Hi Selvakumar,

It would be great if you write a support&nbsp;ticket to us since we would need more information about the project such as the quality report, p4d file, and the log file.&nbsp;

Hi Sevalkumar,

The quality report you sent looks good. Can you send a screenshot and mark the position where you think there is distortion? Also, send us your orthomosaic (the tif file) so that we can overlay it in a map and create some transparency to look at the distortion closely.

Hi Sevalkumar,

I would recommend you to use rolling shutter correction for this project. You can read more about it here; [https://community.pix4d.com/t/3555-Phantom-4-Pro-Rolling-shutter-effect](https://community.pix4d.com/t/3555-Phantom-4-Pro-Rolling-shutter-effect) and [https://support.pix4d.com/hc/en-us/articles/208460436-How-to-correct-for-the-Rolling-Shutter-Effect](https://support.pix4d.com/hc/en-us/articles/208460436-How-to-correct-for-the-Rolling-Shutter-Effect)
