Which interpolation method is best?

Radial Basis Function interpolation is a diverse group of data interpolation methods. In terms of the ability to fit your data and produce a smooth surface, the Multiquadric method is considered by many to be the best.

What is the best interpolation method for elevation?

Today, perhaps the most widely used technique for interpolating elevation from contours is Hutchinson's ANUDEM algorithm, which can be used in the ArcGIS system via the TOPO TO RASTER command. This interpolation method not only uses contours, but also uses surface drainage lines such as streams and rivers.

Which interpolation method is best in image processing?

BICUBIC INTERPOLATION

Bicubic produces noticeably sharper images than the previous two methods, and is perhaps the ideal combination of processing time and output quality.

What are the two main types of interpolation approach?

They are: Linear Interpolation Method – This method applies a distinct linear polynomial between each pair of data points for curves, or within the sets of three points for surfaces. Nearest Neighbour Method – This method inserts the value of an interpolated point to the value of the most adjacent data point.
