Giovanni: A Web Service Workflow-Based Data Visualization and Analysis System

Abstract

NASA's Goddard Earth Sciences Data and Information Services Center has developed the Goddard Interactive Online Visualization ANd aNalysis Infrastructure or “Giovanni,” an asynchronous Web-service-based workflow management system for Earth science data. Giovanni has been providing an intuitive and responsive interface for visualizing, analyzing, and intercomparing multisensor data using only a Web browser to scientists and other users. Giovanni supports many types of single- and multiparameter visualizations and statistical analyses. The interface also provides users with capabilities for downloading images and data in multiple formats. Giovanni supports open and standard data protocols and formats. Finally, Giovanni provides users with a data lineage that describes, in detail, the algorithms used in processing the data including caveats and other scientifically pertinent information.
