Last Photograph Before Change
Which protected places lack recent visual documentation after a public change signal?
Compare photograph dates with map edits and news around heritage sites to identify documentation gaps.
01
Why this pairing matters
The non-obvious connection
The meaningful gap is not simply ‘old photograph’; it is old visual evidence after another public system reports nearby change.
02
The demonstration
One visible reveal
A timeline places the last known public image before a cluster of later map edits or reports, then asks for human documentation.
03
Three-hour boundary
The smallest credible version
Ten sites, curated public images, map-change metadata, news results, and a call-to-document queue.
04
Claim boundary
What the data cannot establish
Upload time may differ from capture time, and neither map changes nor news prove that the site itself changed.
