Description
Class Summary  

CreateSpatiallyBalancedPoints  The Create Spatially Balanced Points tool is contained in the Geostatistical Analyst Tools tool box. 
CrossValidation  Removes one data location and then predicts the associated data using the data at the rest of the locations. 
DensifySamplingNetwork  Uses The Densify Sampling Network tool is contained in the Geostatistical Analyst Tools tool box. 
DiffusionInterpolationWithBarriers  Uses a kernel that is based upon the heat equation and allows one to use a combination of raster and feature datasets to act as a barrier. 
ExtractValuesToTable  Extracts cell values from a set of rasters to a table, based on a point or polygon feature class. 
GACalculateZValue  The Calculate Zvalue tool is contained in the Geostatistical Analyst Tools tool box. 
GACreateGeostatisticalLayer  Creates a new geostatistical layer. 
GAGetModelParameter  Gets model parameter value from an existing geostatistical model source. 
GALayerToContour  Creates a feature class of coutours from a geostatiscal analysis layer. 
GALayerToGrid  Exports a Geostatistical layer to a raster. 
GALayerToPoints  Exports a geostatistical layer to points. 
GAMovingWindowKriging  Recalculates the Range, Nugget, and Partial Sill semivariogram parameters based on a smaller neighborhood, moving through all location points. 
GANeighborhoodSelection  Creates a layer of points based on a userdefined neighborhood. 
GASemivariogramSensitivity  Performs a sensitivity analysis with varying Nugget, Partial Sill, and Range values. 
GASetModelParameter  Sets parameter value(s) in an existing geostatistical model source. 
GaussianGeostatisticalSimulations  Performs a conditional or unconditional geostatistical simulation based on a Simple Kriging model. 
GlobalPolynomialInterpolation  Fits a smooth surface that is defined by a mathematical function (a polynomial) to the input sample points. 
IDW  The IDW tool is contained in the Geostatistical Analyst Tools tool box. 
KernelInterpolationWithBarriers  A moving window predictor that uses the shortest distance between points so that points on either side of the line barriers are connected. 
LocalPolynomialInterpolation  Fits the specified order (zero, first, second, third, and so on) polynomial, each within specified overlapping neighborhoods, to produce an output surface. 
RadialBasisFunctions  The Radial Basis Functions tool is contained in the Geostatistical Analyst Tools tool box. 
SubsetFeatures  Divides the original dataset into two parts: one part to be used to model the spatial structure and produce a surface, the other to be used to compare and validate the output surface. 
With Geostatistical Analyst, you can easily create a continuous surface, or map, from measured sample points stored in a pointâ€“feature layer, raster layer, or by using polygon centroids. The sample points may be measurements such as elevation, depth to the water table, or levels of pollution. When used in conjunction with ArcMap, Geostatistical Analyst provides a comprehensive set of tools for creating surfaces that can be used to visualize, analyze, and understand spatial phenomena.
Geostatistical Analyst contains tools for exploratory spatial data analysis and a geostatistical wizard to lead you through the process of creating a statistically valid surface. Surface fitting using Geostatistical Analyst involves the following key items:
Exploratory spatial data analysis Structural analysis (calculation and modeling of the surface properties of nearby locations) Surface prediction and assessment of results
New surfaces generated with Geostatistical Analyst can subsequently be used in geographic information system (GIS) models and in visualization using ArcGIS extensions, such as ArcGIS Spatial Analyst and ArcGIS 3D Analyst. The tool contained in the Geostatistical Analyst toolbox converts a layer created with the Geostatistical Analyst extension to a grid so that it can be used in subsequent analyses.
