When I reproject an raster layer in CELL format using nearest neighbor
assignment, the resulting output map is in DCELL.

Comment(by neteler):

Did you use the bilinear or cubic convolution method? Then it is no
surprise.

To maintain CELL, you need to use the nearest neighbor method.

Comment(by pvanbosgeo):

That would indeed be no surprise :-).. But no, as mentioned in the
description, this is when using the nearest neighbor value, using an
integer map (CELL) as input.
