A few times a strange phenomenon of repetitive tiles appear for one zoom level. The example GeoTiff consist of 3 overviews-pyramids: Base: 32918x51348 Overview1: 10973x17116 Overview2: 3658x5706 Overview3: 1220x1902 Which can be expressed as resolutions (m/pixel) Resolution: 1.34909836065574,0.449945325314379,0.149995443360977,0.05 If we use resolutions: … 0.44995, *0.29999* ,0.15 … we get the strange result if we change to: … 0.44995, *0.3,0.2* ,0.15 … it disapears. Perhaps this is known bug and bad practice to align the resolutions to the internal overviews, otherwise it is just strange.
