Methods of Interpolation

IDW (Inverse Weighted Distance)

The Inverse Distance Weighted interpolator assumes that each input point has a local influence that diminishes with distance. It weights the points closer to the processing cell greater than those farther away. A specified number of points, or optionally all points within a specified radius, can be used to determine the output value for each location. Use of this method assumes that the variable being mapped decreases in influence with distance from its sampled location. For example. if interpolating a surface of consumer purchasing power for a retail site analysis, the purchasing power of a more distant location should have less influence because people are more likely to shop closer to home.

 

Spline

The Spline interpolator is a general-purpose interpolation method that fits a minimum-curvature surface through the input points. Conceptually, it is like bending a sheet of rubber to pass through the points, while minimizing the total curvature of the surface. It fits a mathematical function to a specified number of nearest input points, while passing through the sample points. This method is best for gently varying surfaces such as elevation, water table heights, or pollution concentrations. It is not appropriate if there are large changes in the surface within a short horizontal distance, because it can overshoot estimated values.

 

Kriging

The Kriging interpolator assumes the distance or direction between sample points reflects spatial correlation that can be used to explain variation in the surface. Kriging fits a mathematical function to a specified number of points, or optionally all points within a specified radius, to determine the output value for each location. The use of kriging involves several steps; exploratory statistical analysis of the data. variogram modeling; then creating the surface and analyzing its optional variance surface. This function is most appropriate when someone know there is a spatially correlated distance or directional bias in the data. It is often used in soil science and geology.

 

 

Trend

The Trend interpolator fits a mathematical function, a polynomial of specified order to all input points. When calculating the mathematical function to describe the resulting surface, Trend uses least-squares regression fit. The resulting surface minimizes the variance in relation to the input point values. That is. at all the known input points, when adding up the difference between the actual values and the estimated values, the variance will be the smallest possible. The resulting surface will rarely go through the known input points.
