As climate change accelerates, and natural disasters become more frequent and severe, there is a growing need for governments, companies, and nonprofits to have a clear understanding of what is happening on the ground. High-resolution satelliteimagery and historical imagery archives are growing increasingly crucial for efforts to evaluate the magnitude of disasters and assist hard-hit areas. It is more important than ever for organizations to work together with these comprehensive datasets for more efficient disaster response. Andy Carroll, CTO of Skytec and Matthew Snyder, Engineering Manager for the Chattanooga Department of Transportation, discuss how they use Planet's high-resolution, high-cadence satelliteimagery to create a mapping application and tornado impact index to help communities recover from severe tornadoes that swept through the Tennessee Valley in April 2020.
