Cartographic Modeling Lab (CML)

Welcome to the Cartographic Modeling Lab (CML) at the University of Pennsylvania.  The CML is a research unit within the Penn Injury Science Center (PISC). The CML specializes in applying geographic information systems (GIS) software and hardware to digitally link data and geography to generate spatial databases, maps, spatial statistical analyses, and mapping applications, providing a useful way to reveal spatial and temporal relationships among data.


By using GIS to visualize geographic relationships that affect health outcomes, public health risks, disease transmission, access to health care, and other public health concerns, the CML conducts spatial research, policy analysis, and develops mapping applications of value to investigators at Penn and beyond.

What is GIS

Geographic Information Systems, or GIS, is a system of computer software, hardware, data, and personnel. GIS can be used to store, analyze, and visually present a computerized “layer cake” of information—such as the total number of adults, hospitals, or grocery stores—that is tied to a geographic location—a county or a zip code, for instance. GIS analysis and maps can reveal relationships, patterns, and trends not visible through tables, charts, or other means.

GIS Services

The CML has an extensive selection local, national, and global geospatial data. With our services in geospatial database development, static and interactive mapping visualization, analysis design, and spatial analysis and statistical expertise, we can help guide from research inception to finished project.
