摘要:
随着大数据时代的到来，铁路选线从传统的地形选线、地质选线、环保选线等方式转变为利用地形、地质、环保、拆迁等多源数据信息高度融合的三维地形选线以及快速构建模型的时代。为了满足基于多源地理和地质数据的铁路选线与模型快速构建的需求，提出了一种对海量数据管理以及海量瓦片化的三维模型进行简化抽稀的方法，实现了快速数据的加载和渲染调度，并快速进行网络分发。该研究成果可为铁路选线设计与模型快速构建提供技术支撑。
Abstract:
With the advent of the big data era，railway route selection has evolved from traditional methods such as topographic selection，geological selection，and environmental selection to a three-dimensional route selection that integrates multi-source data，including topography，geology，environment，and land acquisition. Furthermore，it is now possible to rapidly construct models. In order to meet the requirements of railway route selection and rapid modeling based on multi-source geographic and geological data，this paper proposes a method that involves managing massive data，simplifying and rarefying tile-based three-dimensional models，and achieving fast data loading，rendering scheduling，and network distribution. The results provide technical support for railway alignment design and rapid model construction.
