Every dimension belongs to an object and a drawing. Original room numbers, object marks, printed values and source regions stay together—even when the answer is unresolved.
464 of 464 photographs have extraction records, containing 27,517 properties. Initial image review is not exhaustive extraction: 0 photographs have passed the full-region check. 66 numbered sheets are reconciled. Modeling and architectural registration are separate work; these counts do not establish a complete building.
Download the structured register (JSON)Original sheet identity has not yet been reconciled.
Extraction: Reviewed · extraction partial. Partial: façade opening identities/counts and selected printed datums. Drawing number, registration and opening dimensions still unresolved. Reuse of existing text/registered property data only; no new image review. Main upper wall corners and visible floor datum courses. 69 previously identified Broadway opening instances, individually repicked visible envelopes. Main coping/parapet/cornice/frieze/F3 belt envelopes. Basement dashed windows, sidewalk/finish-grade guide lines, visible boiler reference. Text-first physical-pilot gate 3 audit; existing reviewed plan, elevation and section records reused without reopening an archival image. Page-right 4/11 metric/cardinal conflict audit; Existing B02 visible elevation envelope, master pixels about x1199–1298/y1311–1437; opening mark was not independently decoded from this elevation. Page-right 4/11 metric/cardinal conflict audit; Existing B09 visible envelope, master pixels x2763–2864/y1318–1444; metric alternative only, not a confirmed key match. Page-right 4/11 metric/cardinal conflict audit; Right-end street label fixes right as south/Madison. Partial timed visual review: Text-only prior evidence inventory; catalogue labels are discovery-only and prior verified identity retained. Partial timed visual review: Source-local architectural evidence only; no physical registration, installed quantity or accepted geometry. Existing verified measurements omitted; conflicting locator readings preserved. Partial timed visual review: Bounded target crop inspection; source-local printed/observed evidence only.
