Welcome to the ArcGIS Geostatistical Analyst extension for advanced surface modeling using deterministic and geostatistical methods. Geostatistical Analyst extends ArcMap by adding an advanced toolbar containing tools for exploratory spatial data analysis and a geostatistical wizard to lead you through the process of creating a statistically valid surface. New surfaces generated with Geostatistical Analyst can subsequently be used in geographic information system (GIS) models and in visualization using other ArcGIS extensions such as ArcGIS Spatial Analyst and ArcGIS 3D Analyst.
Geostatistical Analyst bridges the gap between geostatistics and GIS. Geostatistical tools have been available for some time, but never integrated tightly within GIS modeling environments. Integration is important because GIS professionals can begin to quantify the quality of their surface models by measuring the statistical errors of predicted surfaces.
Surface fitting using Geostatistical Analyst involves three key steps:
- Exploratory spatial data analysis
- Structural analysis (calculation and modeling of the surface properties of nearby locations)
- Surface prediction and assessment of results
Geostatistical Analyst contains a series of easy-to-use tools and a comprehensive wizard that guides you through each of these steps. It also includes a number of unique tools for statistical spatial data analysis.
