 This study applies a SAR tomography method called SL1-MMER to retrieve building heights from TERSARX images and uses object-oriented classification to extract building footprints and aggregate derived heights for each building. The Stanford method for persistent scatterers is used to obtain land subsidence rates, which are correlated with building volumes at a local scale but not at a larger scale. Once the volume of buildings exceeds 3.00 by 105 cubic meters, the impact on land subsidence remains stable. This article was authored by Shuai Jia, Jia Yu, Anita Simic-Milis, and others.
