Finding the number of occurrences from an input list meeting a specified criterion

Available with Spatial Analyst license.

Three local tools assign the number of times a cell's values meet a specified criterion relative to the input values: Equal To Frequency, Greater Than Frequency, and Less Than Frequency. These tools determine for each cell how many times the input values obtained from a list of rasters are either equal to, greater than, or less than the specified value input.

To have the specified value be a single number, you can use the Create Constant Raster tool to create a constant raster of that value.


For example, for a particular cell location, consider a Value raster value of 2 and the following values:









Example input values

The sorted list of the input cell values is 0, 1, 2, 3, 5, 6.

The output from these tools would be as follows:

  • Equal To Frequency—Since there is only a single input value in the list that is equal to the Value raster, the output cell value is 1.
  • Greater Than Frequency—Three input values are greater than the comparison value of 2, so the output cell value is 3.
  • Less Than Frequency—Two values are less than the comparison value, so the output cell value is 2.
