The NRL Geospatial Hub for ocean sensor processing and collaboration

Abstract

Abstract-The Naval Research Lab Geospatial Hub, or GHub, provides a rapidly deployable, scalable platform for geospatial product collaboration. The GHub is not only a content management system with a web-based interface, but also hosts a variety of content-driven geo-services for tightly integrated, but loosely coupled tool interaction. The GHub presents a rich SOAP API to allow third party tools to build custom integration based on need. The contentdriven presentation of data in GHub makes it an ideal element for common information space architectures. The design of the GHub data store is especially suited to heterogeneous data types, such as those found in sensing of the ocean environment. By building tool-level integration with GHub, an architecture inherits peer-to-peer data sharing, disconnection robust synchronization between GHub nodes, a high-performance tile-based map server, and built-in product versioning.
