WSDOT - Milepost Values One Tenth Mile

Milepost values at one tenth mile increments on mainline state routes derived from the WSDOT 24K Linear Referencing System for Washington State Routes (LRS). This data is updated annually and represents milepost values on the LRS for the year specified in the LRS_Date field.本数据集提取自华盛顿州交通部（Washington State Department of Transportation, WSDOT）面向华盛顿州州道的WSDOT 24K线性参照系统（Linear Referencing System, LRS），涵盖州级干线公路上每十分之一英里间隔的里程桩数值。该数据按年度更新，其所表征的为LRS_Date字段中指定年份的线性参照系统里程桩数值。
