![]() JHelioviewer is part of the ESA/NASA Helioviewer Project. Faulting application name: JHelioviewer.exe, version: 0.0.0.0, time stamp: 0x5e5edc79 Faulting module name: kdua7AR.dll, version: 0.0.0. For further information about the project, contact Daniel Müller (Daniel.Mueller esa.int). JHelioviewer is being developed as open-source software by the ESA JHelioviewer Team.

These features minimize the data volume transmitted while maximizing its usability. The JPEG 2000 Interactive Protocol (JPIP) enables serving data in a highly compressed, quality-progressive, region-of-interest-based stream. JPEG 2000 offers many useful new features and has the potential to revolutionize the way high-resolution image data are disseminated and analyzed. Solar and Heliospheric Observatory, SOHO), multiple viewpoints (Solar TErrestrial RElations Observatory, STEREO), and returning large amounts of data (Solar Dynamics Observatory, SDO). ![]() JHelioviewer is visualization software for solar image data based on the JPEG 2000 compression standard. Solar observatories are providing the world-wide community with a wealth of data, covering wide time ranges (e.g. However, work on JHV version 2 continues. The project is in maintenance mode and issues are fixed on a best-effort basis. Downloads are still available from and functional. This poster will illustrate the new and expanded functionality of JHelioviewer and highlight the advantages of JPEG 2000 as a new compression standard for solar image data.This repository contains the no longer actively developed version 3 of JHelioviewer. Currently focused on solar physics data, JHelioviewer can easily be adapted for use in other areas of space and earth sciences. The random code stream access of JPIP minimizes data transfer by streaming image data in a region-of-interest and quality-progressive way, while OpenGL enables rapid hardware-accelerated image processing and rendering. I can see it daily using this special software designed by the ESA (european space admistration). JHelioviewer uses the JPEG 2000 Interactive Protocol (JPIP) and OpenGL. Location of discovery: Earths Sun, 45-45 degree Source software: I found this black triangle UFO on our sun a few months ago and I am still watching it. JHelioviewer is a cross-platform application that offers movie streaming, real-time frame-by-frame image processing, feature/event overlays and will enable users to access SDO science data via a VSO interface. ![]() JHelioviewer will make the vast amount of SDO images available to the worldwide community in this format, which is already being used for all SOHO images. Using the very efficient lossy compression mode of JPEG 2000, a full-size SDO image can be compressed to 1 MByte at good visual quality for browsing purposes. To address this challenge, we have developed JHelioviewer, a JPEG 2000-based visualization and discovery software for solar image data. For SDO, the former approach is prohibitive due to the shear data volume, while the latter does not do justice to the high resolution and cadence of the images. So far, the tools available to the scientific community either require downloading all potentially relevant data sets beforehand in their entirety or provide only movies with a fixed resolution and cadence. In order to fully exploit their data, scientists need to be able to browse and visualize many different data products spanning a large range of physical length and time scales. Space missions generate an ever-growing amount of data, as impressively highlighted by the Solar Dynamics Observatory's (SDO) expected return of 1.4 TByte/day.
