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/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>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">

其中的jQuery-1.8.3.js的代码可以自己百度下,然后放到JS文件夹下面。
全部代码下载链接:下载链接
最后建议先用火狐浏览器打开这个baidumap,显示偏移的话可能是代码错了.google浏览器要改一下,需要配置google chrome支持本地(file协议)的AJAX请求:
设置浏览器的快捷方式属性,在“目标”后面加上--allow-文件访问从 - 文件,注意前面有个空格,重新打开浏览器即可。
如果还是不显示的话请用火狐浏览器。

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

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:

其中的jQuery-1.8.3.js的代码可以自己百度下,然后放到JS文件夹下面。全部代码下载链接:下载链接最后建议先用火狐浏览器打开这个baidumap,显示偏移的话可能是代码错了.google浏览器要改一下,需要配置google chrome支持本地(file协议)的AJAX请求:设置浏览器的快捷方式属性,在“目标”后面加上--allow-文件访问从 - 文件,注意前面有个空格,重新打开浏览器即可。如果还是不显示的话请用火狐浏览器。--------------------- 作者:新生GIS 来源:CSDN 原文:https://blog.csdn.net/qq_41046162/article/details/80248281 版权声明:本文为博主原创文章,转载请附上博文链接!
