Description

Not sure if this is still true, but the manual page for i.smap says:

The module i.smap does not support MASKed or NULL cells. Therefore it might be necessary to create a copy of the classification results using e.g. r.mapcalc.

It would be nice to know if this is still the case.

This still is a case.

To make things worse – if NULL cells are inside a block, result differs significantly from a different sized block without NULL cells. Thus maps with NULL values should use as small blocks as possible.
