#  Temporal Gazetteer 

 



 **[TGAZ Search Engine and API](http://maps.cga.harvard.edu/tgaz/)**

 The Temporal Gazetteer (TGAZ) 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.

 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](http://maps.cga.harvard.edu/tgaz/docs/TemporalGazetteer_Slides_20140501.pdf)).

 Funding was provided by the [NSF IUCRC Spatio-Temporal Thinking Innovation Center](/spatiotemporal-innovation-center).
