Application of SBAS Technique in Surface Subsidence Monitoring of Nanjing Hexi Area

doi:10.13474/j.cnki.11-2246.2017.0077

Abstract

Abstract: 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 subsidence monitoring are verified.

Key words: SBAS, subsidence monitoring, interference, deformation field
