Choose a postcode or small district. Walk or ride through its real hex grid and watch verified coverage fill in. A completed threshold can unlock a matching sensor cause when one exists, but it never creates an extra payment.
Everything on this map was physically detected by a phone that was actually there. Nothing is modelled, estimated or filled in.
This is the live view. The network also records GNSS sky, WiFi and cellular spectrum, magnetic field, air pressure, night light and sound level. Those layers, plus search-by-area for anywhere on Earth, live on the Explorer.
Every line is a real reading sent by a phone that was there. Each layer is drawn against its own range, because a hectopascal and a decibel share no scale, so heights are comparable within a line and never between two. Nothing here is smoothed, filled in or carried forward.
