To respond to UN resolutions and UN data needs, this Working Group on Toponymic Data Files and Gazetteers addresses various issues of toponymic data processing, including the creation, maintenance and outputs of toponymic data files (including gazetteer production) and aspects of toponymic data exchange formats and standards.

Issues of providing geographical names information within national and international spatial data infrastructures (SDIs) through web (gazetteer) services and multipurpose toponymic database solutions in the context of SDIs as well as the utilization of volunteered geographic information and crowd sourced data are becoming more and more important. Furthermore, the issue of appropriate definitions for gazetteers and data types and of general feature types/categories relates with the agenda of the WG TDFG.

This homepage was created for the Working Group on Toponymic Data Files and Gazetteers (WG TDFG) of the United Nations Group of Experts on Geographical Names (UNGEGN).
