FAQ

What is the Fresh Hikes Finder?
The Fresh Hikes Finder wants to help people maximize the benefits of hiking by choosing routes with the best air quality. It combines government data on various districts' air quality (AQHI and AQI) and weather with hiking route data in order to recommend the 'freshest' hikes for any given day or hour. It is in its current state a web prototype, but The Fresh Hikes Finder will eventually take the form of a mobile app.
That big number on the bottom left of the hike cards - what does it mean and how is it calculated?
That's the Freshness Factor - it is a combination of data from the Air Quality Health Index (AQHI) and the Air Quality Index (AQI), turned into a percentage and inverted so that the higher the number, the better. This number is updated on an hourly basis over 15 air quality measuring stations. If a hike spans more than one district or measuring station, a weighted average is taken.
The different colours of the hike cards - what do they mean?
These colours indicate the Health Risk Levels, as defined and colour coded by the Air Quality Health Index (www.aqhi.gov.hk):
1 - Low
2 - Low
3 - Low
4 - Moderate
5 - Moderate
6 - Moderate
7 - High
8 - Very high
9 - Very high
10 - Very high
11 - Serious
