DESCRIPTION

t.rast.null manages NULL-values of the input space time raster dataset.

The setnull parameter is used to specify values in the ranges to be set to NULL. A range is either a single value (e.g., 5.3), or a pair of values (e.g., 4.76-34.56). Existing NULL-values are left NULL, unless the null argument is requested.

The null parameter eliminates the NULL value and replaces it with the given value. This argument is applied only to existing NULL values, and not to the NULLs created by the setnull argument.

EXAMPLES

Set specific values (0,-1 and -2) of a space time raster dataset to NULL: 
    t.rast.null input=MY_INPUT_DATASET setnull=0,-1,-2
