We have provided notes in the GC Notes section a few times.
Per 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.
You are doing straight single pass missions. Straight and single pass are the problem here. Make it not straight and do the 3 passes that are recommend and you will get reliable results.
