摘要：Research in hydrology will often involve an analysis of complex natural and human systems. Such research includes both water resources (catchment-scale water budgets, snowmelt, supply and demand issues) and hazards analysis (flooding, channel erosion, impacts of urbanization). In recent years the wider access of geospatial satellite data to represent these systems, and development of tools and technologies to process this data has increased tremendously. As a result, hydrological research has become a frontrunner in the evolution of the geosciences into its current guise. This editorial summarizes some of the key geospatial satellite data sources and technologies being applied to hydrological research.
