Description (last modified by )
GDAL 2.2.2, released 2017/09/15
When generating tiles for a specific zoom, sometimes all the tiles in one of the directories (X-coordinate) appear to be blank (have no data, all the pixels are hidden by the alpha band).
Repro
- Download the attached xxx.tif file
- Generate tiles for zoom level 20:
gdal2tiles.py xxx.tif -z 20 - Check files in
xxx/20/183366directory
Actual results
All the files generated are blank. There is no actual data, all the pixels are hidden by the alpha layer.
Expected results
There shouldn't be "xxx/20/183366" directory created at all, I guess, and no tiles generated there.
