| 摘 要： | 以松花江流域为例,将VRGIS技术应用在数字流域的飞行模拟、洪水淹没分析中,以三维模拟仿真的手段,真实再现松花江及其沿岸的生态景观。结果显示,沿松花江哈尔滨段的上游到下游,动态地俯视模拟其沿线的地形、地貌、洪水淹没状况,浏览者可以获得比二维数字地图更为直观的图像。

| Abstract: | Tt applies the visual GIS technology to the flying simulation,inundation simulation and analysis of digital river basin. It is a case of Songhuajiang river valley.By using 3D simulation Songhuajiang River is virtnalizd, along with its entironment around. By using flying views between upriver to downriver of Songhuajiang River, the landscape and detail information of the terrain, physiognomy and vegetation cover are much more visual and vivid than by viewing the digital mosaiced image. |
