Satellite object detection
For pool builders, insurers and county offices: find homes with a pool, or an extra building, that the public property record does not show. Every number below is a real measurement — a sample size and a control test behind it, not a sales pitch. One tile below shows a real aerial photo with a detection on it.

Detection accuracy, measured
Out of every 100 homes with a real pool, the detector finds about 38, and about 1 in 100 flags is wrong.

How a detection works
A real aerial photo with the detector's own flags marked, next to a color test you can try — some misses included on purpose.
-
Transfers to other counties
Same detector, no retraining, tested in three counties. It found pools about as well in Florida, worse in San Diego.

The same photos also flag roof type, extra buildings and solar panels — every result shown, including the ones that did not work.
