SuperMap在航道整治工程中多源异构数据集成应用

Integration and Application of Multi-Source Heterogeneous Data for Waterway Improvement Based on SuperMap

针对内河航道整治工程具有长线型、多区域、隐蔽工程多等特点,传统二维图纸越来越难以准确直观地展示其水上水下空间位置关系以及进行空间分析应用等,结合汉江兴隆至蔡甸段2 000 t级航道整治工程,探索利用SuperMap GIS软件及自研Web端云平台实现航道整治工程航道数字正射影像图(DOM)数据、数字高程模型(DEM)数据、BIM模型数据以及倾斜摄影实景模型等多源异构数据的集成与管理。工程实践表明,利用GIS平台构建航道整治工程空间一体化三维场景能够真实的反映设计师设计意图,同时也能够为工程的规划、建设、运营等方面提供准确的三维信息服务。

Since inland waterway improvement is characterized with long lines,multiple region and hidden works,the traditional 2D drawings are too hard to achieve an accurate and intuitive display of spatial relationship above and under water,or spatial analysis.Based on waterway improvement project for ships up to 2000 tons ranging from Xinglong to Caidian of the Han River,SuperMap GIS software is combined with self-developed web cloud platform to conduct the integration and management of multi-source heterogeneous data such as digital orthophoto map(DOM),digital elevation model(DEM),BIM model,and oblique photography real scene model.Engineering practice shows that GIS-based 3D scene with integrated space can display the designer's intentions,and provide accurate 3D information services for project planning,construction and operation.
