You can use the statistics operators to evaluate raster statistics like variance, mean, standard deviation of grid files. The calculator statistics fuctions support band index also. Raster statistics functions work on single-band. To work on other bands of a field you need to open another instance of it.
| Function | Meaning | Example |
|---|---|---|
| Rmin(Rastern) | The minimum value of the Rastern | Rmin(Input_1) |
| Rmin(Rastern[band]) | The minimum value of Rastern, with optional zero-based band index in square brackets. | Rmin(Input_1[0]) |
| Rmax(Rastern) | The maximum value of the Rastern | Rmax(Input_1) |
| Rmax(Rastern[band]) | The minimum value of Rastern, with optional zero-based band index in square brackets. | Rmax(Input_1[0]) |
| Rmean(Rastern) | The mean or average of the value of the Rastern | Rmean(Input_1) |
| Rmean(Rastern[band]) | The mean of the values of Rastern, with optional zero-based band index in square brackets. | Rmean(Input_1[0]) |
| Rstddev(Rastern) | The standard deviation of the value of the Rastern | Rstddev(Input_1) |
| Rstddev(Rastern[band]) | The standard deviation of the values of Rastern, with optional zero-based band index in square brackets. | Rstddev(Input_1[0]) |
| Rvariance(Rastern) | The variance of the value of the Rastern | Rvariance(Input_1) |
| Rvariance(Rastern[band]) | The variance of all values of Rastern, with optional zero-based band index in square brackets. | Rvariance(Input_1[0]) |
