| 摘 要： | 河道数字地形建模是根据河道测点数据创建河道地形模型DEM,包括河道不规则三角网数据模型(TIN)、河道规则格网数据模型和河道等高线数据模型。以长江南京段的实际测点数据为例①,以ArcGIS Engine为开发工具,参考反映河道地形特征的控制测点构建河道TIN,以突出河道弯曲性、深槽连续性、边坡平滑性等地形特征;由TIN创建规则格网模型和等高线模型。同时,在三维显示时利用"加边"处理来填补岸边数据满足可视化效果。

| Abstract: | The digital terrain model of a river channel is built according to the elevation survey points of the river.It consists of building the TIN model,GRID model and contour model of the river channel.Here taking the data from the survey points in Nanjing reach of Yangtze River for example and taking ArcGIS Engine as a tool,the TIN is built according to the characteristic points of the river channel.Then,the GRID model and contour model are originated from the TIN model,but when using the three-dimensional displ... |
