Check my streetHas anyone measured the invisible world where you live, work or travel?
Type an address or a place. Your text goes from your browser straight to Photon, the OpenStreetMap geocoder, never to our server. We only receive the ids of the 19 hexes around that point, about 500 metres across, and answer with what phones actually measured there. Nothing you type is stored.
How to read the answer
Measured means at least one phone running Invisible Atlas physically passed through that hex and its upload was accepted.
Layers are the kinds of measurement taken there: Bluetooth, WiFi, cellular, GNSS sky, magnetic field, air pressure, night light, sound level, spectrum.
Signals per pass is how many radio devices a passing phone typically hears. Under 5 is shown as "fewer than 5".
Not measured yet is honest and common. Tap "Go measure it" and your phone becomes the first.
