什么是实时数据源？
我正在制作一个关于实时可视化的演示，并且我试图开箱即用。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）？

答案 0 :(得分：23)
只是一些想法：
环境数据集
正如其他评论所述，请查看weather，forecast（或类似服务）。
空间数据
What about data from the Universe?
航班
这里有一些real time flight tracking data：评估计划有限但是免费。
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），Foursquare
能源生产
Various energy production (real-time and quasi real-time) data。
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（对于您的注册网站）
货币
Bitcoin transactions，Stock Market API
更多？

您是否考虑过环境数据集？
首先，streamflow and water quality上有近实时（例如，每小时或15米）的数据。通过NOAA NCDC和API提供了大量的天气数据。一些bouy data怎么样？
看到this post提醒我，那里有很多航班跟踪数据，可视化也很有趣。
