Data Repositories

At Ge-iSEE, we are building a robust, comprehensive, multi-source environmental exposure data platform that spans both local and global scales. This initiative is designed to advance research that drives evidence-based strategies for improving urban environments and promoting healthier communities now and in the future. Through collaborations with similar global initiatives, we aim to establish standardized environmental measures, offering researchers an unparalleled opportunity to investigate the intricate ways these factors influence public health. The datasets we create will be pivotal in facilitating collaborative, cross-disciplinary research with academic partners worldwide.
