Setting the Record Straight: On the Russian Origins of Dasymetric Mapping

Abstract

A growing volume of dasymetric mapping research poses a very important and still unanswered question about the historical origins of this method. Conflicting versions offered in the literature propagate confusion among researchers. This article attempts to clarify who invented the dasymetric mapping method and first published dasymetric maps, as well as when this took place. Evidence presented in this article suggests that the Russian geographer Benjamin Semenov-Tian-Shansky must be considered the originator and first practitioner of modern dasymetric mapping. He developed this technique in 1911 and published a substantial number of maps in the 1920s. Reviews and descriptions of Semenov-Tian-Shansky's works in English appeared in the Geographical Review a decade before the frequently cited article by John Wright was published in the same journal.
