We are sorry to hear you are not happy with your results.
From the Data Collection guidelines:
Job Shape - When doing long, linear jobs, make sure to do AT LEAST three passes so there are enough perspectives to reconstruct the scene. Increased overlap will need to be used to make up for the lost width. When doing few passes don't do a straight line. Either put a kink in it or use more passes.
Aside from having three passes, using 85% or more overlap is needed to get the system enough looks at everything. 80% overlap corresponds to 25 views when more passes are present. Where there are only 3 it gives 15 looks. 85% overlap would give the system 21 looks at everything with 3 passes. This value will give you a better chance of things trying out well.
The camera on the Mavic 2 Zoom isn’t the best for mapping so if you plan on doing lots of work like this you might want to look into upgrading your aircraft.
