DSM results from WebODM are not correct

Hi,
I am new to WebODM and I am trying to generate DSM and Orthomosaic images using default settings in WebODM.
The Orthomosaic image is correct by providing GCP but the DSM file is having inaccurate elevations when compared to google earth.
I am not sure what went wrong or is there any way/configurations in WebODM to have a better DSM generated.
Thanks!

If possible please provide a link to your dataset and specify the options that you used. I’ve always found DSMs to be accurate.

If you have GCPs, how does the DSM values compare to the elevation values specified in the GCPs?

I wouldn’t trust Google Earth as a ground truth.
