Bad calibration.

Sensor-shift or lens shift IS enabled?

Hello geochina,

In case of such aligning results of aerial data we recommend to optimize the photo alignment using camera coordinates (if any) with the corresponding Camera Accuracy parameter in the Ground Control settings.
Some times several optimizations is required to fix such "bowl-effect".

Geochina good afternoon. Could you correct the problem  of the bowl effect? We have a similar problem with a strip of 30 kilometers. Regards
