Thanks Fabrice,

I will certainly try mbtiles.

Hello
I'm also disapointed with gptk raster : too slow, not easy to prepare
For QField, we rather use .mbtiles format, created from QGis and the QTiles extension.
All formats that QGis uses can be converted in .mbtiles, it's very very easy to prepare.
QField uses .mbtiles raster very well, it's fast to display
Tested with a 4Go .mbtiles

Thanks Andreas,

Creating a Geotiff with pyramids did the trick. The only disadvantage is that it created a file of about 1.7 GB (the original was 90 MB).
Now I am ready to test the app ☺.

Hi Reginald,

Did you create pyramids in the gpkg rasters?

Generally, Geotiff should be well supported - definitely more tested than gpkg rasters. I had a 1GB geotiff on qfield (on SD-Card) and it displays fast. I haven't tested vrt files with geotiffs - if it works as well?

Hi Erwan,

You can look in the list of last week where I posted a couple of questions about qfield and was pointed to the right website for documentation.
I succeeded to publish a map on my phone but the aereal photo which was published as a gpkg file doesn’t render. When I use the raster.gpkg on my desktop it renders but very slow.
The gpkg file was created from a 90 MB jp2 file.

Regards,
