The above screenshot shows the waterbody mask layer generated by logical expression, has significant offset with respect to underlying water body imagery as seen on Landsat 5 TIle (UTM projected imagery).
How can I overcome the anomaly?
please clarify which product was used to create the mask and which product is displayed in your screenshot
Landsat 5 TOA Radiance product with UTM projection
I’ve just tried the same mask expression on two products and it works.
I wonder where the green and the blue mask are coming from? They are not shown in the mask manager.
Have you done something else then just creating the mask?

Thanks @marpet, for verifying the product on your side.
I have enabled only red mask, and
there are no green and blue masks, they are the colors of image pixels themselves,
but displayed in “MERIS L1b-Tristimulus” RGB Profile/Channel combination.
I found out that the offset in the mask doesn’t happen, if the RGB Profile/Channel combination
is set to actual i.e., “Landsat-TM 3,2,1”.
