Hi Kim, You should expect that the simulated categorical maps are less smooth than the maps of probabilities of occurrence generated by indicator kriging. Nevertheless, the simulated maps should honor the data at sampled locations. You might be doing something wrong, but hard to tell until we have a look at the parameter file.

Gordon Sent: Wed 9/13/2006 2:46 PM To: [email protected] Subject: AI-GEOSTATS: Categorical Indicator Simulation with Random Results Hello to all! I'm having some difficulty with indicator simulation with GSLib's SISIM. I have three categorical variables (based on rock type) that I have kriged to a grid using IK3D. The variograms for the data are surprisingly well behaved considering that this is "real" data. The kriged results honor the data and show a relatively stratified system (what I expected...). However, when I plug the same input into SISIM, I get seemingly random results and the data is not honored for all of the multiple realizations. I'm not using soft data or Markov chains...What am I doing wrong? Any suggestions are greatly appreciated!
