Corrections for Earth curvature and atmospheric refraction

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,
