“…The interferogram is generated by complex conjugate multiplication of the interferometric image pair. D-InSAR technique is a method that the phase information of radar carrier is used to obtain the ground deformation (Fan, H., 2011;Chen, B., 2013). In the repeat mode, if the ground deformation is happened during the two images being captured, the interferometric fringes generated by these two images mainly include some phase information as follows:  is the main factor to be removed.…”

ABSTRACT:Differential Synthetic Aperture Radar Interferometry (D-InSAR) as a new earth observation technique has become an important tool for monitoring ground movements caused by underground coal mining. However, the low resolution and accuracy of Digital Elevation Model (DEM) cause more error value of InSAR line-of-sight(LOS) surface deformation measurement. In this paper, a couple of Radarsat-2 and a pair of TerraSAR with SRTM, GDEM and LiDAR DEM are processed respectively to reveal the subsidence basin and the results have been compared each other. It illustrate that the accuracy of D-InSAR results been better improved by the high accuracy and resolution DEM. Corresponding author

“…The most important advantage of this technology is the direct acquisition of dense 3D point cloud data, which can reflect details on the surface of detected objects [5,6]. In recent years, several researchers have successfully taken advantage of 3D laser scanning technology in monitoring and studying structures, landslides, and surface subsidence [7][8][9]. Girardeau-Montaut et al proposed contrasting 3D point clouds in different temporal points to detect changes in stone carvings and proposed a false change problem in the detection process [10].…”

Abstract:The timely detection of gold foil damage in gold-overlaid stone carvings and the associated maintenance of these relics pose several challenges to both the research and heritage protection communities internationally. This paper presents a new method for detecting gold foil damage by making use of multi-temporal 3D LiDAR point clouds. By analyzing the errors involved in the detection process, a formula is developed for calculation of the damage detection threshold. An improved division method for the linear octree that only allocates memory to the non-blank nodes, is proposed, which improves storage and retrieval efficiency for the point clouds. Meanwhile, the damage-occurrence regions are determined according to Hausdorff distances. Using a triangular mesh, damaged regions can be identified and measured in order to determine the relic's total damaged area. Results demonstrate that this method can effectively detect gold foil damage in stone carvings. The identified surface area of damaged regions can provide the information needed for subsequent restoration and protection of relics of this type.

“…Therefore, the environmental monitoring and investigation with SAR data is used to identify spatial and temporal patterns in the characteristics of the resource to better enable assessment of changes over time. Many studies on SAR interferometry (Jarosz, 2003;Perski, 2000;Stow, 1997, Paradella, 2015 have revealed that significant subsidence has occurred inside the mining operation with some limitations over rapidly changing area (showing low coherence) (Strozzi, 2002;Chen, 2013). Conventional DInSAR applied in the surface deformation monitoring has been associated with the geodynamic events and mining activities (Modoni, 2013;Tripolitsiotis, 2014).…”

ABSTRACT:The satellite data provide a new perspective to analyse and interpret environmental impact assessment as function of topography and vegetation. The main goal of this paper is to investigate the new Staring Spotlight TerraSAR-X mode capabilities to monitor land degradation in Rosia Jiu opencast area taking into account the mining engineering standards and specifications. The second goal is to relate mining activities with spatio-temporal dynamics of land degradation by using differential Synthetic Aperture Radar interferometry (DInSAR). The experimental analysis was carried out on data acquired in the LAN_2277 scientific proposal framework during 2014-2015 period. A set of 25 very height resolution SAR data gathered in the VV polarisation mode with a resolution of 0.45 m x 0.16m and an incidence angle of 37 0 have been used in this study. Preliminary results showed that altered terrain topography with steep slopes and deep pits has led to the layover of radar signal. Initially, ambiguous results have been obtained due to the highly dynamic character of subsidence induced by activities which imply mass mining methods. By increasing the SAR data number, the land degradation assessment has been improved. Most of the interferometric pairs have low coherence therefore the product coherence threshold was set to 0.3. A coherent and non-coherent analysis is performed to delineate land cover changes and complement the deformation model. Thus, the environmental impact of mining activities is better studied. Moreover, the monitoring of changes in pit depths, heights of stock-piles and waste dumps and levels of tailing dumps provide additional information about production data.
