Geospatial image data obtained by satellites and aircraft are increasingly important to a wide range of applications, such as disaster management, climatology, and environmental monitoring. Because of the size of the data and the speed at which it is generated, computing spatio-temporal aggregates over geospatial image data is extremely demanding. Due to the special characteristics of the data, existing spatio-temporal aggregation model and evaluation approaches are not suitable for computing aggregates over such data. In this paper, we outline the key challenges of computing spatio-temporal aggregates over streaming geospatial image data, and present three goals of our research work. We also discuss several preliminary results and future research directions.
