Many Thanks, But I guess explained very badly (sorry for this!!) what I need. I am building an Agent Based Simulation and part of the model requires series of two randomly generated raster maps, having a spatial cross- correlation index ranging from -1 to +1. Clearly If I can specify autocorrelation of each that will be even better, but at this stage I just need two randomly generated surfaces with a user-specified Cross- Correlation Index. Sorry again for the bad explanation!
