Equal to Frequency, Greater than Frequency, Less than Frequency
Equal to Frequency, Greater than Frequency and Less than Frequency respectively calculates the number the values in a set of input rasters are equal to, greater than and less than another value raster or input value.
The value can be a constant. Besides, if a cell location has NoData on any one of the input rasters, that location will be assigned NoData on the output.
See the figure below:
1.The value raster is 3.
2.The cells at upper left corner of the input rasters are respectively 1(IR1), 1(IR2) and 3(IR3). In this cell location, the value equal to 3 for 1 time (Equal), greater than 3 for 0 time(Great) and smaller than 3 for 2 times (Less).
3.If any one input cell has value NoData, that location will be assigned NoData on the output.
