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, a favorite bird of Mistford residents and Boonsong Lekagul Nature Preserve visitors. Kasios supposedly used the banned substance Methylosmolene in their manufacturing process. They surreptitiously dumped 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 and biased. 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.
Last year, an ornithology grad student from Mistford College named Mitch Vogel discovered the plight of the Pipit and carried out an investigation. Normally, we would call on Mitch again to help validate Kasios’ claim. Unfortunately, Mitch is working far from Mistford in a remote area without internet access for an extended time and cannot be easily reached!
The Pangera Ornithology Conservation Society, who sponsored Mitch last year, 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 to situations like this. Perhaps, the calls could be classified and analyzed using these technologies, and reviewed when Mitch returns.
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? |
