Collaborative Architecture of Wide Area Natural Disaster Observation System

Heterogeneous systems” collaboration strategy is important for natural disaster observation. In this paper, we discuss the collaborative architecture of integrated observation system using satellite remote sensing, $V$ nmanned swarm system, Internet of Things (IoT), and Geographic Information System (GIS) technologies. We concern three issues: inter-domain and intra-domain systems' collaboration mechanisms, heterogeneous communication network, and system function modularization. On the base of the proposed architecture, we perform a series of satellite and UAV remote sensing and modeling experiments, then we develop a data visualization system based on GIS and observed data. We propose an unmanned swarm observation algorithm and perform a series of simulation experiments, also we develop an initial end-edge-cloud system for unmanned swarm observation. The proposed architecture provides better system scalability in complex emergency environment.
