  • （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

    51.                 var offsetY = offsetX - 1;  
    52.                 var numX = col - offsetX, numY = (-row) + offsetY ;  
    53.                 var num = (col + row) % 8 + 1;  
    54.                 return "http://shangetu" + num + ".map.bdimg.com/it/u=x="+numX+";y="+numY+";z="+level+";v=009;type=sate&fm=46&udt=20141015";  
    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：

    [html] view plain copy
     
     print?
    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 { 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：

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