Localization of vepsians hystorical toponyms in contemporary mapping

The article is analyzed the aspects of the historical mapping of Vepsians toponyms in the Leningrad and Vologda regions of Russia. The purpose of creating the map was to apply all the existing and most of the previously existing Vepsians toponyms to the topographical basis. In addition to the localization of toponyms, the map was prepared by localizing the names of some hydronyms and hills in the Vepsians language. The map was created during several ethnographic expeditions and communication with local residents in 2010- 2019, as well as the analysis of previously collected toponymic material. The implementation of the project to create a map is outlined in the text. The main problems of localization of Vepsians toponyms are described and approaches to their solution are proposed. The main sources of information for the toponyms mapping are listed. The author assesses the prospects of distribution and use of toponymic maps in scientific research.
