About GISSA

GISSA is an active laboratory engaged in progressive GIScience research. Leveraging state-of-the-art spatial analytical tools for geospatial analysis, geovisualization and spatial process modeling, GISSA both develops and implements these tools for engaging in evidence-based decision making, policy evaluation and contract-based industry research.

GISSA was founded and is directed by Tony H. Grubesic, Associate Professor of Information Science and Technology at Drexel University.

Recent work includes the development of spatial decision support systems (SDSS) for evaluating the vulnerability of critical infrastructure systems in the United States, the development of a spatio-temporal surveillance framework for visualizing heterogeneities in violent crime "footprints" in urban areas, examining the global accessibility of major world airports, the implementation of predictive statistical models to forecast the spatial provision of broadband services throughout competitive telecommunications markets in the U.S., and the development of a mathematical programming framework for evaluating the efficiency of federally funded air transport subsidies to rural and remote communities in the United States.
