武都地区位于甘肃东南边陲,是甘肃惟一的长江流域。武都地区是国内受泥石流危害最为严重的地区之一。本研究通过对遥感影像的目视解译和人机交互解译来识别泥石流灾害体。同时结合GIS技术,进行研究区域三维场景的构建,实现三维景观的漫游、飞行。通过GIS中空间数据的强大管理功能,实现对数据库的设计和对空间数据的管理。 Located in the southeastern border of Gansu, the Wudu area is the only Yangtze River valley in Gansu. Wudu area is one of the areas hardest hit by debris flow in China. In this study, debris flow hazards were identified through visual interpretation and human-computer interaction interpretation of remote sensing images. At the same time, combined with GIS technology, the study of the construction of three-dimensional scene area, to achieve three-dimensional landscape roaming, flying. Through the powerful spatial data management capabilities in GIS, the design of the database and the management of spatial data are realized.
