<div dir="ltr">Hi guys<div class="gmail_quote"><div dir="ltr"><div><br></div><div>I am trying to fix artifacts that the gdaladdo is creating in the overview I am working on.</div><div><br></div><div>The gdal version I am working with is 2.3.2 <br></div><div><br></div><div>In general I have a big vrt file (RGB) on top of COGs with internal masks. There are places in the original rasters that we mask the values. <br><div><br></div></div><div><br></div><div>But when building overviews it seems like that the masked values in some layers are used, and artifacts are being created. <br></div><div><br></div><div>I was trying to play with many variant to understand these artifacts creation, the only variant I noticed to have an impact is the INTERLEAVE of the overviews,</div><div><br></div><div>When I set it to PIXEL it runs fast but creates artifacts</div><div>When I set it to BAND it runs 3 times longer and there are less artifacts created.</div><div><br></div><div>So far my understanding of the INTERLEAVE configuration was that it affects the final products block arrangement, I don't understand why it affects the product values, and the processing time as well<br></div><div><br></div><div><br></div><div>I hope that I am clear enough <br></div><div><br></div><div>Thanks <br></div><div><br></div><div><br></div><div><br></div></div>
