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

A curated dataset of L-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.

本数据集为东亚地区61个地铁网络的L空间表征（L-space representations）精选数据集，采用JSON格式存储。其网络结构基于非英语开源数据构建，而非标准GTFS（General Transit Feed Specification）数据源，并被统一规整为一致的拓扑格式。主要数据源如下：首尔、釜山、大邱及仁川的地铁数据取自ktdb.go.kr；台北、桃园、台中、高雄的地铁数据取自tdx.transportdata.tw；东京、横滨、京都、神户、札幌、仙台及福冈的地铁数据取自odpt.org；剩余47个地铁系统的数据取自lbs.amap.com（中国本土地图服务提供商）。由于原始数据源多为日语、中文或韩语，若需获取精准的站点名称或遵循当地使用规范，则需具备相应的语言能力。
