| Abstract | In this work, DInSAR technique has been applied to the monitoring of mining induced land subsidence in many areas. In this paper, the DInSAR technique is used to process the space borne SAR data including C band ENVISAT ASAR and L band JERS, PALSAR SAR data to derive the temporal land subsidence information in Fengfeng coal mine area, Hebei province in China. Since JERS do not have precise orbit, an orbit adjustment must be accomplish before the DInSAR interferogram was formed. We designed a images coregistration method based on the imaging geometry of interferometric SAR, and an external DEM. We analyzed 8 differential interferograms derived from JERS SAR, PALSAR, ENVISAT ASAR data. In our analysis, the DInSAR results were compared with leveling data that show high consistency. The characteristics of phase pattern on these C band and L band deformation interferograms were compared; we can notice that in most situations, the obtained deformation pattern on the surface is not the same of L and C band. And at last the feasibility and limitations in mining subsidence monitoring with DInSAR were analyzed. The experimental result shows that both C band and L band can accomplish monitoring mining area subsidence, but C band has more restrict conditions of its perpendicular baseline. In order to get a satisfactory outcome in mining area subsidence by DInSAR method, the time series of SAR images of every visit period and SAR deformation interferograms should be archived. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
