Available with Geostatistical Analyst license.
The ArcGIS Geostatistical Analyst provides the capability for surface modeling using deterministic and geostatistical methods. The tools it provides are fully integrated with the GIS modeling environments, and allow GIS professionals to generate interpolation models and assess their quality before using them in any further analysis. Surfaces (model output) can subsequently be used in models (both in the ModelBuilder and Python environments), visualized, and analyzed using other ArcGIS extensions, such as ArcGIS Spatial Analyst and ArcGIS 3D Analyst. The ArcGIS Geostatistical Analyst contains the Geostatistical Wizard and a set of geoprocessing tools that are specially designed to explore your data, create interpolated surfaces, and post-process the results.
