Aceproject,
You need to give more information. You say 'not accurate'. Is it out by centimetres? metres? kilometres? wrong continent / mid-ocean?     Is it 'wrong' in all directions? or is it just too high or too low?  How is your model referenced? Did you use GCPs?

Hello aceproject,

I agree with Dave, some additional information would be helpful. Maybe you can provide the screenshot from the Google Earth that demonstrates the inaccurate positioning? Also the processing report from the project can give some insight on the issue.

thanks for the quick response admin.. Im using DJI Ground Station Pro to do the mapping.. as for my workflow.. I just import the folder where my image from DJI - align photos - build dense. I noticed the generated data is kinda distorted. I will upload photos.. thanks.

I didn't use GCP and let the DJI Ground Station Pro geotag data to process it. Did I miss something? is there a workaround? please help im still a newbie.. thanks for understanding.

You will need to use the optimization tool to refine the camera calibration parameters. As currently there are significant lens distortions which affect your products.

Is that camera considered a fisheye camera?  If so, would need to select that in camera calibration for camera type.
