Introduction

Data Preparation

Insight & Conclusion

 


Meteorological data

As Meteorological data only contains the information for every three hours while Sensor data provides data for every hour. I estimated wind direction and wind speed as following.

Step 1:

Create Date1 and Date2 which are one and two hours after Date respectively.

Step 2:

Stack Date, Date1 and Date2 to one column.

Step 3:

Estimate the direction and speed by the following formula.

The dataset prepared for analyzation would look like as following.

Factory Responsibility

To see the influence area of each factory due to the wind, I did data preparation as following.

Assume the default angle of influence area is 30 degree. Set 12 points for each fan-shape.

The dataset prepared for analyzation would look like as following.
