摘要
研究目的:基于GIS的铁路选线设计,关键的技术实现是空间数据的统一与转换,建立在地理元数据标准之上的统一空间数据架构,是实现从工程数据到地球空间数据转换的依据,通过空间变换机制,实现工程数据与GIS空间数据的统一,并运用GIS的空间数据组织能力、空间分析与三维建模表达技术,为工程设计提供作业数据与直观的分析应用平台。研究结论:基于GIS的铁路选线设计,不仅为基于空间分析的方案策划、工程设计、数据获取、数量统计与三维展示提供了广泛地面向空间信息技术的应用平台,也为大区域的空间工程建设提供了更为合理的数据组织基础,展现出与传统平面设计的优势,为大区域工程设计提供了一种更科学的设计手段。
Research purposes:The key technology of GIS-based railway alignment design is the integration and transformation of spatial data,and the unified spatial data framework based on the geodata standard is the basis for transforming the engineering data into the geospatial data.By using a comprehensive space transformation mechanism,the unification of engineering data with GIS spatial data is realized and the visual analysis and applicable platform can be offered for the engineering design by using the GIS organizational capacity,spatial analysis and 3D modeling expression technology.Research conclusions:GIS-based railway lalignment design not only provides an extensively applicable platform for engineering planning,engineering design,data acquisition,quantitative statistics and 3D display based on space information technology,but also provides a more reasonable basis and a new and more scientific design means for data organization for space construction of large area.This reflects the advantages of GIS-based digital railway alignment design compared with the traditional plane graphic design.
