The SHAPE field of the mosaic dataset item contains invalid geometry. Incorrect segment orientation: individual segments are not consistently oriented. The "to" point of seg i should coincide with the "from" point of seg i+1.
Each segment on a line should have a consistent direction, which is dictated by the to and from attributes. The geometry needs to be updated to ensure correct segment orientation.
