Orthomosaic artefacts/patterns in River mapping


Do any of you guys and gals experienced this horizontal pattern that is seen in the orthomosaic?

I’ve mapped bodies of water before like coastal areas, creeks, ponds but I’ve never seen this horizontal pattern on the water.

I’m thinking there might be something wrong with my drone. Hoping I can get some reference from this community. It would be a great help.


I have here a screendump of my orthomosaic for you to see what im talking about.




Hi Ryan,

The pattern you see in your orthomosaic is due to difference in light exposure between some of your images.
Unfortunately there is not much you can do right now in order to correct such behavior.
For future image acquisition, we recommend you to fly under constant sunlight.
Nevertheless, maybe you can improve your results using the mosaic editor:


Thanks for the reply Marco. Appreciate it.

I thought it was caused by some defect in my drone.

This is the first time I encountered this issue.

Even surveying in coastal areas before the orthomosaic results were all good.

Thanks again Marco. I’ll try to see if there’s hope with editing the Orthomosaic.
