The Helioviewer Project: discovery for everyone everywhere There is an ever increasing amount of solar and heliospheric data gathered from multiple sources such as space-based facilities and ground based observatories. There are also multiple feature and event catalogs arising from human and computer based detection methods. The Helioviewer Project is developing a suite of technologies to allow users around the world to visualize, browse and access these heterogeneous datasets in an intuitive and highly customizable fashion.
Helioviewer technologies are based on the JPEG2000 file format, an extremely flexible format that allows for the efficient transfer of data (and meta-data, such as FITS keywords) between client and server. Rather then having to download an entire image and then examine the small portion- for example, an active region - that you are interested in, the JPEG2000 file format lets you preferentially download only those portions you are interested in. This dramatically reduces the amount of data transferred, making possible responsive and flexible scientific discovery applications that can browse populous archives of large images, such as those from the Solar Dynamics Observatory.
In addition, the Helioviewer Project is designed to be flexible and extensible to data sources as they become available. Helioviewer.org (www.helioviewer.org) works seamlessly with the Virtual Solar Observatory (VSO) whilst an application programming interface (API) is being developed for interaction with the Solar Dynamics Observatory Heliophysics Event Knowledgebase.
After a short introduction to the underlying technology, a live demonstration of the web application www.helioviewer.org will be given. We will also comment on other client applications (Jhelioviewer, a Java-based browse tool), and the application of Helioviewer technology to existing and future solar and heliospheric data and feature/event repositories. This project is funded by NASA VxO and LWS awards and an ESA science award.
