Once your geophysical survey is under way Nordic Geoscience will represent your interests with a comprehensive survey data quality assurance and quality control (QA/QC) program.
Before survey commencement Nordic Geoscience sets up reporting procedures and documentation with the airborne survey provider and in cooperation with the airborne survey provider selects locations for any repeat survey lines and for figure-of merit manoeuvre tests.
Nordic Geoscience reviews the results of pre-survey aircraft tests and calibrations, including heading error tests, lag test, figure-of merit manoeuvre tests, altimeter calibration, repeat-line tests and any additional instrument tests and calibrations.
Nordic Geoscience requests the necessary improvements should the results of any of the test fail to meet specifications and review new test results, after which the aircraft is released for the first production flight.
After the first production flight Nordic Geoscience inspects the data for compliance with the survey contract specifications, and reviews any problems with the contactor for mitigation.
Once the aircraft is released for general surveying Nordic Geoscience typically monitors the survey data quality remotely through regular dispatches of data over the internet.
Data monitoring includes inspection of base station and survey data for compliance for data noise, aircraft turbulence, flight path and ground clearance deviations, flight speed deviations, flight line separation, GPS quality, sample spacing, missing data, diurnal drift, accuracy of flight logs, control line closure error, and repeat line error.
