On September 19 2019, I gave a lecture in the Methods: Mind the Gap Webinar Series of the National Institutes of Health Office of Disease Prevention (ODP): Geospatial data for healthy places: Building environments for active living through opportunistic GIScience. A video of the lecture and slides is posted here
In this lecture, I discuss the role of geospatial technologies and data in facilitating quasi and natural experiments about built environment factors that encourage active living. I also extend this idea to the concept of geographic information observatories: systems for ongoing data collection and analysis that facilitate opportunistic science that can leverage real-world events via ongoing observation, experimentation, and decision-support.
