This tool can be used to a raster image filled with random values drawn from a standard normal distribution. The values range from approximately -4.0 to 4.0, with a mean of 0 and a standard deviation of 1.0. The dimensions and georeferencing of the output random field (output) are based on an existing, user-specified raster grid (base). Note that the output field will not possess any spatial autocorrelation. If spatially autocorrelated random fields are desired, the turning_bands_simulation tool is more appropriate, or alternatively, the fast_almost_gaussian_filter tool may be used to force spatial autocorrelation onto the distribution of the random_field tool.
