    The sophistication of UAVs does not mean one can disregard the quality control it. In order to gain quality data and results, quality checks must be put into place.

    Checks can be found in 3 divisions; Project Plan checks, Standard checks and UAV specific checks. In terms of Project Plan checks, quality measures should be made before proceeding to on-site work. This is to make sure that there are no errors in the flight plan, settings are all in order and that there are no discrepancies in the ground control plan. One helpful program that could be used is Altizure. This application enables the drone to clearly report back the camera settings. By utilizing these software, the pilot will be able to confirm that the UAV is all set according to plan.

    In terms of Standard checks, these are procedural checks to ensure that the data collection process goes smoothly. Since flying conditions can be variable, the speedy change of flying heights set a challenge for pilots to capture pictures with 100% certainty. A check should also be performed to confirm that the all images captured are complete and uncorrupted. Consideration should also be placed on what seems as a low-priority task such as file naming. All these tasks collectively come together to create a smooth process, no matter the size of the task.

    Another check that is vital to the accuracy of the results is UAV specific checks. Once the images have been collected, it’s important to verify that the quality of the images itself are of standard, that is that the resolution, overlap and the alignment of the imagery have no errors. Once the images are deemed as reliable and accurate, they will be fit for use.

    In order to achieve minimal error in the output models, quality control should be implemented in various stages of the process. Quality checks must be in place from the very start of the process
