- Reclassify: replace values with a new value
- Single value: all occurences with the desired value will be
reclassified to the selected new value; this should be done with
integer and not floating point grids (use range for that)
- Range to single value: values between a desired min and max will
get the desired new value
- All valid to single value: anything that is not missing data
will be converted to the desired new value.
- +Inf: converts anything coded as positive infinity will be
converted to desired new value; missing data will not be affected.
- NAN: converts anything coded as "not a number" will be converted
to desired new value; missing data will not be affected.
- +/0/- codes: select a tolerance around zero, and all values
will be coded as -1 or 0 or 1.
- From lookup table; only works with an integer grid with no
more than 256 distinct values. You must create a database
with "OLD_CODE" and "NEW_CODE" fields, and that will be used as
a look up table for reclasification.
- Replace all possible values from second grid: every valid value in the second,
already opened grid will replace the nearest grid posting in the
grid being edited.
- Replace only valid values from second grid:
- Remove: set a threshold. If a single point is this much,
or more, higher or lower than all eight neighbors, it will be
replaced with the average of those eight points.
