@platinum_surveys Agreed, but…
When working with technologies like PPK, depending on the circumstance, the concept of ‘ground control’ or ‘ground validation’ isn’t completely irrelevant.
Depending on the size of the site, some ground validation may need to be in place. This allows the survey drone to continue producing a very high level. You’re still saving an incredible amount of time when working with PPK and ground validation as opposed to working with GCPs. You may need to lay just 3 ground validation points on the entire job site as opposed to 10 GCPs. Consider it a housekeeping task that ensures super precise data.
Another situation in which GCPs carry on applicability is when defending data. Since drone mapping is still a relatively new concept, many contractors want to see its precision and accuracy. GCPs allow the survey drone to produce a very defensible quality report and really prove the validity of the solution.
@Christina, Does DroneDeploy even support PPK imagery?
