CTDOT LRS Mileage Guide

This data displays the LRS mileages to a .01 accuracy. It represents a real world driven measure from the lateral extension of the curb at the beginning and end of a particular roadway. This three dimensional measure is then set in the two dimensional Linear Referencing Services (LRS) space and the lengths are distributed along particular segments which in some cases may cause a stretching or shrinking effect to the real world measures. Also not all reverse measurements, particularly in an overlap section, are able to be represented due to the nature and digitizing rules when creating the LRS.本数据集以0.01的精度展示了线性参照服务（Linear Referencing Services，LRS）里程数据。该数据源自特定道路起止位置处路缘侧向延伸范围的实地测量值。随后将该三维测量值映射至二维线性参照服务（LRS）空间中，并沿特定路段分配长度，此过程在部分场景下会对实际测量值产生拉伸或收缩效应。此外，受LRS构建时的固有特性与数字化规则限制，并非所有反向测量值（尤其是重叠区段内的测量值）均可被完整呈现。
