Recognizing mapmakers

“Recognizing mapmakers” is the motto of the National Geographic Map Awards. We are talking serious mapping, by which I mean the professional design of thematic maps that are used for research, planning, and decision-making in a broad range of disciplines.

I am extremely pleased to report that Brad Carter, a parttime student in our Master of Spatial Analysis (MSA) program, won the 2nd place prize of the 2012 National Geographic Award in Mapping. Brad created his award-winning map on “Broken Windows & Violent Crime in Philadelphia” as his final assignment in my course on “Thematic Cartography and Geovisualization” in November 2011. A high-resolution PDF of Brad’s map is available from the CartoNews blog of the American Association of Geographers’ Cartography Specialty Group.

With his map, Brad illustrates crime theories by superimposing social factors (single-mother households), environmental factors (vacant buildings as a proxy for urban decay), and crime incidents. The combination of data from the US Census, the Crime Reports Web site, and from Pennsylvania Spatial Data Access allows the map reader to determine whether the “broken windows theory” can explain the distribution of crime in Philadelphia. The uncommon dasymetric mapping technique used in the large-scale map places aggregate information only in those areas where the phenomenon is likely to exist, instead of uniformly distributing it across the entire enumeration unit. A crime analyst himself, Brad is creating and using this kind of map to support prevention programs and policing operations at Durham Regional Police. In the MSA program, he is working with me on a locally weighted heat vulnerability index (more to come soon;-).
