Once you are zoomed in on a specific location, you can click on the blue lines (sidewalks), the magenta lines (crosswalks), or the circles (ramps) to view details about the feature. A sidebar will open showing relevant attributes. For sidewalks, attributes displayed will include the surface material (mixed, asphalt, concrete, brick, etc.) and type (if it’s a path, grade-separated or unknown). For crosswalks, other attributes include if the crosswalk is raised, if it includes pedestrian signalization, and the type (unmarked, decorative, diagonal, etc.). For ramps, other attributes include the ramp’s position (island/median, mid-block, multi-directional, etc), and if the ramp has a detectable warning surface. To learn more about the attribute terms for pedestrian features, view the visual glossary.
