Federated Giovanni: multi-sensor data sharing and visualization

Abstract:

Giovanni (Geospatial Interactive Online Visualization and Analysis Interface) has long been a popular tool among remote sensing data users of the Goddard Earth Sciences Data and Information Services Center (GES DISC). It supports about two dozen visualization and analysis services that enable interactive exploration of the data, which is a key early step in data analysis. Giovanni brings usability, a low learning curve, and the ability to provide informative visualizations without downloading large volumes of data to the user's location.

Federated Giovanni allows each data center to configure and deploy its own Giovanni and curated data catalog, while allowing various Giovanni instances to share data from each other for data intercomparisons. Providing Giovanni’s capabilities to other data providers through federation will allow a dramatically larger number of distributed datasets to be made available for interactive data exploration and inter-comparison. This capability is particularly beneficial to science researchers studying data from multiple sensors and satellites. In this presentation, we will describe the architecture as well as the process of curating and sharing Giovanni data catalogs to enable inter-comparison of data from multiple sensors.
