What is the interpolation method used in spline?
Available with Spatial Analyst license. Available with 3D Analyst license. The Spline tool uses an interpolation method that estimates values using a mathematical function that minimizes overall surface curvature, resulting in a smooth surface that passes exactly through the input points.
How does the spline tool in ArcGIS Pro work?
Available with 3D Analyst license. The Spline tool uses an interpolation method that estimates values using a mathematical function that minimizes overall surface curvature, resulting in a smooth surface that passes exactly through the input points. Conceptually, the sample points extrude to the height of their magnitude.
What’s the difference between tension and regularized spline?
There are two Spline types: Regularized and Tension. The Regularized type creates a smooth, gradually changing surface with values that may lie outside the sample data range. The Tension type controls the stiffness of the surface according to the character of the modeled phenomenon.

How does a spline interpolate a raster surface?
Interpolates a raster surface from points using a two-dimensional minimum curvature spline technique. The resulting smooth surface passes exactly through the input points. The greater the value of Number of Points, the smoother the surface of the output raster.
How does the weight parameter in spline work?
For the Regularized Spline method, the Weight parameter defines the weight of the third derivatives of the surface in the curvature minimization expression. The higher the weight, the smoother the output surface. The values entered for this parameter must be equal to or greater than zero.
