I have problem with aerial dataset, when i import photos of 1400 meters length road and start AT, it becomes curved. I tried this solution <a href="/products/3d_imaging_and_point_cloud_software/w/wiki/28536/the-model-appears-to-be-curved-instead-of-being-horizontal-after-at">https://communities.bentley.com/products/3d_imaging_and_point_cloud_software/w/wiki/28536/the-model-appears-to-be-curved-instead-of-being-horizontal-after-at</a> , AT is now correct but the final Orthophoto production&#39;s accuracy was not satisfactory. How can I improve it? Can it be related to&nbsp; wrong imported optical properties e.g. from diffrent project but with the same camera?</p><div style="clear:both;"></div>
