Click to verify
Click any point. The right-hand panel shows model attributes plus a Street View link to confirm before citing.
Crosswalk segmentation
Crosswalk polygons from the U-Net mosaic.
Each polygon is a connected paint region detected by the segmentation model. Filter by mosaic region, click a polygon to see its area and verify it in Street View.

More functionality is on the way.
The explorer will grow side-by-side with planning workflows: corridor draw-and-export, confidence threshold filtering, crash-data overlays, and downloadable bundles per neighborhood. Ideas for what you'd want here? Tell the team.
