摘要
由于地质条件的影响及城市化进展的不断加快,南京河西地区地面沉降日趋明显。本文以2007—2011年16景日本ALOS PALSAR卫星升轨数据为例,采用SBAS技术分析了河西地区的沉降趋势,反演了研究区的地表形变场,并与水准测量数据进行了对比,验证了SBAS用于沉降监测的准确性和时效性。
Due to the influence of geological conditions and the accelerating of urbanization progress, land subsidence of Hexi area, Nanjing has become increasingly obvious. In this paper 16 views Japan ALOS PALSAR satellite ascending orbital data from 2007 to 2011 are taken as an example. By using SBAS technology to analyze subsidence trend of Hexi area, the surface deformation field of study area was inversed. Compared with measurement data, the accuracy and timeliness of the SBAS for subsidenee monitoring are verified.
