摘要
自本世纪初起,由于采用了"数字滑坡技术"和高分辨率遥感数据,滑坡遥感成为能更准确地定性、定位、定量的滑坡调查手段,可进行区域的和大型个体滑坡的详细调查和监测研究。"数字滑坡"技术的实现基于滑坡地学原理并依赖遥感技术、数字摄影测量及图像处理技术、G IS技术和计算机技术的支持。该项技术大致可分为4大部分:滑坡识别、滑坡基本信息获取、信息存贮和管理及空间分析。20世纪末期以来,数字滑坡技术在应用中不断完善和获得新进展。
With the adoption of the Digital Landslide Technique and high resolution remote sensing data, remote sensing has enabled more accurate qualitative and quantitative survey of regional landslides and monitoring of large landslide since the beginning of 21th Century. Digital Landslide Technique is based on geoscience principles of landslide and depends on the support of remote sensing, digital photogrammetry and image - processing, GIS and computer techniques. It can be divided into four parts, namely, landslide identification, capturing of basic landslide information, information storage and management, and spatial analysis. The technique has perfected and developed itself continually during the practice since the end of the~ 20th Century.
