摘要
To describe the dynamic process of flood routing intuitively and realistically when storm surge disaster occurs,a method for ArcGIS data and Google Earth(GE) data integration is proposed,which realizes the importing and integrating of basic geographic information into GE. Based on SketchUp and AutoCAD software,threedimension(3D) visualization of seawall and other tidal defense structures is achieved. By employing Microsoft Foundation Class Library(MFC),the related system modules and storm surge flood routing dynamic visualization system are developed. Therefore,dynamic visualization of flood routing process and interactive query of submerged area and inundated depth are implemented. A practical application case study of Tianjin Binhai New Area provides decision-making support for coastal seawall planning and storm surge disaster prevention and reduction.
To describe the dynamic process of flood routing intuitively and realistically when storm surge disaster occurs, a method for ArcGIS data and Google Earth （GE） data integration is proposed, which realizes the impor- ting and integrating of basic geographic information into GE. Based on SketchUp and AutoCAD software, three- dimension （3D） visualization of seawall and other tidal defense structures is achieved. By employing Microsoft Foundation Class Library （MFC）, the related system modules and storm surge flood routing dynamic visualization system are developed. Therefore, dynamic visualization of flood routing process and interactive query of sub- merged area and inundated depth are implemented. A practical application case study of Tianjin Binhai New Area provides decision-making support for coastal seawall planning and storm surge disaster prevention and reduction.
