A curated data set of P-space representations for 61 East Asian metro networks

A curated dataset of P-space representations in .json format for 61 metro networks in East Asia. Network structures are built from non-English open data rather than standard GTFS feeds and harmonized into a consistent topological format. Primary sources are ktdb.go.kr for Seoul, Busan, Daegu, and Incheon; tdx.transportdata.tw for Taipei, Taoyuan, Taichung, and Kaohsiung; odpt.org for Tokyo, Yokohama, Kyoto, Kobe, Sapporo, Sendai, and Fukuoka; and lbs.amap.com (a Chinese local map provider) for the remaining 47 systems. Since the raw data sources are often in Japanese, Chinese, or Korean, language skills may be required if exact station names or local conventions are of interest.
