#2383 new enhancement

r.null to have "more than" and "less than" flags

Reported by: ychemin Owned by: grass-dev@…
Priority: normal Milestone: 7.6.2
Component: Default Version: unspecified
Keywords: Cc:
CPU: Unspecified Platform: Unspecified

Description

In many imagery dataset, it is common to need to slice off a large (or small) value and any other value above (or below) into NODATA/NULL values.

r.null could be extended to perform this operation.

Flag would transform setnull option value into the lower boundary (if "more than" flag) or upper boundary (if "less than" flag) threshold to make null values.

r.null manual claims to support syntax setnull=56-89.

Some other modules supports value=56- (and value=-56?) which might be the proper syntax for your request. If it is not already supported and if there is some solution for value=-56 in meaning "from -inf to +56" versus "only value -56".
