Saint Louis University has received a $1 million grant from the National Geospatial-Intelligence Agency (NGA) to create a satellite calibration network to improve the accuracy of satellite observations and the geospatial tools used to monitor global change, infrastructure resilience, and natural disasters such as landslides, volcanic eruptions, and flooding.
The project, “Developing global InSAR solutions for change detections with enhanced regional calibration,” is led by Vasit Sagan, Ph.D., deputy director of Taylor Geospatial Institute (TGI) and associate vice president for geospatial science at Saint Louis University. Jeremy Maurer of Missouri University of Science and Technology and Jackson Cothren of the University of Arkansas are co-principal investigators.
The project will develop an absolute accuracy model for Interferometric Synthetic Aperture Radar (InSAR) to characterize the accuracy of global InSAR deformation models.
The grant will also fund the establishment of satellite calibration sites across the Midwest. Sagan said there are similar calibration sites in other countries and regions of the U.S., but none in the Midwest.
