Minimum Curvature

The minimum curvature gridding method is a smoothing interpolator that produces a grid by repeatedly applying an equation to the grid. It continues to apply the equation until changes in the grid node values are less than the maximum residual value, or until the maximum number of iterations is reached.

Change the default parameters by clicking <More Options> in the Kernel Gridding window. This will allow you to change:

Minimum Curvature Parameters – Change the maximum iterations and maximum residual.
Input Data Restriction – Restrict the input data to positive or negative values, and minimum and/or maximum values.
Duplicated Data Treatment - Specify how to grid an area where two or more input data points fall at the same location.
Options for Gridding Initialization – Control how minimum curvature weights the input data.
Data Outside Gridding Area – Select to include data values outside your area of interest in the gridding calculation.
Data Output Option – Limit the range of output grid node values.
