[GRASS-user] How to generate a random DEM Model of given size & resolution

[BHARATH RAM]

Hello,

I want to generate a set of random DEMs ( epsg code known to me). I am
aware that I need to use r.surf.fractal and specify fractal dimension.

But how do I specify other parameters of the raster map (like length &
breadth, resolution?)

Also, can you guide me towards how generate a set of many such maps using
scripting?

Also, are there any tips for me to follow so as to make this (DEM raster
map) dataset generation as fast as possible?

I am a beginner to Grass (& a beginner to GIS software as well). So please
forgive me if the question is trivial.

Regards,
Bsr
