Note on manned aircraft data:
The AirWorks application is also suitable for datasets collected with manned aircraft, with some limitations depending on the GSD and altitude of the data collected. To learn more about processing manned aircraft data in the AirWorks app, click here.

In order to maintain the highest standards of accuracy in our deliverables, we request that if you have data that has been collected outside of our recommended parameters, you either collect the data again or speak to someone from our support team before submitting your data to discuss accuracy expectations and what we are able to deliver.

Please contact your account manager for details on data quality and accuracy.
