Arcgis for js加载百度地图

通过学习了一段时间的arcgis for js，让我来讲一下如何在arcgis for js加载百度地图。

加载的结果显示：

                                                                           地图

                                                                  影像 - 无标注

                                                                           影像 - 有标注

制作步骤：

首先，我是在学习了https://blog.csdn.net/gisshixisheng/article/details/44853709这篇文章，代码大多都是那里的，参数也都没错，但是复制过去还是打不开，这个之后我会讲的。

其次，就是_百度地图在柯林斯调用的有地图在切片，影像切片，以及道路等POI切片，我将之用TiledMapServiceLayer做了扩展，成了BDAnoLayer，BDVecLayer，BDimgLayer三个图层，其代码如下:(通俗的意思就是在html同目录的新建一个文件夹，然后建立三个JavaScript文件分别是BDAnoLayer，BDVecLayer，BDImgLayer）

BDAnoLayer.js

define(["dojo/_base/declare",
"esri/layers/TiledMapServiceLayer",
"esri/geometry/Extent",
"esri/SpatialReference",

return declare(TiledMapServiceLayer, {

this.spatialReference = new SpatialReference({ wkid: 102100 });
this.initialExtent = (this.fullExtent = new Extent(-20037508.3427892, -20037508.3427892, 20037508.3427892, 20037508.3427892, this.spatialReference));

}
});
});

从上面的getTileUrl 可以看到，三者返回的URL的地址是没有有区别的，在上述的URL有可能失效，为了得到最新的地址，学习了那篇文章，我做了如下工作：

1，先用百度地图JS API调用并显示百度地图，代码如下：

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">  
body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";}
</style>
<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=NkuwFBPlXG1uqPDsB9nK2nqpyLFF0SFV"></script>
<title>地图展示</title>
</head>
<body>
<div id="allmap"></div>
</body>
</html>
<script type="text/javascript">
// 百度地图API功能  
var map = new BMap.Map("allmap");    // 创建Map实例  
map.centerAndZoom(new BMap.Point(116.404, 39.915), 5);  // 初始化地图,设置中心点坐标和地图级别  
map.addControl(new BMap.MapTypeControl());   //添加地图类型控件  
map.setCurrentCity("北京");          // 设置地图显示的城市 此项是必须设置的  
map.enableScrollWheelZoom(true);     //开启鼠标滚轮缩放  
</script>

你的密钥需要更改为百度API的密钥，有需要的要申请。

2，然后用chrome打开这个html，F12调试--NetWork--左边找一张切片，右边切换至预览面板

                                                                BDVecLayer.js（地图网址）

                                                                                BDImgLayer.js（影像链接）

                                                                                   BDAnoLayer.js（poi网址）

只需要将最后面的数字替换掉就行了，20180505。

3.将上面的三个JS调用到地图主页。

代码如下：

<!DOCTYPE html>
<html>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
