Geographic & Contextual Measures Core (GCMC)

To enhance the utility of existing population and clinical studies by making place-based measures of traditional environmental stressors, neighborhood contextual variables, and social constructs available and accessible to all Center members.

GCMC provides expertise in GIS, creation and interpretation of contextual variables and social constructs. This Core convenes working groups of investigators working on related topics to identify common data needs, share resources, and subject matter expertise. GCMC will also provide the necessary infrastructure to support educational activities such as seminars and workshops of relevance to Center

Scientifically, GCMC promotes the integration of the Center’s Research Cores (metals, organics, particles). It also provides data products to Center investigators that can be used as preliminary data in grant proposals or as exposure data, confounders, or modifiers in Center research projects.

  • Harvard Graduate School of Design GIS Resources
  • Harvard Geospatial Library
  • Harvard Map Collection
  • Health Map: Health Map brings together disparate data sources to achieve a unified and comprehensive view of the current global state of infectious diseases and their effect on human and animal health. This freely available Web site integrates outbreak data of varying reliability, ranging from news sources (such as Google News) to curated personal accounts (such as ProMED) to validated official alerts (such as World Health Organization). Through an automated text processing system, the data is aggregated by disease and displayed by location for user-friendly access to the original alert. HealthMap provides a jumping-off point for real-time information on emerging infectious diseases and has particular interest for public health officials and international travelers.
