"NCI GIS Portal is a web-based station for interactive mapping and visualization of cancer related geo-spatial data. The portal combines Geographic Information Science (GIS) principles and tools to harmonize relatively large and multi-dimensional datasets, including population-based cancer statistics and behavioral, environmental, clinical, socioeconomic, and policy data."
"How NCI Uses GIS
Geospatial methods and tools are used in a variety of NCI programs to analyze and visualize geographic variation in cancer incidence and mortality and explore contextual influences on cancer risk."
