Interactive Science and Geospatial Visualization Tools for HUBzero Science Gateways

Sign up or log in to save this to your schedule and see who's attending!

HUBzero is a powerful, open source software platform for creating dynamic science gateways that support scientific research and educational activities (hubzero.org). Used by communities such as nanotechnology, earth sciences, data curation, and healthcare, it is a proven framework for building science gateways, and a key part of many organizations’ cyberinfrastructure. There are more than 60 science gateways powered by HUBzero, totaling more than 2 million visitors each year. Among capabilities for collaboration, project work, and publishing, the HUBzero platform also provides an application framework for developing and deploying interactive computational tools. Historically these tools have been oriented toward mathematical modeling and simulation. However, currently there is a growing emphasis on interactive data visualization and exploration applications that are not as computationally intense and from which users expect a dynamic experience. Recent additions to HUBzero that further enhance the interactive and collaborative scientific discovery capabilities of the platform support this need. The addition of the Jupyter Notebook and RStudio Shiny web application frameworks enable the creation of dynamic applications supporting both researchers seeking on-the-fly modifications of computation models and data views but also instructors seeking to develop course materials with significant practical components. Using a HUBzero hub, researchers and educators can publish their notebooks and applications to a wide audience of people with similar interests. Further, the HUBzero middleware provides a secure place to share notebooks and applications which can also be disconnected from and reconnected to as a user changes locations or client computers. The GABBs (Geospatial Data Analysis Building Blocks) project independently funded by the NSF, is an example of the new breed of interactive data analysis and visualization needs. The project adds both general-purpose as well as geospatial-specific software modules to HUBzero. The nature of the integration of these modules with HUBzero lends itself to similar enhancements for other science gateways leveraging HUBzero.
This tutorial will start with a brief overview of HUBzero, but the focus will be on these recent enhancements to the platform. We will walk through the salient features of the Jupyter and Shiny frameworks through a series of hands-on activities. The latter half of the tutorial will describe the new data management and interactive visualization capabilities built by the GABBs project. Additional hands-on activities will walk attendees through the management of geospatial data, demonstrations of the metadata capture and preview capabilities and toolkits that enable the creation of interactive geospatial visualizations with minimal programming.
Prerequisites: this tutorial has a significant hands-on component, so you must bring your own laptop to participate fully. It would be best to install Oracle VM VirtualBox on your laptop beforehand. We will be distributing VMs for use on USB sticks.
