Method & limitations
Data. Use PUBLIC only when at least two eligible public stations are available; otherwise include device or DEMO readings and label their sources. PUBLIC must be within 2 hours; DEMO/EXTERNAL within 1 minute. At least two stations are required. DEMO is simulated.
Method. Illustrative weights: 60% temperature (24–34°C) + 40% humidity (40–100% RH), capped at 0–100. Average up to four stations within 1.5 km of route vertices; otherwise the two nearest. Hover over the station count to see the selected stations.
Limitations. Mapbox travel times are estimates. Check ferry schedules when a crossing is included. Not a validated comfort/health metric or cumulative journey exposure.
About this project
Project work includes scheduled HKO data collection, validation and PostgreSQL storage, an interactive Mapbox interface, Grafana history and VPS deployment. A REST endpoint supports external sensor uploads.
