r.null to have "more than" and "less than" flags #129

Open landam opened 5 years ago

landam commented 5 years ago

Reported by ychemin on 30 Jul 2014 10:19 UTC 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.

Comment by wenzeslaus on 30 Jul 2014 13:29 UTC http://grass.osgeo.org/grass70/manuals/r.null.html 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".
