GPS Accuracy (m)

gpsAccuracyM on a FieldMeasurement quantifies the precision of the GPS reading. A high gpsAccuracyM (poor GPS signal) means the distance-to-well calculation in gpsDistanceM is less reliable. Data reviewers can use gpsAccuracyM to contextualize a gpsFlagged result: a measurement flagged due to large gpsDistanceM but also showing large gpsAccuracyM may be acceptable if signal conditions were poor rather than indicating the wrong well was measured.
