遥感与地理信息集成系统在城市活断层研究中的初步应用
|
摘要
遥感技术应用于地震研究中的一个重要方面是利用遥感图像的宏观性解译地震活动的构造背景。该项目主要利用遥感及GIS地理信息软件合成数字遥感图像并利用数字高程模型DEM生成三维地貌影像图,与城市房屋等数字图层叠加,建立与地理图层相连的属性数据库,实现断层与地面建筑关系的实时查询,并对用于构造背景的三维立体模型的显示、可视化飞行技术进行初步研究,以期在城市活断层研究中得到应用。
An important aspect of remote sensing study of earthquakes is at explaining structure background of seismic activity using remote sensing image macroscopically. The digital remote sensing image can be composed through remote sensing and geographical information system software; meanwhile, the digital height model DEM can be formed, the 3D geographical map be shaped, and the attribute database connecting to geographical maps be built. The 3D-model display and visual flying technology were made a preliminary study for detecting seismic faults in the city of Urumqi that would be used in structure background. The result can be applied to the detection of the active faults in Urumqi.
