The Interpolation toolset contains tools that predict values at unmeasured locations.

Tool | Description |
---|---|

Interpolates a surface using a kernel that is based upon the heat equation and allows one to use raster and feature barriers to redefine distances between input points. | |

EBK Regression Prediction is a geostatistical interpolation method that uses Empirical Bayesian Kriging with explanatory variable rasters that are known to affect the value of the data that you are interpolating. This approach combines kriging with regression analysis to make predictions that are more accurate than either regression or kriging can achieve on their own. | |

Empirical Bayesian kriging is an interpolation method that accounts for the error in estimating the underlying semivariogram through repeated simulations. | |

Interpolates 3D points using Empirical Bayesian Kriging methodology. All points must have x-, y-, and z-coordinates and a measured value to be interpolated. The output is a 3D geostatistical layer that calculates and renders itself as a 2D transect at a given elevation. The elevation of the layer can be changed using the range slider, and the layer will update to show the interpolated predictions for the new elevation. | |

Fits a smooth surface that is defined by a mathematical function (a polynomial) to the input sample points. | |

Uses the measured values surrounding the prediction location to predict a value for any unsampled location, based on the assumption that things that are close to one another are more alike than those that are farther apart. | |

Interpolates the values of 3D points using inverse distance weighting (IDW) and creates a voxel layer and source file (.nc) of the predicted values. | |

A moving window predictor that uses the shortest distance between points so that points on either side of the line barriers are connected. | |

Fits the specified order (zero, first, second, third, and so on) polynomial, each within specified overlapping neighborhoods, to produce an output surface. | |

Recalculates the Range, Nugget, and Partial Sill semivariogram parameters based on a smaller neighborhood, moving through all location points. | |

Creates a voxel layer source file (netCDF) from categorical 3D points by assigning each voxel the categories of the nearest neighbor in 3D. | |

Uses one of five basis functions to interpolate a surfaces that passes through the input points exactly. |
