This DIBBs implementation project develops geospatial data analysis building blocks (GABBs) to fill in a gap in the HUBzero Scientific Collaboration Platform to meet the needs for  researchers and educators to create and share geospatial data sets and computational tools interactively on the web. The project builds upon open source geospatial software and tools that have been developed by IT experts and validated by the science community, and brings such capabilities to the masses so that non-GIS specialists can create and deploy online, interactive geospatial tools with open source software. 

The project will produce GABBs software components, i.e., building blocks, as part of the future HUBzero open source releases and add-on packages. The deliverables include:

  • Data management: easy-to-use tools and web services for users to self-manage, annotate, share, visualize and publish data, with special support for geospatial data (automatic metadata extraction, quick view, map layers, etc)
  • Visualization: Extended Rappture Toolkit and map library Application Program Interfaces (APIs) to support rapid creation and deployment of GIS-enabled, interactive online tools
  • Applications from scientific use cases of modeling, data analysis and visualization to demonstrate the general applicability of the GABBs software 
  • Public availability of GABBs software as downloadable virtual machines (VMs), Amazon Marketplace Instance (AMI), and packages through open source releases. Project results will be presented and published  at scientific conferences, workshops proceedings and journals.
