The CSR is pleased to report the recent publication featuring the work of our very own
Nathan Mosurinjohn, along with Calvin’s Professor of Geography, Jason VanHorn. Professor VanHorn’s specialty is terrorism geography, and in the summer of 2008 he began working with Nathan on a methodology for safeguarding politicians and other VIP’s from sniper fire using 3D modeling.
GIS (Geographic Information Systems) are frequently used in crime prevention strategies, but many approaches only make use of 2D data. In this paper, Professor Van Horn and Nathan examined 3D modeling possibilities using the tools available in GIS and Google Sketch-Up. Their goal was to be able to calculate every position sniper fire could potentially come from a given particular VIP location.
To test this methodology, the burial site of President Ford, found at the Gerald R. Ford Museum, was selected, being a location that has hosted many prominent people in the past, including Vice President Dick Cheney at President Ford’s burial. Nathan first built a digital 3D model of downtown Grand Rapids using Google Sketch-Up. He researched aerial photographs, maps, and records containing specific heights of buildings to aid him in this task. Click here to see a video of this 3D model. Do you recognize downtown Grand Rapids?
Using this model, Professor VanHorn and Nathan were then able to construct a viewshed which shows all of the places from which a person could be seen if they were to be standing at a specific location. Nathan and Professor VanHorn also researched the maximum firing ranges of different weapons and built a model which demonstrated the maximum distance that a weapon would have to fire to reach a designated area (see image below).
This instrumental research gives an example of how 3D modeling capabilities can be used in terrorism research and personnel protection, and how useful it is to conduct these analysis in 3D instead of 2D maps.

As the end of the school year approaches, the CSR staff is making plans for the future.
Several Research Assistants are leaving CSR to start new chapters in their lives. Here is what they are up to!
Using data from the Kent County Congregations Study, CSR staff will showcase emerging tools and methods for visual data analysis.
