Street Level Imagery

Geo-referenced 360-degree panoramic photography captured from vehicles or pedestrians at street level, made widely available through services like Google Street View and Apple Maps Look Around. Street level imagery provides a rich visual record of the built environment — sidewalks, curb cuts, tactile paving, signage, storefronts, crosswalk layout — that is not conveyed by traditional map data. It has been used to crowdsource and automate accessibility audits (e.g. Project Sidewalk) and, increasingly, as a data source for AI systems that generate accessible descriptions for blind and low-vision users.
