What is IDW Interpolation Explained in GIS about?

Inverse Distance Weighting (IDW) interpolation is a method used to estimate unknown values based on known data points, emphasizing that closer points have a greater influence than those further away. The process involves setting parameters such as search distance, number of closest points, and power settings to adjust the interpolation results. IDW is flexible and can incorporate barriers to refine estimations, making it useful in various applications like estimating rainfall or elevation in GIS analysis.
