ArcGIS Tutorial # 16 | IDW Interpolation
Geo-statistic is defined as the tools required to analyze the spatial patterns and to compute the estimations of a continuous variable distributed in time at un-sampled areas or space. Inverse Distance Weighted (IDW) is one of such techniques, which unequivocally makes the presumption that thing that is close to one another is have more effect on the anticipated value than those that are progressively far off isolated. To anticipate a value for any unmeasured territory, IDW utilizes the measured values encompassing the forecast area. It gives more prominent weights to points closest toward the forecast zone, and the weights diminish as a function of separation, thus the name Inverse Distance Weighted.
