Hello.

Are corrections for Earth curvature and atmospheric refraction calculated in Pix4DMapper?

Best regards

Hello Anastasiia,

These corrections are not calculated in Pix4Dmapper because an area covered by a drone is small enough for these errors to be negligible. If you want to cover a bigger area for which these corrections make sense, you should apply them to the GCPs (depending on the method you use to measure them); the software reconstructs the model based on the content of the images, and therefore these corrections do not apply for the reconstruction.

Best regards,
