  3. Overall Goals • Provide a replacement for the current CASA Viewer • Maintain functionality and meet challenges • Plan for long-term sustainability

  4. Visualization Challenges • Big Data (50 GB to 1 TB image cubes) • Interactive visualization • Transport from archive • Extensibility and maintenance • Enabling community development • Connection to HPC

  5. Fusing Two Approaches CASA Viewer CyberSKA Viewer

  6. Two Worlds CyberSKA Viewer CASA Viewer • Handles Big Data • Fully-featured • Web-enabled • Meets ALMA use cases • Good user experience • Well-developed analytics • Expert user-base

  7. None of the Above • Easy maintenance • Extensibility • Fostering community contributions • Leverage HPC

  13. New Button Visualize Data

  14. Timeline Response to Architecture review and Risk Feature Build-out (features, Retirement performance) Hand- off 2014-03 2014-10 2016-04 2016-09 Expert Community Review Review

  15. Public Release Available with Development Guides https://github.com/Astroua/CARTAvis

  16. Application Priorities • Performance and Cleanup • Plone Documentation • Image export • WYSIWYG (90%) • Journal quality (export to file bundle and python script) • Interactive cleaning functionality

  17. Sunsetting Project development will handoff (next week!) to: • CASA group for ongoing development. ALMA CASA Development Center in Taiwan. EWR to remain on as Project Scientist. • NRAO Archive group for ongoing integration • ALMA Archive group once NRAO work is done

  18. Lessons Learned • Software project management is hard and time estimates were optimistic (esp., architecture) • Integration was effective through partnership with NRAO and the CASA software group • User testing essential but happened too late • Currency fluctuations became a major risk
