Reported Deaths Map Analysis: View Reported Deaths Map
The plotted points are gathered information based on the cholera deaths within the University of Oregon. The information gathered allowed me to analyze and find out the areas suppressed with most deaths. Over a 9 day span, the amount of deaths fluctuated every day which help to distinguish where the probable source of the outbreak was. Using resources such as the Facebook and Twitter maps, the speculations could be made much clearer and with more elasticity to my speculation. The 150 foot buffer was created to find the overlapping areas in which deaths occurred. The 150 foot range was established in order to contain the buffer inside the University of Oregon campus area. The density map also helped me to find the most dense areas for deaths.
The source of the outbreak was distinguished to be on the southern section of Frohnmayer Music and Dance building in the Aasen-Hull Hall.

By mapping the activities of the cholera-infected people, I have determined that the source of the cholera epidemic is located in the Aasen-Hull hall, which is located in the southern section of the Frohnmayer Music and dance building.
When I was creating this thematic map, I recorded at the behaviors, activities, and paths that cholera-infected people took. First, I created points features which represent places where people were last seen, where their bodies were found, and places that they visited while or right before they became sick. Then, I used line features to create pathways that the infected normally would have taken which serves to highlight how the illness spread.This is shown through lines that connect certain spots together. When point features or line features ended up at an area such as a building, dorm, or an area, I created area objects which capture that space and highlight it.
I first became suspicious that the outbreak’s source was located in the Frohnmayer music building by the fact that the highest density of occurrences (places where people were seen or where they traveled) happens to be located on the northwestern part of the building and the area in between the Frohnmayer Music Building and the Knight Library. Next, I distinguished certain lines and points from one another by color coding them according to which day the event occurred. This allowed me to follow the trail of events back to the first day of the outbreak.
I created a trail by looking at events that happened on the first day, which is color-coded as black. I saw that the infected were active around the clinical services building and Aasen-hull hall. On day two, which is represented as red, there were events in the clinical services building, and the Hedco education building. Then, on day three, which is represented as green, there were events happening in multiple buildings including the Knight library,the rec center, Walton hall, and the Lokey Education buildings.It is possible to deduct that if person A happens to be active in a building that an infected person had visited or come in contact with, there is the possibility that person A will infect person B,C,D and so on. Line features became very important in this part because it allowed me to visualize the paths that people were taking. Additionally, with the line features ultimately let me follow people’s paths back to Aasen-hull hall.
With knowledge I had from the Facebook information, I looked at the distribution of reported deaths that nick had gathered from the white flags and saw that there was a clustering of points around the Frohnmayer Music Building while other points across the map happened to be less dense and more distributed and randomized. Additionally, I looked at the distribution of tweets and saw that there was also a high density of tweets coming from Aasen-Hull Hall while the locations for other tweets tended to be less clustered and more randomized. Assuming that tweets were supposed to be coming from other students, the subject of some of the tweets centered around the disturbances in the music building, where Aasen-Hull hall is located. For example, one tweet coming from the Lokey Education complex said, “does anyone know why MUS 394 and MUS 327 are cancelled?”
By looking at the densities of locations of deaths from cholera, tweets about the outbreak, the paths and points that the sick took and visited, I am able to say that the source of the cholera outbreak is in Aasen-Hull Hall.

Information gathered from specific points such as Tweet 28, “So sad.. Just last week I talked to the janitor that passed away.” are one of the many tweets that lead to our discovery of the source location. Typically a janitor only has one building that he is responsible for, so the fact that the only reported death of a janitor was of the one who worked in the Frohnmayer Music Building is a good start. Another contributing factor that leads me to think the source is in the Frohnmayer Music Building is that many music students tweeted about cancelled classes in this building. Furthermore, if we look at both the buffer and density maps created out of the tweets we can see the color is darkest at the Frohnmayer Music Building. Leading to my conclusion that the source of the cholera outbreak started in the Frohnmayer Music Building.
Group Analysis
After performing our individual analysis we came together and looked at the posts on Twitter and Facebook along with corresponding deaths locations of individuals, which lead us to our conclusion. We expect that the source of the Cholera Outbreak was located at the School of Music and Dance which is the southern part of the Frohnmayer Music Building.
