Moving Object Database Technology for Ad-Hoc Querying and Satellite Data Retrieval of Dynamic Atmospheric Events

Abstract

Abstract—Existing state-of-the-art and web-based weather event information portals, data archives, and forecast services provide excellent subsetting and visualizations of weather events and satellite sensor measurements. However, users only obtain limited, simple, and hard-coded query, retrieval, and analysis capabilities from these sources. One non-existent but desirable capability is the accurate and efficient ad-hoc querying of the trajectories of dynamic atmospheric events (e.g., tropical cyclones, hurricanes) as well as the efficient retrieval of Earth science satellite sensor data for these events based on ad-hoc, user defined criteria and the event trajectories. In this paper, we describe our current work and progress in the development of a sophisticated framework based on the moving objects database technology for ad-hoc querying and retrieval of atmospheric events and their associated satellite measurements. Such a capability is extremely important to scientists who process sensor data of atmospheric events for statistical analysis and scientific investigation.
