The iDAI.gazetteer is a webservice, which connects toponyms with coordinates and is meant to work in two directions. Internally it serves as the authority file for all geo-related information and information-systems of the German Archaeological Institute. It is also supposed to connect this data with other worldwide gazetteer-systems.
Youtube ScreencastPlease note: The iDAI.gazetteer is a collaborative resource and thus just as good as their users are. If you notice missing places, duplicates, flawed datasets or places without coordinates, please send a message to idai.gazetteer@dainst.de. Please always state the identification number (gazetteer-ID). In case of suggestions for new places beside the names the coordinates are helpful. Many thanks!
