Integration and Application of Multi-Source Heterogeneous Data for Waterway Improvement Based on SuperMap
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 2 000 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.
