Identified opening envelope
1 opening1 count
Opening envelope visually identified. Image station is not a physical distance; dimensions remain 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.
