Hi Ondrej, thank you for your answer!
To summarize, the process consists on, once made sure that the coordinate system is in epsg:4326 - GPS (WGS 84), go to scene 3d → tools → Ortho projection → render, and then Ortho 2d → Export → Ortho projection and export a .tiff file.
Would all the information that I mentioned in the first message included there?
Thank you!
