You see smoke on the horizon. Where is it? SmokeBearing answers with the
same method fire lookout towers have used for a century: cross-bearings.
SIGHT IT
- Aim your phone at the smoke and take a bearing — true heading, GPS
position and a reference photo are recorded in one tap
- A bearing line is drawn on the topographic map instantly
CROSS IT
- Move sideways, take a second bearing, and the two lines cross
- The intersection is the estimated smoke position — with an honest
uncertainty fan, never a fake pinpoint
- Distance from you, coordinates in decimal or DMS, ready to share
READ THE WIND
- Smoke drifts. The crossing point is where the smoke is now — not
where the fire started
- Live wind direction and speed are drawn over the map, so you can see
which way the plume is running
- The likely source is marked upwind of the smoke, as a zone rather
than a false pinpoint
WORKS ANYWHERE
- No fire-data feed required: the bearing fix is measured by your
phone's own compass and GPS, and works fully offline
- Keep a log of every fix with photos and observation points
- All data stays on your device
SmokeBearing gives a rough cross-bearing estimate; error grows with
distance. Always follow official emergency information for evacuation
and reporting decisions. No ads, no subscription: one purchase, forever.
