I'm trying to create python script that will batch create tiles from tiff file.
Using python gdal2tiles.py -s EPSG:4326 -z 11-17 -w none tif_4326.tif
I get folder with png files, but this pngs is not georeferenced. When I load tiles in QGIS for verification, they are displayed in a completely different place. What am I doing wrong? And units-per-pixel="76.43702827148438" from tilemapresource.xml looks too big, is this pixel value correct?
