提出了一种考虑公路线形特征的线性参照系,旨在解决公路数据库中空间数据冗余、公路事件在小比尺电子地图上容易偏离公路等问题.通过识别公路线形、压缩冗余数据和分配线性坐标来建立线性参照基准,建立相应的线性参照算法,动态建立公路事件与二维大地坐标间的联系.在公路管理中的实际应用表明,此种参照系具有简便易行和精度高的特点,能够较好地满足实际工程要求.

A linear reference system considering the linear characteristics of highways is proposed, which aims to solve the problems of spatial data redundancy in highway database and easy deviation of highway events on small scale electronic maps. By identifying highway alignment, compressing redundant data and assigning linear coordinates, a linear reference reference is established, and the corresponding linear reference algorithm is established to dynamically establish the relationship between highway events and two-dimensional geodetic coordinates. The practical application in highway management shows that this reference system has the characteristics of simplicity and high precision, and can better meet the actual engineering requirements.
