Even with GPU the processing takes too long

I'm using metashape command line tool on g4ad.4xlarge in AWS. 

Every step is fast but build DEM is really slow.

This all takes too long than expected.

Hello aniket,

Can you please share complete log related to BuildDEM operation and also specify Metashape version number that you are using?

I'm using GRID drivers with in this one. Does agisoft support GRID drivers?

Hello aniket,

According to the provided log, GPU is utilized properly at steps, where GPU-support is available.

However, the expected resolution of DEM to be generated: 19056986x23013039 seems incorrect to me. It could be a result of incorrect georeferencing or wrong coordinate system selection. If you open the project saved before Build DEM task is run, do you see that the model is georeferenced correctly? If not, you may need to adjust to script in order to apply proper coordinates and select coordinate system.
