random fields generator

Hi everybody,

I have a problem and don't know if a solution exist: I have to generate a random field with assigned statistics; my generator uses a gaussian distribution and I need a log-normal distribution. While I can assign a proper mean and variance in order to get the desired statistics after the log transformation I can't figure out what to impose as spatial correlation scale in order to get the desired spatial correlation after the log transform. Any idea? thanks, lpn.
