GIS Researchers Receive Grant to Explore Spatial Data Error
Two researchers in UT Dallas’ School of Economics, Political and Policy Sciences will explore uncertainty in spatial data with a grant awarded by the National Institutes of Health.
The project focuses on documenting, visualizing and utilizing data error and uncertainty information in spatial analysis, said Dr. Daniel A. Griffith, Ashbel Smith Professor of geospatial information sciences (GIS) and the principal investigator. Dr. Yongwan Chun, an assistant professor of GIS, will serve as co-investigator on the project.

New Analysis Method Uncovers Factors in Vehicle Burglary Rates
By applying a new method to modeling spatial patterns of crime, University of Texas at Dallas researcher Dr. Yongwan Chunanalyzed vehicle burglaries in Plano, Texas, and found factors associated with increased and decreased burglary rates.
Chun, an assistant professor of geospatial information sciences (GIS) in the School of Economic, Political and Policy Sciences, used GIS data from the Plano Police Department to analyze the 17,549 vehicle burglaries that occurred from 2004 to 2009 in the Dallas suburb.
The method Chun applied is an extension of eigenvector spatial filtering (ESF), which was originally developed by two UT Dallas GIS faculty members, Dr. Daniel Griffith and Dr. Michael Tiefelsdorf. Chun’s study was published online in Geographical Analysis in April.
