.SH NAME
\fI\fBr.surf.gauss\fR\fR  - GRASS module to produce a raster map layer of gaussian deviates whose mean and standard deviation can be expressed by the user. It uses a gaussian random number generator.

.SH DESCRIPTION
\fBr.surf.gauss\fR produces a raster map layer of Gaussian deviates whose
mean and standard deviation can be expressed by the user. It uses a Gaussian
random number generator. It is essentialy the same as \fIr.surf.random\fR,
but uses a Gaussian random number generator instead.
