Sagan has served as TGI’s Founding/Acting Director since its April 2022 launch, leading TGI’s efforts to harness the power of partnership with industry, government agencies, and research entities to address some of the world’s greatest challenges. In its inaugural year, Sagan has led TGI and build it into a world-class research consortium, created a robust geospatial data infrastructure that empowers consortium faculty, and established numerous incentive programs. In TGI’s first year, Sagan assisted in recruiting dozens of geospatial leaders to TGI’s partner institutions and secured nearly $20 million in external grants. The most comprehensive and holistic geospatial research community is now in St. Louis and comprised of eight of the Midwest’s outstanding research institutions. Everything happens somewhere, and the science of location is more critical now than ever in our digital age. We’re harnessing the power of partnership with industry, government agencies, and research entities to not only grow talent but develop core geospatial science and adjacent fields that enable positive impacts on some of the world’s greatest challenges. https://taylorgeospatial.org/

We develop algorithms to characterize the changes to Earth's land cover and integrate remote sensing observations with model-based approaches to understand the impacts of climate and land use changes on the water and energy cycles and ecosystems from local to global scales. The lab is interested in developing new methods that improve the information content of satellite data for improved LCLU mapping. To this end, we use multispectral, hyperspectral, and active microwave (SAR/PolInSAR/InSAR) and field observations to map crops, invasive plants, minerals and InSAR data to monitor land subsidence from anthropogenic activities, which are unified by a central theme: monitoring the impacts of climate and land-use changes on the environment using remote sensing and GIS as the primary tool.
