hello, as you can see, in the reconstruction of the multispectral 2D map, there are strips with the form of a nosy repeated in all but on RGB and NDVI. What could this deformation be due to? exhibition, planned with GS PRO and processed with DJI TERRA.
In addition, once the remote control is connected via cable to the PC and installed the drivers, and the ground software does not recognize the system.
  Using GS pro instead tells me that the camera is not compatible for processing and transmitting images. I look forward to your kind feedback, a good day and a good job as soon as possible

Thank you for your patience, when the Solar elevation angle is low, the change of the aircraft attitude will cause the measurement of solar light intensity fluctuate greatly. DJI Terra implements the light compensation at the aircraft end. In different flight scenarios, the data obtained is inconsistent. It is recommended that you collect multispectral data when the  Solar elevation angle is large.
This phenomenon can be alleviated by the following methods:
1. Please update GS Pro to v2.0.9. The app will give priority to setting the heading direction of the aircraft perpendicular to the sun's position to optimize this problem.
2. It is recommended collect data when the Solar elevation angle at noon is relatively large or in cloudy days, which will be more accurate.
