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 Fabrice 2016-09-23 11:20 GMT+02:00 F T <ouk...@gmail.com>: > 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 > > Fabrice > > 2016-09-22 9:32 GMT+02:00 Reginald Carlier <Reginald.Carlier@ > ingelmunster.be>: > >> Thanks Andreas, >> >> >> >> Creating a Geotiff with pyramids did the trick.
