Generated 2026-10-02T06:09 UTC from every measured hex whose place name resolves to this city. Hexes without a resolved name are not counted, so these are lower bounds. Cite as: Invisible Atlas, Invisible World Report, Săvădisla, 2026-10-02, blescan.sevinhub.com.
The phones that measured Săvădisla have caused 1 real provider-fulfilled units so far, 1 of them trees. Attribution is by phone, not by hex, because a phone earns across every place it maps.
Method
Each phone converts its position to an H3 resolution-9 hexagon on the device; only the hexagon and the readings leave the phone. Bluetooth and WiFi are counted from hashed identifiers, never listed. Cellular is the serving signal level 0 to 4. GNSS is carrier-to-noise density. Night light and sound are deliberate readings taken by a person on purpose; sound records a number, never audio. Network speed is measured only when a user starts a test. Averages are over hexes that carry the layer, not over the city's area. Place names come from a reverse-geocoder and cover part of the hexes, so counts are lower bounds. Nothing is interpolated.

above is an exact count over the same database Explorer and
Live Map read, never an estimate. Some pages are refreshed on a schedule rather than on every visit
(Records every ten minutes, Heartbeat every minute, Open data once a day) and say so. Node counts only, never identities.
