世界机场代码(ICAO)[带经纬度]国际民间航空组织机场代码（ICAOcode，InternationalCivilAviationOrganizationAirportCode），亦称国际民航组织机场代码，是国际民航组织为世界上所有机场所订定的识别代码，由4个英文字母组成。
ICAO机场代码通常用于空中交通管理及飞行策划等。
ICAO机场代码与一般公众及旅行社所使用的IATA机场代码并不相同。
现在从某论坛的模拟飞行软件的地图更新中提取了此部分数据，简单检验了一下数据的准确性，还不错，都定位在机场，虽然没有定位到航站楼，但能够定位在跑道上也是不错的，只是像虹桥机场这样的基本上就只定位在了二号航站楼的跑道上了。
世界机场代码共10789笔，分为csv、gpx和kml三种格式，其中csv为原始数据，包含了名称、ICAO代码、经纬度和高度信息。
可能存在误差，仅供位置演示参考。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
