The USA Structures Dataset provides a comprehensive geospatial database of over 125 million building structures across the U.S. and its territories, capturing every structure larger than 450 square feet. Developed by Oak Ridge National Laboratory (ORNL) through the integration of advanced geospatial science, high-performance computing, and AI, this dataset processes over 1.1 petabytes of imagery. It serves as a valuable resource across various fields, supporting tasks from urban planning to emergency response with detailed location-based data. Its precise, accessible structure facilitates cross-agency collaboration, making it an essential tool for federal, local, state, tribal, and territorial organizations. The dataset accelerates tasks like damage assessments and recovery operations, aiding communities in recovering from disasters efficiently.
