Instructions for use

The Barrier Splines interpolation method uses barriers to interpolate points to generate a grid surface. Obstacles only support line objects for the time being. It is often used to generate iso-surface grids from elevation points and fault data.

• There must be a numeric field in the Point Dataset used for interpolation as the interpolation field.
• The Barrier Splines interpolation method is similar to the Splines interpolation method, except that the Barrier Splines interpolation method takes into account the discontinuity between the barrier at the input and the Point Dataset to be interpolated.

Function entrance

• Spatial Analysis tab-> Raster Analysis group-> Interpolation Analysis-> Barrier Splines.
• Toolbox, Raster Analysis, Interpolation Analysis, Barrier Splines.

Parameter Description

• Set public parameters for Interpolation Analysis, including Source Data, Bounds, Result Data, and Environment Settings. For the settings of public parameters such as source data, Bounds, and Result Data, please refer to Public Parameter Description .
• Obstacle Dataset: Data for constrained interpolation. Only Line Dataset is supported.
• Expected points: the number of points expected to participate in the interpolation operation.
• Smoothness: Enter the value of Smoothness. The value range is 0,1. The default value is 0.1. Smoothness refers to the degree of approximation between the interpolation function curve and the point. The greater the value, the greater the deviation between the function curve and the point, and vice versa.
• Tension:: Enter the Tension: value. The default is 40. Tension: It is used to adjust the characteristics of the Raster Data surface of the result. The greater the tension, the smaller the influence of each point on the Calculate Result during interpolation, and vice versa.
