In this episode, David teams up with licensed land surveyor and aerial mapping expert Michael Detwiler to break down how to assess the accuracy of your drone mapping projects—step by step.

Using real-world data from two WingtraOne Gen II drone flights (including a park survey and an orange grove redevelopment), they review:

-How to interpret accuracy reports from Wingtra and Pix4D
-What RMS error means in practice—and why it matters
-How many GCPs and checkpoints you really need
-Common pitfalls in ground control and image calibration
