Camera-driven Mapillary coverage (z0–5 overview points from orbit, z11–14 ground-clamped sequence lines below 60 km), per-sequence image cones, an embedded MapillaryJS viewer bridge with a camera-follow mode, sprite icons for map features, and a query engine that turns a plan into a streamed z14 tile fan-out.
