<p class="MsoNormal"><span style="font-size:12.0pt"
lang="EN-US">Hello everybody. I have an issue
regarding the Geopackage format. I have tried to
import a singleband raster file (it represents the
land cover, thus every pixel has a single integer
value corresponding to the land cover class), but
this operation seems to modify the raster
characteristics: the raster becomes a 4-bands raster
and the pixels values change accordingly (basically,
the original raster is saved in the Geopackage as an
RGB image). It seems to be a bug of QGIS. I have
also tried to use GDAL translate through the
processing toolbox of QGIS to convert the TIFF file
to a Geopackage file, but the result is the same.</span><o:p></o:p></p>
