. Sometimes the chunk must
be aligned with a raster, for example to ensure the continuity of the output. If the chunk size is
800 and the expected product is a raster with a resolution of 35, 800 and 35 are not compatible
and will create 2 different partial pixels on the edges. The realignment option forces the
chunk to fit the grid alignment.
