Abstract: Computer-based systems are described that afford the ability to associate a travel related object with a travel relate event and/or other travel related object. The system enables the acquisition, integration and management of data supplied by multiple, heterogeneous sources; single and multi-level exception handling, error correction, data enhancement, and data prediction; and fine-grained control of the distribution, access and display of this data to multiple users and non-users of the system. The system supports both consumer-facing constructs (e.g., applications that allow passengers to track flight and flight-specific information), and supra-management system-facing constructs (e.g., advancements, enhancements and augmentations of and for the management of the National Airspace System or airport ground traffic systems).

Abstract: Embodiments of the invention enable the display of objects in relation to each other through the use of multiple layers. The display can be refreshed without refreshing the screen; only individual layers requiring updating are refreshed.
