Developing Geospatial Data Analysis Building Blocks (GABBS)

Geospatial Data Analysis Building Blocks (GABBs) is an NSF-funded Data Infrastructure Building Blocks (DIBBS) project to create a powerful yet easy-to-use web-based system that provides the software building blocks allowing researchers. who are typically not a computer expert, to self-manage, curate, share, analyze, and visualize geospatial data for their research. This opens the way for rapid development of a variety of web-enabled interactive tools for probing and presenting geospatial data. The development of GABBS building blocks is driven by the requirements from several user communities, including hydrologic modeling and data sharing, applied economics modeling workflow, meteorological data management and visualization, K-12 education tools, and high education course development with online modeling support. GABBs also integrate XSEDE resources, Globus, iRODS and other cyberinfrastructure support, enabling large scale computation and data capabilities for the user community. This poster will present the design and implementation of the GABBS software consisting of geospatial data management functions that are integrated into HUBzero’s Project data space, software and hardware based mapping libraries and map viewer widgets for geospatial tool development, and dynamic invocation of data analysis tools from the Hub Project data space.<div><br></div><div>Team members include: Larry Biehl, Rajesh Kalyanam, Rob Campbell, Betsy Hillery, Carolyn Ellis, Derrick Kearney, Leif Delgass, Kevin Wojkovich, Erich Huebner, Hou-Jen Ko, Nelson Villoria, Venkatesh Merwarde, Adnan Rajib, Jaewoo Shin, I Luk Kim</div> <div> <div> <div> <p> <br></p> </div> </div> </div

MyGeoHUB.org - An Open Platform for Geospatial Tool Development and Sharing

Geospatial data are present everywhere today with the proliferation of location-aware computing devices. This is especially true in the scientific community where large amounts of data are driving research and education activities in many domains. Collaboration over geospatial data, for example, in modeling, data analysis and visualization, must still overcome the barriers of specialized software and expertise among other challenges. Built using the HUBzero software, MyGeoHUB tries to address these needs by providing an open platform for geospatial tool development and sharing. It creates a geospatial data architecture that integrates spatial data management, mapping and visualization, and interfaces in the HUBzero platform for scientific collaborations. In addition to HUBzero’s built-in mechanism that supports self development and contribution of scientific tools, it also provides software building blocks including the geo-rendering enabled Rappture toolkit, a generic Python mapping library, geospatial data exploration and publication tools, and an integrated online geospatial data management solution. This poster will showcase how MyGeoHUB enable researchers and educators to self-manage their scientific data, rapidly create GIS-enabled tools, share geospatial data and tools on the web, and build dynamic workflows connecting data and tools, all without requiring significant software development skills, GIS expertise or IT administrative privileges. <div><br></div><div>Team members: Larry Biehl, Rajesh Kalyanam, Rob Campbell, Betsy Hillery, Carolyn Ellis, Derrick Kearney, Leif Delgass, Kevin Wojkovich, Erich Huebner, Hou-Jen Ko, Nelson Villoria, Venkatesh Merwade, Adnan Rajib, Jaewoo Shin, I Luk Kim</div

MyGeoHub Geospatial Gateway

<div> <div> <div> <p>MyGeoHub is a science gateway for researchers working with geospatial data. Based on the HUBzero cyberinfrastructure framework, it provides general-purpose software modules enabling geospatial data management, processing and visualization. Termed “GABBs” (Geospatial Data Analysis Building Blocks), these modules can be leveraged to build geospatial data driven tools with minimal programming and construct dynamic workflows chaining both local and remote tools and data sources. We will present examples of such end-to-end workflows demonstrating the underlying software building blocks that have also found use beyond the MyGeoHub gateway in other science domains. </p> </div> </div> </div
