三维GIS引擎与骨干河网防洪模型的融合与分析

Integration and Analysis of 3D GIS Engine and Flood Control Model Of Backbone River Network

GIS(地理信息系统)经过多年的发展,在资源管理、环境监测、城市规划、土地管理、交通、水利、林业等行业广泛应用,GIS在应用中取得较快发展,三维GIS孕育而生,它以更逼真(全要素、三维)、更精细、更精确、更广泛(室内、地下、水下)、更快速、更实时和更便于进行统计分析被人们所追捧。文章以水利的防洪模型为应用场景,探索了三维GIS引擎与骨干河网防洪模型的融合与分析,阐述了城区骨干河网的三维建模、GIS系统的三维融合、城市防洪模型建立、防洪模型系统的推演分析等内容,以供大家参考。

After years of development,GIS(Geographic Information System)has been widely used in resource management,environmental monitoring,urban planning,land management,transportation,water conservancy,forestry and other industries.GIS has made rapid development in application,and 3D GIS is born with more lifelike(full element,3D),more precise,more accurate,more extensive(indoor,underground,underwater),faster and more real time and more convenient statistical analysis is popular.Taking the Flood Control Model of water conservancy as the application scenario,this paper explores the integration and analysis of the three-dimensional GIS Engine and the flood control model of the backbone river network,expounds the three-dimensional modeling of the urban backbone river network,the three-dimensional integration of the GIS system,the establishment of the urban flood control model,the deduction and analysis of the flood control model system,etc.
