Join us to explore what it takes to map pedestrian infrastructure across Washington (~180,000 km²)! We’ll dive into the technical stack that enables scalable mapping and how human+AI techniques accelerates the process while ensuring data quality. Learn how we developed a first-of-its-kind open, uniform pedestrian network dataset—pioneered by the Taskar Center for Accessible Technology, in collaboration with Gaussian Solutions LLC, and sponsored by the Washington State Legislature.
