To meet the growing demand for socioeconomic development, a large amount of groundwater is extracted from confined aquifers worldwide. The North China Plain has experienced considerable depletion and subsidence during past six decades. In this study, we use Sentinel-1A/B SAR images 2015 to 2020 map ground Tianjin–Langfang area. Three subsiding zones centered at Guangyang, Wuqing–Bazhou, Jinghai are identified with maximum rates 98.1, 121.8, 104.7 mm/yr. Seasonal long-term signals separated...
Continuous Global Positioning Systems (GPS) coordinate time series with a high spatiotemporal resolution, and provide great opportunity to study their noise models common mode errors (CMEs), thus making it possible detect analyse characteristics of tectonic non-tectonic signals in series, further estimate reliable accurate velocity field crustal movement region by removing CMEs using the optimal model. In this paper, we used GPS from Crustal Movement Observation Network China (CMONOC) an...
The automatic modeling of as-built building interiors, known as indoor reconstruction, is gaining increasing attention because its widespread applications. With the development sensors to acquire high-quality point clouds, a new scheme called scan-to-BIM (building information modeling) emerged well. However, traditional process time-tedious and labor-intensive. Most existing reconstruction solutions can only fit specific data or lack detailed model representation. In this paper, we propose...
This paper proposes a multi-temporal image change detection algorithm based on adaptive parameter estimation, which is used to solve the problems of severe interference coherent speckle noise and retention detailed information about changing regions in synthetic aperture radar remote sensing images. The area initial differential has local consistency global prominence. By detecting significant locate similar areas, outside can be eliminated. use hierarchical FCM clustering automatically...
Passive location and tracking (PLAT) of a moving emitter can be implemented by multi-sited observers or single maneuvering observer using DOA (direction arrival) measurements only. The principle method passive non-maneuvering TOA (time are presented described. Computer simulation PLAT in two dimensional plane was implemented. It shows that convergent accurate data obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
For the development of a global navigation satellite system (GNSS), third generation BeiDou Navigation Satellite System (BDS-3) achieved full constellation for worldwide service on 23 June 2020. The new signals, B1C and B2a BDS-3, further enhance compatibility interoperability between different GNSSs. In this study, we first assessed quality all signals in BDS-3/GPS/Galileo. Then, to achieve among BDS-3/GPS/Galileo, inter-system bias (ISB), which appears if an difference exists two GNSSs,...
