What's New in 9.3.1
Take a look at the new features and tools you can use with ArcGIS Desktop 9.3.1.
Simulate
Interpolation methods produce one value for every location. In reality, there are many, equally probable values that could occur at each unsampled location (the true value for each unsampled location is unknown). Geostatistical simulation produces multiple surfaces that mimic the real phenomenon and provide these possible values, giving a basis for risk analyses, economic decision making, and other estimations involving uncertainty, allowing analysts to make more informed decisions.
- Conditional Simulation
- Unconditional Simulation
- Postprocessing (clipping, summary statistics for cells and for polygonal areas of interest)
