[Qgis-user] Help please !!

Hello Manon.

If I understand your issue, you are clipping a digital terrain model and 
the resulting raster is very course.  If you use the 
'Raster>Extraction>Clip Raster by Mask Layer' tool, you can define the 
resolution of the clipped raster. You can select 'Keep resolution of 
input raster' or define it in the x and y direction.  (see screen shot 
below).
