Quantitative analysis of gorilla movement and R-Stat
Posted by smathermather on November 21, 2016
At this point in my career, it is a rare request that intimidates me. Most requests are either solved, largely solved (and I know how to find the answer), or broadly improbably / excessively expensive.
This is a nice place to be. I have a bit of calmness with every request, a vision for how to execute, or the escape valve of saying, “That’s harder / more expensive than you think. Perhaps we should look at these alternatives.”
Recently, I got a request that was tougher — a theoretically possible project at the edge of my knowledge domain, a desire to deliver at any reasonable cost, and no clear sense of who to ask for help.
Specifically, how does one take volumes of gorilla tracking data, and make sense of the behaviors and intentions implicit in their movement? Many know the story of Dian Fossey, the primatologist who lived with the mountain gorillas in Rwanda. What many may not know, is her research continues in Rwanda at Karisoke Research Center (and has continued for 50 years), following the troops of gorillas in Rwanda, and the project has expanded quite a bit under auspices of the Dian Fossey Gorilla fund:
I have the privilege of being sponsored by the Cleveland Zoological Society to got to Karisoke, observe the research, and help where needed with GIS infrastructure development and geospatial analyses. I am excited beyond belief.
So, what’s the test here? I know how to do geospatial infrastructure. Ask me to improve infrastructure and I have a decade of experience chasing down these problems, trying out different technologies, developing new ones. I also know how to perform advanced analyses. I pride myself on my analytic skills, even as I’ve moved from analyst to programmer to manager, etc.. But, I’ve never done the more advanced quantitative analyses of movement necessary to deepen understanding beyond work already done at Karisoke. Lots of great minds have already been looking at the data for years and decades. The basic question in my mind — how can I meaningfully help?
Thanks to my colleague Dr. Patrick Lorch, I have some sources. Pat did his thesis work studying the movements and behavior of Mormon crickets in the western US, and his experience with quantitative analysis of movement is directly applicable.
In short, the next few blog posts will be about the apparently incomparably beautiful nation of Rwanda, mountain gorillas, R-Stat, and adehabitat. There will be PostGIS mixed in for good measure. Stay tuned.
