GCP Elevation is not reflecting in point cloud and DSM

Hello all,

I’m facing an issue that I found there are some missing GCP in flight ( Removed before mission).
so I tried to mark the points manually as 3D GCP (without a fixed GCP ) so I can minimize the z error in these areas and to check how the result is close to conventional survey.
but the problem is that at these locations it is not reflecting the entered GCP elevation.

I did another processing without using missing GCP ( I deleted them) and it gives me the same DSM as with the manual one .

any idea what is the issue in manual marking of GCP ?

Hi,

Could you please send us the following?

▸ The quality report (.pdf format): …\project_name\1_initial\report\project_name_report.pdf
▸ The project log file (text file): …\project_name\project_name.log
▸ One or several screenshots of the issue.

In my understanding, you try to use GCPs that do not appear in the images. When you say you try to mark them manually as 3D GCPs, how exactly did you do that? What were the steps followed?

Best,

Please find the attached as requested.

The same process of marking GCP that they exist in site but without actual GCP.

Hi,

Thank you for sharing the file with me.

I had a look and the quality report looks very good.
Were you expecting different outputs?

Best,
