PTV Metro Tram Routes

This layer depicts a spatial object (polyline) representing metropolitan tram routes. Each polylines represents a unique route variation. Each route has attributes that describe route, trip headsign (direction), route length, first/last stop, number of stops and operator name. The data has been generated from the PTV GTFS data with extra attributes from PTV's TransNet database. \nThis dataset supersedes "PTV_TRAM_ROUTE".\nThis dataset was first loaded into the VSDL in March 2018 and will be updated approximately quarterly.本图层展示了代表大都市有轨电车线路的空间对象（折线 (polyline)）。每条折线均对应一条独特的线路变体。每条线路均包含用于描述线路、行程目的地标识（方向）、线路长度、首末站点、站点数量以及运营方名称的属性字段。本数据集源自PTV的GTFS数据，并补充了PTV TransNet数据库的额外属性字段。 本数据集替代了"PTV_TRAM_ROUTE"数据集。 本数据集于2018年3月首次导入VSDL，后续将按季度进行更新。
