什么是实时数据源？

Question

我正在开发一个关于实时可视化的演示,我正在尝试开箱即用.看起来任何大数据实时演示都在Twitter或流量数据上.是否有其他选项可以发布实时数据(免费)？

谢谢

Answer 1

只是一些想法:

环境数据集

正如其他的评论说,看看到天气,预测(或类似的服务).

空间数据

那么来自宇宙的数据呢？

机票

这是一些实时航班跟踪数据:评估计划有限但免费.

社交网络

Twitter Streaming API,Facebook RealTime Updates API(如果你已经在社交网络上发布了应用程序),Foursquare

能源生产

各种能源生产(实时和准实时)数据.
对于这些,你可能不得不在页面上乱窜,以跟踪数据的来源,抱歉.

网站流量

Google Analytics RealTime API(适用于您的注册网站)

钱

比特币交易,股票市场API

更多？

和这里和这里的其他实时API服务的"不那么更新"列表(一些免费的,有些则不是).

Answer 2

您是否考虑过环境数据集？

其中之一是关于流量和水质的近实时数据（例如每小时或15m）。还可以通过NOAA NCDC和API提供大量的天气数据。一些bouy数据呢？

看到这篇文章提醒我，那里有很多飞行跟踪数据，可视化也很有趣。

Answer 3

您可以在 www.hooksdata.io 上找到实时数据源。使用查询语言，您可以指定所需的数据，然后在您想要接收数据的位置添加 Webhook URL，或者随时提取数据。
