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.

## Example

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

ValRas | InRas1 | InRas2 | InRas3 | InRas4 | InRas5 | InRas6 |
---|---|---|---|---|---|---|

2 | 3 | 6 | 1 | 2 | 0 | 5 |

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.
