1923 R. E. Horton in Monthly Weather Rev. (U.S.) 51 349/1 The true average rainfall was assumed to equal the arithmetic mean of all the records. This was checked by the application of the Thiessen method.
1949 Wisler & Brater Hydrology iv. 86 Thiessen mean, in the application of this method, adjacent stations are joined by straight lines... Perpendicular bisectors are erected on each of these lines thereby forming a series of polygons, each containing one and only one rainfall station.

1983 Sci. Amer. Nov. 132/2 If one draws lines midway between the monuments to divide the landscape into separate units (a process geographers call forming Thiessen polygons), one finds that with few exceptions the landscape is divided into roughly equal productive units.
1984 Rocky Mountain Jrnl. Math. 14 i. 123 Thiessen regions are also referred to in the literature as tiles and polygons, and have been associated with the names Dirichlet and Voronoi.
