Draw a UML Diagram for this

An agency has to follow air quality control.

The set of sensors is described in another file, having one sensor per line, under the following format:

 SensorID;Latitude:Longitude;Description; 

The different types of measures are in a third file:

 AttributeID;Unit;Description; 

An agency requires a software application to follow the sensors state and to get aggregate information. Aggregate information will help deciders to take decisions to enhance air quality. For example, on a given territory, get the mean air quality at a given time, or on a given timespan. It is also required to identify sensors with similar behaviours.
