Because changes in the Earth's environment have become major global issues, continuous, longterm scientific information is required to assess global problems such as deforestation, desertification, greenhouse effects and climate variations Global change studies require understanding of interactions of complex processes regulating the Earth system Space-based Earth observation is an essential element in global change research for documenting changes in Earth environment It provides synoptic data for conceptual predictive modeling of future environmental change This paper provides a brief overview of remote sensing technology from the perspective of global change research
