基于Sentinel-1A数据的矿区地面沉降监测应用研究

Application of Sentinel-1A Data in Monitoring Land Subsidence in Mining Area

哨兵一号(Sentinel-1A)数据是目前可供大量免费下载的SAR数据,文章简单介绍了Sentinel-1A的数据特点,以济宁矿区为研究区,开展基于Sentinel-1A数据的双轨D-InSAR监测矿区地面沉降的探索,根据干涉数据的读取到形变图生成的数据处理流程,生成了一系列清晰的结果图。研究表明:利用Sentinel-1A数据可以对矿区地面沉降进行有效的监测,进而为煤矿区的合理开采和可持续发展提供一定的理论依据。

The Sentinel-1 A data is freely available SAR data that can be largely downloaded. From this, the Sentinel-1 A data is briefly introduced in this paper. With the Jining mining area as the study area, and the two-pass D-InSAR technique based on Sentinel-1 A data is explored, then the whole process of data reading from interferometric images to subsidence map is completed, and a series of clear results are generated. The results show that the Sentinel-IA can be used to monitor the land subsidence in mine area, thus a theoretical basis for the rational exploitation and sustainable development in mining area is provided.
