Tear drops display in orthos

With the latest version of Pro, we are getting imperfections in the orthos that look like small bubbles or tear drops.

Using mosaic editor we can replace with Planar but then loose the spatial accuracy.

 

What is causing this ?

 

Hello Brian, 

An explanation would be that step 2. Point Cloud and Mesh was not processed. This would result in the Digital Surface Model (DSM) and thereby the orthomosaic being generated based on the Automatic Tie Points instead of the Densified Point Cloud. Therefore, it would use less information and could result in artifacts. 

Best regards
