How to create Thiessen polygon in ArcGIS?

In this tutorial, I have explained uses of Thiessen polygon and how to prepare it ArcGIS. The Thiessen polygon is a commonly used methodology for computing the mean areal precipitation for a catchment from rain gauge observations which was presented by A.H. Thiessen (1911). The Thiessen method is based on the assumption that measured amounts at any station can be applied halfway to the next station in any direction, which means that for any point rainfall is equal to the observed rainfall at the closest gauge. The weights of the rain gauges are computed by their relative areas, which are estimated with the Thiessen polygon network. The polygons are formed by the perpendicular bisectors of the lines joining nearby stations. The area of each polygon is used to weight the rainfall amount of the station in the center of the polygon. If the amount for any station is missing, the polygon must be changed. The Thiessen method is unable to consider orographic differences in rainfall distributions. ************************************************************************************************** Workshop Alert on An Integrated MCDM approach for Drought Vulnerability Assessment in ArcGIS https://www.aigr.co.in/ ************************************************************************************************** Enrollment link https://www.aigr.co.in/page/an-integr... ******************************************************************************************************* UDEMY Course Rainfall Indices for MCDM models in ArcGIS: how and Why?
