#  Temporal Gazetteer (TGAZ) 

 



The [Temporal Gazetteer (TGAZ)](https://chgis.hudci.org/tgw/) is a search engine and machine-readable API for historical placenames. Built upon toponymic databases of historical placenames from the [China Historical GIS](http://www.fas.harvard.edu/~chgis/), the [Toponimika - Historical Gazetteer of Russia](http://fungdavis.github.io/fungHGR/), and the [Gazetteer of Historical Monasteries in Greater Tibet](https://worldmap.harvard.edu/maps/tibet/Xbh), the TGAZ system architecture provides a method for integrating historical place names with other Linked Open Data systems, such as Pelagios / Recogito and MARKUS. TGAZ was designed and developed by [Lex Berman](https://dbr.nu/bio/) with programming by [Bill Hays](https://www.linkedin.com/in/william-hays-1a50616/) and was originally hosted on maps.cga.harvard.edu/tgaz/

This interface accepts queries for placenames in UTF-8 encoded strings or glyphs (for example, Chinese characters, Russian Cyrillic script, and Tibetan Script, as well as Romanized transcriptions). Each placename recorded in the database is referred to as a *spelling*. A brief look at the project in diagrams ([PDF](https://tgaz.fudan.edu.cn/tgaz/docs/TemporalGazetteer_Slides_20140501.pdf)).
