Getting the CHMI data from the Golemio API

cd data-chmi
./get
./merge

Plotting the CHMI data as function of space and time

You can choose the number of the pollutant from the following: SCALE is 0 to 100. Numbers beyond 100 are projected to 100.

1. "NO2": Video
2. "O3" : Video
3. "PM10"
4. "PM10_24"
5. "PM2_5"
6. "SO2"

cd data-chmi
python plotPollutionMaps.py
./buildVideo.sh

Difficulty are:

• Data were unknown before starting.
• Data are heterogeneous in space, very discontinuous in time, and sometimes just missing.
• Management of timestamps and data types of Python.
