Mapping 14 behavioral outcomes The researchers built the atlas after reviewing scientific literature and interviewing experts from NASA, academia, and industry. “The connection between habitat and behavioral health has not been made in this format before,” Lin emphasized. NASA-inspired risk mapping HECIA uses a format inspired by NASA’s directed acyclic graphs, or DAGs. The new atlas applies the same approach to behavioral health. The team cautions that HECIA does not prescribe one universal habitat design.
