I introduced a new variable Alert Value to set unsafe cpm level and using a calculated field of Alert Level to only show those points which are above the Alert Value. From the improved visualization we can see that most of the radiation level which are above 100 are in the central, north and south-east of the town. This diagram can help to recognise area of radiation found above a certain threshold and allow the relevant authority to check on the actual radiation level on the ground. | I introduced a new variable Alert Value to set unsafe cpm level and using a calculated field of Alert Level to only show those points which are above the Alert Value.

+ | With the addition of the scatter plot of the mobile sensor readings mapped by its respective neighbourhood along the time frame, we can see certain areas and time which has an increase in radiation level. We can identify some of the pocket of high recorded readings such as Old Town around the start of April 9 and Wilson Forest around the start of April 10 (which is the central and south-east of the city). <br> | ||
+ | From both the static and mobile sensor readings, we can also definitely see an increase in radiation level after April 8 (shown by the blue line on the graphs) which could be the cause of the earthquake which may have affected the nuclear power plant to suffer damage and causing an increase in radiation level throughout the city. |

1. Visualize radiation measurements over time from both static and mobile sensors to identify areas where radiation over background is detected. Characterize changes over time.
