Rain detector

Using data from HKO, develop (relatively) precise rain detection
Thomas K

Initial digging

Digging of the web version showed some good news / bad news.

https://maps.weather.gov.hk/ocf/index_e.html

Good news:

  • Prediction data easily located

Bad news:

  • Data are already processed in server, shown as a series of png.
    • Due to the nature of grid-like data, it might be still useful.
  • No location-based prediction data found in web. Seems to be exclusive to Android / iOS / Windows 10 UWP app version (and UWP version seems to be built completely with web tech?)
  • The calling JS is (a little?) hard to read

Nest step(s)

  • Find data calling method from website
  • Find location-based data calling method from mobile app
