"ripple effect" on download of binary image #33

Open soxofaan opened 4 years ago

soxofaan commented 4 years ago

when downloading a binary (mask) image, the result has a strange ripple effect along horizontal dimension.

example: top image shows a scene classification layer, bottom image is binary mask by picking class 2: Screenshot from 2019-12-10 14-21-30

Thing is that the result is correct when you actually apply the mask. So I'm thinking that this occurs when we stitch the data into a geotiff. Binary data is a bit of a special case, so that might be the problem.
