Overview
One of St. Himark’s largest employers is the Always Safe nuclear power plant. The pride of the city, it produces power for St. Himark’s needs and exports the excess to the mainland providing a steady revenue stream. However, the plant was not compliant with international standards when it was constructed and is now aging. As part of its outreach to the broader community, Always Safe agreed to provide funding for a set of carefully calibrated professional radiation monitors at fixed locations throughout the city. Additionally, a group of citizen scientists led by the members of the Himark Science Society started an education initiative to build and deploy lower cost homemade sensors, which people can attach to their cars. The sensors upload data to the web by connecting through the user’s cell phone. The goal of the project was to engage the community and demonstrate that the nuclear plant’s operations were not significantly changing the region’s natural background levels of radiation.
When an earthquake strikes St. Himark, the nuclear power plant suffers damage resulting in a leak of radioactive contamination. Further, a coolant leak sprayed employees’ cars and contaminated them at varying levels. Now, the city’s government and emergency management officials are trying to understand if there is a risk to the public while also responding to other emerging crises related to the earthquake as well as satisfying the public’s concern over radiation.
Data
Data Files
| Name | Info |
|---|---|
| VAST 2019 - St. Himark - About Our City.docx | A document describing the scenario, as well as general information about St.Himark |
| MC2_datadescription.docx | A document that provides descriptions for data files provided for MC2 |
| MobileSensorReadings.csv | Contains readings from 50 mobile sensors that are attached to cars.
Data fields include: Timestamp, Sensor-id, Long, Lat, Value, Units, User-id. The timestamps are reported in 5 second intervals, though poor data connectivity can result in missing data. Each sensor has a unique identifier that is a number from 1 to 50. Location of the sensor is reported as longitude and latitude values (see map description below). The radiation measurement is provided in the Value field. Radiation is reported with units of counts per minute (cpm). Each measurement is independent and does not represent a summation over the previous minute. Some users have chosen to attach a user ID to their measurements while some others chose with a default name. |
| StaticSensorReadings.csv | Contains readings from a set of carefully calibrated professional radiation monitors at fixed locations throughout the city.
Data fields include: Timestamp, Sensor-id, Value, Units. |
| StaticSensorLocations.csv | Contains locations of the static sensors |

Data Preprocessing and Cleaning
Creation of POI.csv
In 'MC2_datadescription.docx', a list of coordinates pertaining to the hospitals and Always Safe Nuclear plant located in St Hilmark was given. These are possible point of interests that might be of interest, so I decided to create a data file to contain the information.
| Step | Info |
|---|---|
| 1. |
 Open up MC2_datadescription.docx and scroll to the bottom to find coordinate information |
| 2. |
 Input the information into excel to create a .csv file. The resulting file contains the following data columns: |
