When I use this approach to generate a GeoTIFF, I have to add a correction in the y-direction using the TileY xml element, otherwise gdal tries to retrieve the incorrect tiles and generates a blank image.

In the case of zoom level 12, it requires this correction:


The curious thing is that the correction changes depending on zoom level.


12 zoom requires -360 correction.

11 zoom requires -180 correction.

10 zoom requires -90 correction.

So there's a clear pattern. Could someone help me understand what may be causing the issue?

I tried setting the ESPG code in the command and the xml file, but it didn't help.
