Liquefied natural gas (LNG) storage tanks are an essential infrastructure for national energy security, and the monitoring of their integrity is the basis for ensuring the regular operation of storage tanks. Existing monitoring methods do not reflect changes in storage tanks well because most monitoring methods are based on a technical approach that allows only one type of monitoring data to be obtained, which does not give comprehensive monitoring results. In this study, we incorporate control measurements, light detection and ranging (LiDAR), unmanned aerial vehicle (UAV) photogrammetry, thermal infrared camera monitoring, interferometric synthetic aperture radar (InSAR), and other techniques. An integrated air–space–land multisource remote sensing monitoring scheme is proposed, and the scheme’s feasibility is verified through actual measurements, providing strong support for subsequent, efficient, and all-around monitoring.
