[转载]【高德地图API】如何用云图记录生活(旅游app,美食记录,免费停车,通讯录都适用) – 酸奶小妹 – 博客园.
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)
tag,name,lng,lat,tel,content 免费停车场,免费停车场001,116.430359,39.958175,010-52294832,停过5次没贴条 免费停车场,免费停车场002,116.279297,40.00132,010-52294832,停过1次没贴条 免费停车场,免费停车场003,116.202393,39.825413,010-52294832,停过2次没贴条 免费停车场,免费停车场004,116.564941,39.835959,010-52294832,停过7次没贴条 免费停车场,免费停车场005,116.437225,39.806426,010-52294832,停过20次没贴条 通讯录,酸奶小妹,116.441345,39.961333,18393727348,喝酸奶补钙 通讯录,吴蔚,116.374054,39.957122,15000038375,蹦跶的幽默感 通讯录,王倩,116.233978,39.943436,1348377294,房姐白富美 通讯录,张小颖,116.353455,39.929748,1869393933,精明俏主妇 美食记录,望京总店马兰拉面,116.183167,40.022356,010-39382872,嘴巴起泡都要吃!西安辣椒爽到翻! 美食记录,绿茶,116.411133,39.992904,010-39382872,就是便宜啊,麻婆豆腐才8元。港丽你敢这么卖麽? 美食记录,西贝莜面村,116.507263,39.855992,010-39382872,猜拳赢了115元!老板叫了11个黄馍馍,11个莜面! 美食记录,酷圣石,116.133728,39.880235,010-39382872,K总最爱的酷石头,全北京最好吃冰淇淋。其实量太大,吃不完就化掉了。 美食记录,吉野家,116.336975,39.886558,010-39382872,有学生卡啊,就去买啊。 美食记录,鹿港小镇,116.383667,39.916056,010-39382872,海南鸡饭比三亚的还好吃!爱,赞! 美食记录,星巴克,116.523743,40.008683,010-39382872,如果不是傻2的买了2张98的会员卡,你以为我会去消费麽! 旅行记录,天安门,116.483917,39.91395,010-283764648,我爱北京天安门 旅行记录,红螺寺,116.419373,39.941331,010-283764648,爬山,没看到寺庙 旅行记录,大觉寺,116.411133,39.889719,010-283764648,玉兰花美,银杏树大 旅行记录,鸟巢,116.27655,39.838068,010-283764648,住的地方,空气好点 旅行记录,大兴西瓜村,116.433105,39.785323,010-283764648,西瓜贵死人
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。)
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> " + " 分类:" + clouddata.tag + " 一句话:"+ clouddata.content +" ", 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); }

注册你自己的key,填在源代码里哦:http://api.amap.com/key/index
