Developing decision support tools
SRP researchers and trainees have developed a statistical mapping software that enables decision makers to factor uncertainty into risk assessments.The Bayesian Maximum Entropy Graphical User Interface (BMEGUI, pronounced B-M-E gooey) is a free, easy-to-use software tool designed to help users map contaminants in the environment, perform risk assessments, and show patterns of disease over time.
Based on data from a variety of sources such as satellite imagery, mathematical models, and on-site observations, the software allows researchers to predict movement of contaminants in the environment and select the best locations to monitor.
RTC investigators and trainees have mapped contaminants including arsenic, tetrachloroethylene (PCE), and mercury in air, groundwater, and rivers in North Carolina and beyond using BMEGUI. The software has also helped researchers to make predictions about the distribution of Superfund contaminants at sites where there are few monitoring stations and limited data.
- The software includes several online tutorials and a comprehensive user manual.
- No programming experience is necessary and the outputs are compatible with ArcGIS.
Visit the BMElab for more information about BMEGUI and ongoing projects.
