JHelioviewer software is open source, platform independent and extendable via a To the challenge of efficiently browsing petabyte-scale image archives. The JPEG2000 standard offers useful new features that facilitate theĭissemination and analysis of high-resolution image data and offers a solution Release of JHelioviewer, the scientific functionality of the software has beenĮxtended significantly, and the objective of this paper is to highlight these Visualisation tool for solar data based on the JPEG2000 compression standardĪnd part of the open source ESA/NASA Helioviewer Project. To address these challenges, we have developed JHelioviewer, a From a scientist's perspective this poses three problems:Īccessing, browsing and finding interesting data as efficiently as possible.Īims. To download practically due to their size and download data rates available to In particular, the large volume of SDO data presentsĬhallenges: it is available only from a few repositories, and full-disk,įull-cadence data for reasonable durations of scientific interest are difficult Wealth of data, covering large time ranges, multiple viewpoints, and returning Solar observatories are providing the world-wide community with a Mueller and 11 other authors Download PDF Abstract: Context. Developed as part of the ESA/NASA Helioviewer Project, it provides a desktop program that enables users to call up images of the Sun from the past 15 years. In addition, the easy-to-use graphical user interface enables the general public and educators to access, enjoy and reuse data from space missions without barriers.Download a PDF of the paper titled JHelioviewer - Time-dependent 3D visualisation of solar and heliospheric data, by D. JHelioviewer is new visualisation software that enables everyone to explore the Sun. As part of the ESA/NASA Helioviewer Project, JHelioviewer offers intuitive ways to browse large amounts of heterogeneous data remotely and provides an extensible and customizable open-source platform for the scientific community. Besides viewing data, the browser provides third-party metadata and event catalog integration to quickly locate data of interest, as well as an interface to the Virtual Solar Observatory to download science-quality data. Users can view, manipulate, pan, zoom, and overlay JPEG 2000 compressed data quickly, without severe network bandwidth penalties. This solution enables users to access remote images at different resolution levels as a single data stream. We did so by deploying an efficient image encoding, storage, and dissemination solution using the JPEG 2000 standard. To address these challenges, we have developed JHelioviewer, an open-source visualization software that lets users browse large data volumes both as still images and movies. From a scientist's perspective this poses three challenges: accessing, browsing and finding interesting data while avoiding the proverbial search for a needle in a haystack. ![]() With such staggering data volume, the data is accessible only from a few repositories and users have to deal with data sets effectively immobile and practically difficult to download. The unprecedented torrent of data returned by the Solar Dynamics Observatory is both a blessing and a barrier: a blessing for making available data with significantly higher spatial and temporal resolution, but a barrier for scientists to access, browse and analyze them. ![]()
