Comparing the same facade across two visits
A single flight answers “what does it look like now?” Two flights answer “what changed?” That second question is where most photo handoffs fail.
Why one visit is not enough
Facade and roof work is rarely a one-off. A crack, stain, or seal that looked fine last year may need action this year. If each survey lives in its own zip or folder, the earlier visit is hard to open beside the new one — so people guess from memory or the PDF.
What “compare” should mean
The same place
The same place on the building, not two random files with similar names.
Two dates
Two dates you can switch between without leaving the record.
History on the spot
A flag or note that stays with the spot so the next person sees the history.
Enough to act
Enough context that a contractor or surveyor can act without the full archive.
What usually gets in the way
Filenames by date. Separate email threads. A report that describes change in words but does not show the two photos together. The second visit arrives; the first is already buried.
How Skycat Photo fits
Skycat Photo keeps visits with the building. Open the same spot side by side across dates. The earlier flight stays on the map — ready when you need it, not lost in last year’s inbox.
