Glass Sky Scan ^new^

Maps the exact physical contour of the glass to detect sagging or shifting.

The digitization process is highly sophisticated. Special scanners are used to create high-resolution digital images of the glass plates. The DASCH project (Digital Access to a Sky Century @ Harvard) has been particularly critical, having scanned over 429,000 direct images from the collection for its final data release in 2024. glass sky scan

If you live in a city, you know the feeling. You step out of a subway station or turn a corner in the financial district, look up, and the sky isn’t blue—it’s a fractured mosaic of silver, blue, and charcoal. Maps the exact physical contour of the glass

To understand the necessity of a glass sky scan, one must understand how structural glass behaves over time. Unlike steel or concrete, glass is highly susceptible to localized stresses that are invisible to the naked eye. Several factors can compromise structural glass: The DASCH project (Digital Access to a Sky
