More Information
Summary:The invention provides a GIS-based reconstruction and extension road model optimization method. The method comprises the steps of preprocessing original GIS data; the original GIS data comprises design route data and elevation data; classifying and sorting the geographic information; performing data format conversion and type conversion processing; carrying out coordinate system definition and coordinate data conversion; establishing a road model; the road model comprises a newly built road model and an existing road model; and carrying out connection processing on the new model and the old model. According to the method, the existing road longitudinal section line shape is fitted by adopting the least two algorithm on the basis of the laser point cloud technology, and after optimization processing, a connection optimization scheme of the new and existing road models can be completed. 本申请提供一种基于GIS的改扩建公路模型优化方法，方法包括：对原始GIS数据进行预处理；原始GIS数据包括设计路线数据和高程数据；对地理信息进行分类整理；进行数据格式转换以及类型转换处理；进行坐标系定义以及坐标数据转换；建立公路模型；公路模型包括新建公
