Multilingualization Experiment of Geographical Name Information Using Vector Title Format

Abstract. Multilingualization of geographical name information has been required to support foreign visitors to the Olympic Games and the Paralympic Games to be held in Tokyo in 2020 and to correspond to the rapid increase of foreign visitors in recent years. GSI has prepared geographical name information in English and it has been already released. To expand this effort, we have conducted the experiment to translate geographical name information in Japanese and English into French, Korean, Simplified Chinese, and Traditional Chinese automatically and to prepare a multilingual map using vector tile format. To be specific, we prepared transformation rules for translation of geographical name information, and implemented the Javascript codes of transformation rules to deploy in combination with the existing Javascript library group which controls display on the web map. Thus, we developed a web map system which automatically generates geographical name information in these targeted languages on web browsers.
