The problem doesn' t come from Reefmaster. I have tried MBtiles files to export from SAS planet to Global Mapper and it doesn't work...

I search a reason !!

Hi,

I can confirm GlobalMapper 18.1 is loading ReefMaster MB Tiles like it should. No problems, no pop-ups asking questions.

I don't understand why at home it doesn' t work, neither with Reefmaster neither with SAS planet.

Thanks for your test

Danny, what an import setting you have used?
Have you test it with an aerial photo as background (correct position)?

Since RM 1.0 ou RM 2.0 ?

Is it possible to send for me your Mbtiles ? i would like make an essai

I did'nt adjust anything. Only 'Open Dafa file' .
I did check with an aerial background map. All was in the right position.

This is just a small file for testing.
It is working for me in GM 18.1

Thanks for your MBTiles file.
But i have a problem with my French version.I will contact the French distributor.

I had to have a bug in my version French Global Mapper.

I did an uninstall and reinstall GM and everything is ok. No errors, no messages, is good.

The import option in GM v18.1 is "MapBox MBTiles Tileset files".

But
- the image quality is much worse than in RM or other apps with MBTiles options and
- GM only display one zoom level, even if the present MBTiles file contain more than one zoom levels.

I haven' t done much testing yet but here is an image made since RM 2 and exported to MBtiles then opened in GM 18.1. I find the quality correct.
On the right I can see the carp bench.
Certainly it starts to pixelize a little but normal in view of the zoom.

Look e. g. to the depth lines and you see, what i mean. For a vector element is this bad quality. There is a much better view from this element in RM or phone apps.

Have you find more than one zoom levels - i not.
