In this paper, 7 ENVISAT ASAR images acquired from November 2004 to March 2006 are processed successfully to extract the interferograms and the subsidence map in KaiLuan mining area using the two-pass D-InSAR method. 14 major mining subsidences are ascertained in test area at the study period. 3 typical subsidence areas are taken as examples, by analyzing interferograms, subsidence profiles and the...
It could be concluded that all multi-objective evolutionary algorithms draw their strength from two aspects: convergence and diversity. In order to achieve these goals, This paper proposes a hybrid methods that combines GA with simplex search method for multi-objective optimization using preference order ranking. Preference order ranking is used as fitness assignment methodology to accelerate the...
Monitoring and governing the regional land subsidence along the highway and other linear projects has become an important basic work for the normal construction and operation in these regions. In this paper, by using the method of multi-track PS-InSAR integration, the land subsidence velocity varying with time along the JingHu highway (Beijing-Hebei) was studied with adjacent orbits ENVISAT ASAR data...
The problem of community structure detection in complex networks has been intensively investigated in recent years. Many algorithms were proposed based on optimization modularity. To overcome the solution limitation drawbacks of modularity function, as a new measure, modularity density for measuring the community structure was introduced. In this paper, we propose a genetic algorithm for detecting...
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,...
