Earth Observation refers to the systematic monitoring and observing of the Earth's surface and atmosphere from a distance, using various sensors and remote sensing technologies. These technologies include, but are not limited to, satellite remote sensing, aerial photography, ground observation stations, and unmanned aerial vehicle (UAV) remote sensing. The purpose of Earth Observation is to collect data on the physical, chemical, and biological characteristics of the Earth to better understand the changes and dynamics of the Earth system, as well as the impact of these changes on human society and the environment. Earth Observation technologies enable a more comprehensive understanding of the patterns of change within the Earth's systems.

In the context of global challenges such as environmental issues, energy concerns, and disasters, Earth observation systems with global operational capabilities offer unmatched advantages over conventional methods of addressing these issues. The applications of Earth Observation are extensive and include, but are not limited to, resource surveys, environmental protection, climate change research, disaster monitoring, and emergency management. These applications play an active role in promoting socio-economic development and improving the quality of human life.

This Research Topic is dedicated to building a communication bridge for researchers, aiming to share and discuss the latest theoretical research, profound insights, and perspectives, technological achievements, methodological innovations, and the promotion of application practices in the field of Earth observation. It seeks to explore in-depth applications in resource surveys, environmental protection, and ecological environment assessment, and to jointly plan new developments in imaging spectroscopy Earth observation technology. We warmly welcome the sharing of research findings from theoretical studies, numerical simulations, and experimental simulations.

The content of the articles can cover a wide range of topics, including but not limited to:
• Earth perception theory and technology;
• Collaborative fusion technology;
• Ecological and environmental protection;
• Disaster identification and prediction;
• Mineral resource monitoring;
• Hydrological surveys;
• Soil and water conservation and sustainable development;
• Land resource management;
• The application of artificial intelligence in Earth observation.
