【云图】自有数据的多边形检索(云检索)
摘要:记录每天的生活轨迹,分享美食心得,哪里有免费停车,制作班级通讯录等等,都可以用到云图。无论你是开发者,还是app用户,都可以用云图制作一张属于你的专属地图。
---------------------------------------------------------------------------------------------------------
一、通过坐标拾取工具得到经纬度:

(当然,如果你是开发者,你可以使用定位SDK,获取自己的经纬度,详见:http://api.amap.com/location/index )
二、建立自己的数据表
( 数据保存为CSV格式哟)

将数据导入云图:
http://yuntu.amap.com/datamanager/index.html
当然,如果你没那么多记录,一次不能导入那么多数据的话。你可以每天记录一点点哟!
点击右上角的按钮,可以手工输入一个点哦!
三、建立索引(这步灰常重要!很多开发者因为没建立索引,而导致无法检索到自己数据哦)
文本索引
塞选排序索引
四、好啦,要开始写代码啦。
不用担心,我都写好在这里了,你直接copy去用吧。
当然更多复杂功能,你可以看看官网的开发指南啊,类参考啊,示例啊。http://api.amap.com/yuntu/guide
(如果你是移动端的开发者,可以使用REST API,就是webservice服务,来获取json数据,并展示在自己的应用上。)
显示云图层:
var mapObj; //初始化地图对象,加载地图 function mapInit(){ mapObj = new AMap.Map("iMap",{center:new AMap.LngLat(116.39946,39.907629),level:10}); addCloudLayer(); //用于展示麻点图 } //叠加云数据图层 function addCloudLayer() { //清除地图上数据 mapObj.clearMap(); //加载云图层插件 mapObj.plugin('AMap.CloudDataLayer', function () { var layerOptions = { query:{keywords: ''}, clickable:true }; cloudDataLayer = new AMap.CloudDataLayer('533ccc56e4b08ebff7d539eb', layerOptions); //实例化云图层类 cloudDataLayer.setMap(mapObj); //叠加云图层到地图 AMap.event.addListener(cloudDataLayer, 'click', function (result) { var clouddata = result.data; var infoWindow = new AMap.InfoWindow({ content:"<h3>"+ clouddata._name + "</h3>" + "<p>分类:" + clouddata.tag + "</p><p>一句话:"+ clouddata.content +"</p>", size:new AMap.Size(300, 0), autoMove:true, offset:new AMap.Pixel(0,-5) }); infoWindow.open(mapObj, clouddata._location); }); AMap.event.addListener(mapObj,"click",function(){ mapObj.clearInfoWindow(); }); }); }
清除图层
//清除图层 function clearMap(){ cloudDataLayer.setMap(null); }
这次清除图层之后,要再次显示图层,需要重新建立地图对应关系。
cloudDataLayer.setMap(mapObj);
通过索引渲染图层,实时渲染的哦
//索引检索 function getType(tag){ cloudDataLayer.setMap(mapObj); var op={ query:{keywords:tag} } cloudDataLayer.setOptions(op); }
