Provided Data:

• MobileSensorReadings.csv - contains the sensor readings of different mobile sensor Ids over a period of time and its locations
• StaticSensorReadings.csv - contains the sensor readings of different static sensor Ids over a period of time
• StaticSensorLocations.csv - contains the different static sensor Ids with its locations

I will start with importing Static Sensor Data and then Mobile Sensor Data.

Combine static sensor data

Drag both StaticSensorReadings.csv and StaticSensorLocations.csv into the Tableau Data Source. A inner joined Data source is generated. 2 sets of data joined perfectly with common columns.

Create Static Sensor Map Graph

a. Drag Long and Lat into Columns and Rows respectively.

b. Go to the top right corner and click Show Me, select symbol maps
