- Abstract
Urban complex is the basic unit of urban politics, economy and social life, and space remote sensing dynamic monitoring for urban complex is an efficient and accurate technical method. A space remote sensing dynamic monitoring system for urban complex is proposed and constructed from the aspects of application demand, technical method, remote sensing products, management release, etc. Using the system, the construction progress and surrounding water environment monitoring of the urban complex of Huoshenshan Hospital and Leishenshan Hospital are carried out. The construction progress of Huoshenshan Hospital and Leishenshan Hospital is monitored by high-resolution optical satellites such as Gaofen-2, Jilin -1 and Pleiades, which is identical with the construction progress in the news report and the officially published hospital area. The construction intensity of Huoshenshan Hospital is monitored by the high-resolution night light satellite Jilin-1, most areas of the construction plant are under high-intensity construction at night. The water environment around Huoshenshan Hospital and Leishenshan Hospital is monitored by the hyperspectral satellite Zhuhai1, the construction process has no significant impact on the surrounding water environment. The surface stability of Huoshenshan Hospital and Leishenshan Hospital before construction is analyzed by the high-resolution radar satellite Sentinel-1A, there is no obvious surface subsidence in the construction area of Huoshenshan Hospital, and there are different degrees of surface subsidence signals in the surrounding areas of Leishenshan Hospital. In the critical period of fighting against the coronavirus disease 2019 (COVID -19) , it has met the public’s attention needs and plays a certain role in stabilizing social mood. A retrospective monitoring of the collapse of Xinjia hotel in Quanzhou is carried out to provide data reference for accident liability analysis. The deformation of Xinjia hotel is mainly caused by the south wall, and the foundation settlement is not obvious. This result is consistent with the fact that the hotel collapses to the south, and the main reason for the collapse is the instability of the internal structure of the building, rather than the uneven ground settlement. The effectiveness of the system is verified.
