Data is Plural: “Leveraging high performance computing, remote sensing, geographic data science, machine learning, and computer vision,” Hsiuhan Lexie Yang et al., researchers at Oak Ridge National Laboratory, have “partnered with Federal Emergency Management Agency (FEMA) to build a baseline structure inventory covering the US and its territories to support disaster preparedness, response, and recovery.” The dataset and interactive map trace the outlines of 125 million buildings and, in many cases, contain the building’s address, occupancy class, usage type, height, elevation, and other attributes. They also provide information about the imagery used to identify the structure.”
