Package PluriDemo

The PluriDemo package has been designed to allow users to discover plurigaussian simulations by “playing” with them. They make possible to visualize simple plurigaussian simulations and to see how changes in the input parameters affect the resulting images.

The following demonstration programs can be downloaded:

  • PluriDemoSimu: It makes it possible to visualize plurigaussian simulations and to see how changes in the input parameters affect the resulting images.It illustrates the images that can be obtained by combining already prepared images (of the two underlying gaussian random functions) and playing with different truncation schemes and the proportions of each facies
    (More information...) or (Exercises...)
  • PluriDemoVario: It illustrates the relationship between the indicator variogram and those of the underlying gaussian random functions (RFs for short) that are truncated to give the indicators.It shows the variograms of the indicators that can be derived from the structures of the underlying gaussian random function, using different truncation schemes and various proportions
    (More information...) or (Exercises...)
  • PluriDemoSet: It highlights the use of this model in the case of a random set. It illustrates the type of random set that can be obtained by combining already prepared images (of the two underlying gaussian random functions) with variable proportions.
    (More information...) or (Exercises...)

For each program we provide a set of graded exercises showing how to run the program and how the key parameters affect the simulated images or the indicator variograms, as the case may be.

These three programs can be downloaded from the following sites:
