Thiessen polygon method is a common method of weighing the rain gauge observation according to the area. this method is also called the weighted mean method.
8b Thiessen Polygon Method Pdf Drainage Basin Area The document describes the steps to construct thiessen polygons, which are used to spatially distribute precipitation data from rain gauges across a catchment area. Each thiessen polygon contains only a single point input feature. any location within a thiessen polygon is closer to its associated point than to any other point input feature. this tool is used to divide the area covered by the input point features into thiessen or proximal zones. A. h. thiessen proposed thiessen polygon method to show the area of influence of corresponding weather stations in a given area. however, various fields of sciences and social sciences use this technique of regionalisation for research purposes. The isohyetal method is a contouring technique used to estimate areal precipitation. it involves drawing isohyets, which are lines connecting points of equal rainfall depth, based on measurements from diferent stations.

In this method we assume that each polygon had the rainfall recorded by the central rain gauge, over the entire polygon. since each polygon is a different size, we will need to determine what proportion of the drainage basin each polygon takes up. In order to achieve accurate estimation of the spatial distribution of rainfall, it is necessary to use interpolation methods, for this, the thiessen* method is considered as the most important in engineering praxis. "learn the thiessen polygon method with a step by step solved example and a detailed procedure. this video explains how to calculate average precipitation over an area using this essential. The thiessen polygon method, proposed by dutch climatologist a.h.thiessen, calculates average rainfall by connecting discrete weather stations into triangles and constructing perpendicular bisectors of triangle edges.
