（转） Arcgis for js加载百度地图

http://blog.csdn.net/gisshixisheng/article/details/44853709

概述：

在前面的文章里提到了Arcgis for js加载天地图，在本节，继续讲解如何在Arcgis for js中加载百度地图。

效果：

地图

影像-无标注

影像-有标注

实现：

第一，在此感谢http://www.cnblogs.com/chenyuming507950417/p/3343729.html这篇文章的主人，给了我很大的启发与帮助，因为一直在找相关的参数，都不对，只有这个参数是没有问题的。

第二，百度地图可调用的有地图切片，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：

BDAnoLayer.js

1. define(["dojo/_base/declare",

43. ]
44. });
45. this.loaded = true;
46. this.onLoad(this);
47. },
48. getTileUrl: function (level, row, col) {
49. var zoom = level - 1;
50. var offsetX = parseInt(Math.pow(2, zoom));

55. }
56. });
57. });

从上面的getTileUrl可以看到，三者返回的url的地址是有区别的，在上述那边博文里面提到的url已经失效，为了得到最新的地址，我做了如下工作：

1、用百度地图JS API调用并显示百度地图，代码如下：

1. <!DOCTYPE html>
2. <html>
3. <head>
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5. <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
6. <style type="text/css">
7. body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";}
8. </style>
9. <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的秘钥"></script>
10. <title>地图展示</title>
11. </head>
12. <body>
13. <div id="allmap"></div>
14. </body>
15. </html>
16. <script type="text/javascript">
17. // 百度地图API功能
18. var map = new BMap.Map("allmap");    // 创建Map实例
19. 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
20. map.addControl(new BMap.MapTypeControl());   //添加地图类型控件
21. map.setCurrentCity("北京");          // 设置地图显示的城市 此项是必须设置的
22. map.enableScrollWheelZoom(true);     //开启鼠标滚轮缩放
23. </script>

2、F12打开Chrom调试——NetWork——左边找一张切片，右边切换至Preview面板

地图url

影像url

poi url

如此，URL即为切片的Url，其中online后面的数字2即为代码中的num，x为代码中的numX，y为numY，z为缩放级别。

第三，调用显示
调用显示比较简单，代码如下：

1. <!DOCTYPE html>
2. <html>
3. <head>
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
5. <title>Baidu Map</title>
