The Wilson Map Lab continues a journey that I started 30+ years ago. This journey started with the founding of the Geographic Information and Analysis Center (GIAC) at Montana State University in 1988 and continued with the founding of the GIS Research Laboratory at USC in 1997. This new lab supersedes the GIS Research Laboratory and reflects both the rapidly evolving web-based collaborative landscape we now live and work in and the growth of the USC Spatial Sciences Institute, which today is home to 12 faculty, eight support staff, and over 300 students.
The seeds for my research interests and success were planted long before the establishment of GIAC in 1988. My completion of a M.S. thesis in spatial demography (1979) and a Ph.D. dissertation that combined elements of historical geography, civil engineering, environmental modeling, and geomorphology (1986) speaks to both the breadth of my interests and my willingness to look for the spatial advantage in almost any setting. My work with my own mentors over the first part of my career instilled in me the lifelong goal of using teaching and student participation in research as a way to build capacity and grow leaders in the academic, private, public, and not-for-profit sectors.
I firmly believe the best days are still ahead of us and that the spatial sciences will emerge as a pervasive, cross-cutting and enabling discipline (much like statistics is today). My new virtual lab provides a vehicle to connect faculty, staff and students with projects focused on the modeling of environmental systems, human activity and the built environment, and the environmental and social determinants of human health. These themes fit nicely under the “map” banner because maps promote the production and sharing of knowledge and are embedded in nearly everything we touch.
I work on a variety of projects simultaneously. Most are collaborative in that they involve working with faculty, staff and student colleagues.
1. Projects I embark on because they are fun:
I have sustained a lifelong interest in geomorphometry by conducting a large number and variety of terrain analysis and modeling studies and by writing extensively on these topics. I am currently working on a review article for Progress in Physical Geography and a new digital terrain modeling book for John Wiley and Sons. I have recently co-authored a couple of articles on related topics with Tian-Xiang Yue and colleagues in the Chinese Academy of Sciences.
2. Projects supported by grants and contracts (which may be fun to tackle, as well):
These projects currently include building mobile apps and cloud-based data repositories and mapping platforms to gather and visualize crowdsourced information about places of worship and congregations across the Los Angeles Metropolitan Region, building detailed, photorealistic 3D models of USC’s University Park Campus, and providing place-based assessments linking the built environment, environmental exposures and socio-economic conditions to human health outcomes in studies focused on adolescent smoking vulnerability to tobacco use and marketing across life in one project and maternal stress and children’s obesity risk in another project.
My collaborators include Richard Flory and Brie Loskota (USC Center for Religion and Civic Culture), Kyohyouk Kim (USC Spatial Sciences Institute), Fred Lurmann (Sonoma Technologies, Inc.), and Rob McConnell, Rakesh Ghosh, Genevieve Dunton, Frank Gillilland, Zhenghua Chen, Ed Avol, and Myles Cockburn (USC Department of Preventive Medicine).
3. Student-led projects (which are often fun, as well):
I have the great privilege to work with many students on a great variety of topics. Some the students suggest by themselves, some we develop collaboratively, and all produce some useful knowledge. I am currently working with the following students on Ph.D. dissertation and M.S. thesis projects:
Avery Rose Everhart, Population, Health and Place Ph.D. Program. Dissertation title: Contested care, contingent community: Placing US transgender health care in the global context through a rights-based approach to health.(Co-advisor with Dr. Laura Ferguson, Department of Population and Public Health Sciences, University of Southern California).
Leo Lerner, Population, Health and Place Ph.D. Program. Dissertation title: To what extent can wicked problems of health and place be addressed through clumsy solutions? Three experiments in redistributing networks of knowledge production (Co-advisor with Dr. Lourdes Baezconde-Garbanati, Department of Population and Public Health Sciences, University of Southern California).
Cari Porter, M.S., Geographic Information Science and Technology Program. Thesis title: Place-based flood vulnerability in the Sacramento-San Joaquin Delta region.
Mengya Xu, Population, Health and Place Ph.D. Program, Dissertation title: Availability, diversity, and structure of the retail food environment and associated disparities in Los Angeles County. (Co-advisor with Dr. Kayla de la Haye, Department of Population and Public Health Sciences, University of Southern California).
Yan Xu, Population, Health and Place Ph.D. Program. Dissertation title: Personal PM2.5 exposure assessment of low-income Hispanic pregnant women in Los Angeles. (Co-advisor with Dr. Rima Habre, Department of Population and Public Health Sciences, University of Southern California).
Li Yi, Population, Health and Place Ph.D. Program. Dissertation title: Investigating daily effects of activity space-based built environment exposures on energy-balance behaviors in low-income Hispanic women of childbearing age. (Co-advisor with Dr. Genevieve Dunton, Department of Population and Public Health Sciences, University of Southern California).
4. Projects for which funding proposals have been submitted (which will be fun if they are funded):
My career seems to have come full circle during the past three decades. I had fantastic success early in my career by teaming up with more senior colleagues such as Gerry Nielsen and Steve Custer and now I find fantastic young colleagues wanting to write proposals and to collaborate with me. There are two proposals under consideration for funding now that I am particularly excited about and I would love to see funded so we could tackle the work itself:
A New Approach for Understanding High-Risk Geospatial Decision Making
Jordy Hendrikx, Department of Earth Sciences, Montana State University, Jerry Johnson, Department of Political Science, Montana State University, and John P. Wilson, Spatial Sciences Institute, University of Southern California, PIs

Modeling Environmental Systems
The various projects organized under this theme span my early career at Montana State University, my career at USC, and my visiting appointment in the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences. The longest running thread has focused on digital terrain modeling and the pending publication of my new book (Environmental Applications of Digital Terrain Modeling – Wiley, 2018) in many ways represents the culmination of 30+ years of work on the methods and applications of digital terrain analysis and modeling. Much of my early work at USC under the environmental systems modeling theme was part of the Green Visions for 21st Century Southern California project (see below for a series of reports that span hydrologic modeling and biological conservation and restoration, and some of my recent work has involved modeling the spatiotemporal variability of carbon stocks and fluxes in China.

Modeling Human Activity and the Built Environment
The imprint of people can be found everywhere nowadays – in pristine and celebrated environments like Yellowstone National Park, in our crop and grazing lands, and of course in large metropolitan areas like Los Angeles. This has spawned a variety of projects on 2D and 3D routing, the spatial distribution of tree cover on single family lots in the Los Angeles Metropolitan region, the 3D visualization of a university campus and most recently, the efficacy of Operation Smile’s missions in Mexico and strategies for improving their reach in the coming years.

Modeling the Environmental and Social Determinants of Health
The various projects organized under this theme use a variety of spatial analysis and modeling approaches with geographically referenced data to explore the relationships connecting people, location, time and health. The location is typically cast in terms of their social (i.e. various socioeconomic and demographic variables), behavioral (i.e. lifestyle choices focused on diet, nutrition, and exercise) and environmental characteristics. The latter may include beneficial features such as the quality of the local housing stock and availability and distance to green space as well as adverse traits connected with crime, pollution (i.e. PM2.5 concentrations), toxic substances (i.e. pesticide applications), and UV exposure, among others. This information is used, in turn, to help guide disease prevention, health promotion, and better health care service planning and delivery.
