GPS Flagged

gpsFlagged on a FieldMeasurement is an automatic quality check. When the system computes gpsDistanceM and finds it beyond the allowed distance from the registered well, it sets gpsFlagged to true. Data managers review all flagged FieldMeasurements before finalizing field reports — a flagged record may indicate the wrong well was measured, the GPS had poor reception (check gpsAccuracyM), or the well's known coordinates need correction.
