The time series interferometric synthetic aperture radar (InSAR) technology can provide us with large-area, high-resolution, and high-precision ground deformation monitoring. In this study, the time series InSAR technology and the strategy with long- and short-time baseline networking are used to obtain the surface deformation along the line of sight of Nanchang City based on the six-year (from December 2015 to December 2021) Sentinel-1 data. Longer datasets and better baseline strategies allow us to obtain more stable deformation results of Nanchang City than other researchers. The results of surface deformation show that the overall surface of Nanchang City is stable, but there are several obvious subsidence funnels. We carried out a field survey on four areas with significant surface subsidence. We considered that these subsidence areas may be related to soil compaction, building construction, and groundwater extraction. Based on the surface deformation results around the subway line, we analyzed the impact of subway construction on the surface along the line and identified the sections that need to be focused on by the managers to prevent the deformation area from affecting the surrounding buildings and subway line operation safety.<\/jats:p>","DOI":"10.3390\/rs15133253","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T03:14:56Z","timestamp":1687749296000},"page":"3253","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Surface Subsidence of Nanchang, China 2015\u20132021 Retrieved via Multi-Temporal InSAR Based on Long- and Short-Time Baseline Net"],"prefix":"10.3390","volume":"15","author":[{"given":"Hua","family":"Gao","sequence":"first","affiliation":[{"name":"Key Laboratory of Natural Disaster Monitoring, Early Warning and Assessment of Jiangxi Province, School of Geography and Environment, Jiangxi Normal University, Nanchang 330022, China"},{"name":"Key Laboratory of Poyang Lake Wetland and Watershed Research Ministry of Education, Nanchang 330022, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luyun","family":"Xiong","sequence":"additional","affiliation":[{"name":"Guangzhou Urban Planning & Design Survey Research Institute, Guangzhou 510060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiehong","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Natural Disaster Monitoring, Early Warning and Assessment of Jiangxi Province, School of Geography and Environment, Jiangxi Normal University, Nanchang 330022, China"},{"name":"Key Laboratory of Poyang Lake Wetland and Watershed Research Ministry of Education, Nanchang 330022, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Lin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Natural Disaster Monitoring, Early Warning and Assessment of Jiangxi Province, School of Geography and Environment, Jiangxi Normal University, Nanchang 330022, China"},{"name":"Key Laboratory of Poyang Lake Wetland and Watershed Research Ministry of Education, Nanchang 330022, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangcai","family":"Feng","sequence":"additional","affiliation":[{"name":"Key Laboratory of Metallogenic Prediction of Nonferrous Metals and Geological Environment Monitoring, Central South University, Ministry of Education, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,24]]},"reference":[{"key":"ref_1","unstructured":"Liao, M.S., and Wang, T.
