SAGA.grid_filter.1: Gaussian Filter

The Gaussian filter is a smoothing operator that is used to 'blur' or 'soften' data and to remove detail and noise. The degree of smoothing is determined by the standard deviation. For higher standard deviations you need to use a larger search radius.

Inputs

Grid

Please set a value for INPUT.

The standard deviation as percentage of the kernel radius, determines the degree of smoothing.

number

The shape of the filter kernel.

string

The kernel radius in cells.
