    Helioviewer Talk at the SDO-AIA science Meeting, 20-22 April 2009 - Presentation Transcript

    1. ADNET Systems, Inc. Helioviewer Discovery for Everyone Everywhere Jack Ireland & Helioviewer Team ADNET Systems, Inc. Thursday, May 28, 2009
    2. ADNET Systems, Inc. Helioviewer Discovery for Everyone Everywhere Desmond Amadigwe Jack Ireland Patrick Schmiedel George Dimitoglou Ben Karel Benjamin Wamsler Bernhard Fleck Daniel Müller Alen Agheksanterian Keith Hughitt Juan Pablo Garcia Ortiz Thursday, May 28, 2009
    3. The Helioviewer Project • Challenges - Huge amounts of data: - SOHO: ~0.2 Gbyte/day - SDO: ~1400 Gbyte/day - Large range of time & length- scales - Many different data products - Distributed archives - Multiple interest groups There are many distributed sources of information for one physical system - the heliosphere. J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    4. The Helioviewer Project • Goals - Enable efficient data browsing and visualization for users everywhere - Transparent access to multiple distributed archives e.g. HEK, VSO, GOES flare catalogs, ground based data - Extensible, open design that requires a minimal effort to join Create a discovery infrastructure that allows users to explore the heliosphere as a physical system J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    5. Components • Image service - Database of images from multiple observatories - JPEG2000 compression scheme - many advantages - API to use service - open to all J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    6. Components • Image service - Database of images from multiple observatories - JPEG2000 compression scheme - many advantages - API to use service - open to all • Feature/Event service - A web service that interacts with multiple archives, e.g. HEK,VSO, GOES flare catalogs. - API to use service - open to all J.

Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    8. Image storage with JPEG2000 JPEG2000 = new wavelet-based compression standard Advantages: • Multiple resolutions [Images at different resolutions are automatically created during wavelet compression process] • Random image access [Selected parts + quality layers can be accessed] • Flexible file format [for metadata] • Well-suited for archives [lossless mode, “Compress once, decompress many ways”] J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    9. Image storage with JPEG2000 JPEG2000 = new wavelet-based compression standard Advantages: • Multiple resolutions multiple heliospheric [Images at different resolutions are automatically created during wavelet compression process] ✓ length-scales • Random image access [Selected parts + quality layers can be accessed] • Flexible file format [for metadata] • Well-suited for archives [lossless mode, “Compress once, decompress many ways”] J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009

    13. Remote Access to Image Data 40962 px image level 5 • JPIP = JPEG2000 5 level DWT level 4 Interactive Protocol level 3 • JPIP provides a client level 2 −server architecture for transmitting JPEG2000 level 1 imagery over networks • Can query arbitrary parts, quality levels of images and movies we need transfer only those wavelet movie • IDL, Solarsoft, Kakadu coefficients required for the requested cube JPEG2000 libraries field of view and time J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    14. SDO-AIA image data • JPEG2000 compression by a factor 16 yields reasonable browse EIT images. • 16x compression @ 1 minute cadence yields ~ 0.3 Tb/year/wavelength. • Keep most recent data (1-3 mo.) at full cadence? • Permanent library of browsable images for entire mission. • Very easy to concatenate JPEG2000 files to make movies and serve them remotely. J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
    15. Feature/event service • Works with heterogenous feature/event services and archives, e.g., HEK, VSO, stand- alone catalogs (e.g., GOES) • Transparent to the user • API is open to other developers • Many types of meta-data are handled J. Ireland ADNET Systems, Inc. Thursday, May 28, 2009
