Splitting large MB Tile?

[Franziska]

Hi,

I created a large MB Tile with close up sat imagery of the Spanish north coast.
While this worked fine under OpenCPN when running Windows 10, it crashes under Windows 11.

It is not a question of computer power, I am running this on a PC with 64GB of Ram and a GTX 2070 graphics card.

Dave looked already into it and it's on Flyscreen as well. Still he had an issue handling this large MBtile on his computer.
I was not aware that a large MBtile would pose an issue.

So now I would like to split this huge MBtile into smaller chunks, but without having to recreate it in SASplanet.
It took quite some time to create it initially.

Does anyone know a piece of free software and procedure how I can do this, while maintaining the geo reference for the individual chunks?

Thanks for your help.

Thank you.

Found that one already but did not manage to get it to work.

Nevermind, luckily the SAS planet cache was still around and I managed to rewrite smaller MB tiles after all.
