Just saw a great presentation yesterday at EPA's Region 2 Citizen Science Forum by Amy Gottsegen of Drexel University (Gwen Ottinger's student) on http://shenangochannel.org/. CMU's CREATE Lab is also involved but i'm not sure how the project is structured.
- There's a timelapse video which you can browse by calendar as well as timeline, and there's additional controls like zooming in and out.
- scrolling the video's timeline also controls the position and zoom level shown in graphs of air quality sensors, in this case, they have a few Specks installed.
It is open source: https://github.com/CMU-CREATE-Lab/the-shenango-channel
They've made a tour of their dashboard that is super helpful:
