南京高分InSAR地表沉降数据

南京高分InSAR地表沉降数据可以应用于到地面沉降地质灾害监测、轨道交通和基坑等施工区沉降监测、既有道路及建筑物沉降监测等应用场景，用户可以指定南京某一区域范围，获取2019年6月21日至2022年5月11日，每隔约1～2个月一期，共计20期（见表1），3m分辨率的地面沉降情况，目前该产品有3928802条数据，Shapefile格式，存储大小约为1.4GNanjing Gaofen InSAR surface subsidence dataset can be applied to scenarios including geological disaster monitoring of ground subsidence, subsidence monitoring in construction zones such as rail transit projects and foundation pits, as well as subsidence monitoring of existing roads and buildings. Users can specify a designated regional area within Nanjing to acquire ground subsidence data with 3-meter resolution spanning from June 21, 2019 to May 11, 2022. The dataset contains 20 sessions, with each session collected at an interval of approximately 1 to 2 months (see Table 1). Currently, this dataset holds 3,928,802 data records, is stored in Shapefile format, and has a total storage size of around 1.4 GB.
