.layer.Tile({
                title: "高德路网地图",
                visible:false,
                source: new ol.source.onlineMap({mapType:"aMap-roadLabel"})
            })
        ],
        target: 'map',
        view: new ol.View({
            center:center,
            zoom: 4
        })
    });

 

一眼就看出来了各地图的风格不同:
