由于铁路用地具有线长、点多、面广等多方面特点,其用地管理难度非常大。随着土地不断增值,建设功效便捷的铁路用地管理系统迫在眉睫。文中将基础地理信息数据与铁路相关专题数据有效整合,建设3D数字铁路用地管理系统,全面提升铁路用地的科学管理功能和水平。 Due to the railway line with a long, more points, a wide range of features, the management of land use is very difficult. As the land continues to grow in value, it is imperative to build efficient land management systems for railways. In this paper, the basic geographic information data and railway-related thematic data effectively integrate the construction of 3D digital railway land management system to enhance the scientific management of railway land use functions and levels.
