PHONE FIELD CAPTURE

Calibration

Location and water-level calibration are separate First save or update the observation location. Stop there if you only have time to position the site, or continue with a repeatable photo and optional measured height. GPS accuracy is recorded, not assumed. Phone altitude is not used as a water-level measurement.

SYNC AUTOMATICReal records automatically reach your private RiverPulse desktop record. Test records stay on this device.

Calibration maturityNot calibrated

0 observations

CHECKING FOUR-HOUR WINDOWWaiting for Fairlight and Cattle Flat history.

A location-only record positions the observation point approximately between the gauges. A photo calibration adds visual evidence over time. Neither one infers the local water level.

NO LOCAL OBSERVATION YETYour next saved phone observation will appear here and on the map as an approximate private marker.

Test record — I am not at the calibration siteUse this when checking the phone workflow elsewhere. Test records never affect calibration maturity, the pulse marker or the map, and can be deleted after checking.

Capture phone locationHold still with a clear view of the sky. River Pulse samples for up to 20 seconds and keeps the most accurate horizontal fix.

Arrival-time prediction is intentionally disabled until local calibration observations are sufficient. River Pulse should not imply predictive precision it has not earned.
