The aim of this project is the development a large data warehousing and analysis tool for air traffic management (ATM) research that can be accessed by users through intuitive web-based User Interface (UI). DSAT is designed to support requirements of a variety of ATM users, from data handlers interested in maintaining data quality to researchers looking for patterns in acquired data to analysts who need to compute basic metrics on a particular subset of data to managers who need to visualize and report results from a particular analysis. DSAT is a multi-level, multi-objective tool for big data analysis that extracts ATM data from a variety of ATM data stores and prepares it for holistic analysis within an actionable timeline. At this time no turnkey software exists that supports all levels of data handling from storage to reporting for ATM research DSAT serves the purpose of a variety of users through a set of tools customized to handle different types of ATM analysis for different types of users. In particular, DSAT is a (i) data storage tool, (ii) data analysis tool, and (iii) visualization and reporting tool all wrapped into one.
