Street Centerlines Open Data

This data represents the centerlines of streets in the City of Boulder. Lines follow the center of each street and alley and are broken at intersections. Divided streets and highways are represented with a centerline for each direction to represent the dual carriageway. Street suffix abbreviations are modeled from the USPS standards. This data can be used to perform network analysis or for address geocoding. This data participates in a network (TRANS.STREETSNETWORK) with the TRANS.STREETS_ND_Junctions point feature class.本数据集涵盖博尔德市（City of Boulder）内所有街道与小巷的中心线。所有中心线均沿对应道路的中线绘制，并在交叉口处断开。对于分隔式街道及公路，本数据集会为每个行车方向各生成一条中心线，以此表征双向分隔车道（dual carriageway）的道路结构。街道后缀缩写均遵循美国邮政管理局（USPS）的标准进行建模。本数据集可用于开展网络分析（network analysis）或地址地理编码（address geocoding）。本数据集与TRANS.STREETS_ND_Junctions点要素类（point feature class）共同参与构建TRANS.STREETSNETWORK网络。
