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.

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

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”]

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

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.

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
