ArcGIS Pro: Mosaic dataset created with Frame Images (WGS 1984 UTM) has wrong orientation

We have two types of Ultracam frame stereo images:

  • For Switzerland with spatial reference "CH1903+ LV95" (xy), and "LN 1902" (z)
  • For Ukraine with spatial reference "WGS 1984 UTM Zone 34N" (xy), and "EGM 2008 Geoid" (z)

 

For both types of images, we used the same workflow:

  1. Used sup-files (SocetSet Support files) to extract data for Frame Table and camera file for Camera Table
  2. Used this workflow to create mosaic dataset: Create a mosaic dataset from aerial imagery for stereo mapping—ArcGIS Pro | ArcGIS Desktop 

 

We got the following results:

  • When sups of both Switzerland and Ukraine are loaded to Map, orientation is correct
  • When mosaic dataset of Switzerland is loaded to Map, orientation is correct
  • However, when mosaic dataset of Ukraine is loaded to Map, mosaic dataset is rotated by 90°

 

Does anyone have an idea why this happens? My guess is that it has something to do with the spatial reference.
