# Taş Köprü — Beyşehir regulator bridge

Published 42m by 6.35m dimensions, fifteen openings and fourteen intermediate piers are sourced. Heights, precise arch profiles, gate depth, screw/handwheel dimensions and stone joints are estimated from photographs. Gate positions are illustrative, not live operating status. Georeferencing follows a generalized OSM span, not survey control. The bridge deck is z=.10m so the virtual walking camera remains on the crossing; lower masonry is below the atlas's flat water datum and is fully visible in the standalone viewer. No field-access guarantee.

Coordinates and orientation are baked into metric local geometry. Origin: (31.7227783299, 37.6806213634).
The GLB contains the landmark only. Preview staging is not exported. Selected material appearance uses reviewed owner photographs; other textures are procedural. See photoAppearance in metadata and /models/materials/photo-2026-10-04/provenance.json.
