How to generate XYZ tiles using QGIS3

Overview

QGIS3 has a tool called 'gdal2tiles.py' which can generate map tiles, but currently, it only supports TMS, not XYZ. However, QGIS3 loads XYZ by default and requires checkbox for TMS, so it's better to convert TMS to XYZ.

The difference between TMS and XYZ is just the name of Y-coordinate, so renaming works well. tms2xyz.py is a script for that.

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

Disk Utility is unable to repair this at first, but the fix is this:

Use diskutil list to find the right drive id.
You want the id under the IDENTIFIER column, it should look like disk1s1
Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
-d is debug so you'll see all your files output as they're processed.
Answer YES if it gives you the prompt Main boot region needs to be updated. Yes/No?
