Through integrated usage of multiple - source information , data fusion can get more objective and intrinsic knowledge of certain target 通过多源信息融合,可以克服单一传感器影像中数据的模糊性,提高信息利用率,增强数据的可靠性和多用性。
Based on the merging technique of multiple - source and multiple - time rs images , the regional investigation of landslide could save a large number of labor forces and material resources , at the same time , it satisfied the vast - area synthetical investigation and high - resolution local investigation to single hazard 摘要采用多源多时相遥感数据融合技术进行区域滑坡灾害调查,可节约大量人力物力,同时满足了大面积综合调查和灾害体高分辨率局部调查的要求。
Standing in the point of monitoring of landslide , the paper told some typical techniques of multiple - source and multiple - time rs images and the application in the monitoring of landslide , desired that it could take active effects to forming factor of landslide 、 forcasting before hazard 、 evaluating after hazard and prevention of hazard in the investigation of landslide 本文从滑坡灾害监测的角度,阐述了遥感多源多时相融合技术中的一些典型方法及其在滑坡调查中的应用,以期在区域滑坡灾害调查中起到积极作用。
