Finally, the pilot will check the results for accuracy and quality. This usually involves comparing a subset of coordinates from the processed drone data with the same points measured independently with the GNSS receiver (commonly referred to as check points). 

• If the results are within the required tolerances, the scan can be considered complete. If not, some troubleshooting and potentially additional data collection might be needed.

This process enables the team to acquire highly accurate and precise spatial data from a drone scan, which can be used for a wide variety of applications in GIS, construction, and other fields.

After completing the drone flight, the pilot will transfer the images and the RTK/PPK data to a computer and more specifically, the pre-determined photogrammetry software for the project. Having ensured the GCPs are properly identified and utilized to georeference the data, the software will generate a point cloud, digital surface model, or other deliverables as required by the project.

Executing the flight plan, the drone pilot will ensure the drone maintains a consistent altitude and speed, and overlaps images sufficiently to allow for accurate photogrammetric processing (typically around 75-90% forward overlap and 65-85% side overlap). All the while, monitoring the drone's status and the data collection process throughout the flight.

Now, setting up the drone, the team will ensure that the RTK (Real-Time  Kinematic) or PPK (Post-Processed Kinematic) system and the camera ,or other sensors, are correctly configured. If using an RTK system, the trained pilot will ensure the base station is properly set up and that there is good communication between the base station and the drone.

Using a GNSS receiver, the certified team member will scan in each GCP. Record the precise coordinates of each GCP, ensures that the GNSS receiver has a clear view of the sky and has collected an adequate amount of data for each point.

The Drone Pros team will arrive On-Site and place highly visible GCPs throughout the site. These are known locations that are scanned in using a high-accuracy GNSS receiver. They serve as reference points to accurately georeference the drone data. The number and distribution of GCPs will depend on the size and complexity of the site, but they should be evenly distributed and visible from the air.

First, the Drone Pros will need to understand the project's needs and specifications. This includes the site's size, the level of accuracy required, and any obstacles that might pose a safety risk or affect data quality. From this information, the team can develop a flight plan. While also checking local regulations and ensure all permissions and permits are in place.
