Review Quality Assurance (QA) Flags

Review Quality Assurance (QA) Flags

IMDEXHUB-IQ™ has a number of rules built in to assist with reviewing and approving Survey Readings in the Approve Surveys module. Some of the QA settings are set and some are editable.

The QA Flags are warnings only. You are still able to Approve or Reject readings.

When a measurement fails one or more of the QA checks for a particular tool, that measurement and reading are highlighted.

Hovering your mouse pointer over the measurement displays the rule that has failed.

Note that altering the QA Settings might alter the QA flags, but does not affect the Approved/Rejected/Pending status of the readings.

The rules for the specific tools are:

TN14 QA Flags

None of the TN14 QA flags are editable by the user. The following flags are set within IMDEXHUB-IQ™:

Azimuth varies by more than ±0.5° of planned
Dip varies by more than ±0.5° of planned
Dip is within 5° of vertical (±90°)

EZ-GYRO QA Flags

Set QA Flags include:

Earth Rate Delta is 0.5 or greater

REFLEX EZ-GYRO™ data has the following editable QA Flag:

Target Tolerance

EZ-TRAC QA Flags

When you create a Drillhole in Plan Drillholes, the following rules apply:

If it has Latitude and Longitude, IMDEXHUB-IQ™ retrieves from the World Magnetic Model Coefficients the expected Magnetic Field and Magnetic Dip for that area
If the Drillhole does not have Latitude and Longitude, the Magnetic Field and Magnetic Dip are taken from the fields set against the Project
If the Drillhole has neither a. nor b., then the default is zero

The following EZ-TRAC QA Flags are set:

Gravity more than 2% variation from 1.0
Roll angle is within 2° of an adjacent reading within the same survey

EZ-TRAC has the following editable QA Flags:

Target Tolerance
Magnetic Field
Magnetic Field Range - default is 1000
Magneitc Dip
Magnetic Dip Range - default is 0.5
