Overview (Mini-Challenge 1)
In 2017, it was suggested that the Kasios Furniture manufacturing company may have been a primary contributor to the apparent reduction of the number of nesting pairs of the Rose-Crested Blue Pipit. Kasios supposedly used the banned substance Methylosmolene in their manufacturing process. However, process waste in the northeast region of the Preserve and Methylosmolene was detected in their smokestack emissions.
Kasios now claims that the analysis was flawed. To combat these conclusions, Kasios has launched their own “investigation” into the Pipit situation, and they are now reporting that there are plenty of Rose-crested Blue Pipits happily living and nesting in the Preserve. To back up this claim, they have provided a set of Pipit bird calls, recently recorded across the Preserve, with locations of where they were recorded. Clearly, they claim, the Pipits are a thriving population, and Kasios will provide even more supporting evidence as their investigation proceeds.
The Pangera Ornithology Conservation Society is at their wit’s end at what to do about this turn of events. The townsfolk and Preserve rangers seem satisfied that the recordings back up Kasios’ claims. Mistford College does not have another Pipit expert they can call upon for help. But, they do have a collection of bird calls from the Preserve that has been vetted by various ornithology groups as having accurate identifications. They have heard that new techniques from machine learning and visual analytics can be applied, where these calls could be classified and analyzed using these technologies.
Research Questions
Using R programming, techniques from visual and geospatial analytics will be applied to answer the following research questions:
1. |
What are the patterns, trends and anomalies across the bird species in the Preserve over the time of collection? |
2. |
What happened to the state of the Rose Pipits? Are Pipits actually thriving across the Preserve? |
3. |
Does the set of bird calls supplied by Kasios support the claim of Pipits being found across the Preserve? |
