JHelioviewer software is open source, platform independent and extendable via a To the challenge of efficiently browsing petabyte-scale image archives.

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. In effect, it is a virtual observatory," says Müller.Download a PDF of the paper titled JHelioviewer - Time-dependent 3D visualisation of solar and heliospheric data, by D. "The goal of JHelioviewer, and the Helioviewer Project as a whole, is to offer intuitive interfaces to large datasets from many different sources. It also allows data to be annotated, say, solar flares of a particular magnitude to be marked or diseased tissues in medical images to be highlighted. This is because JHelioviewer does not need to download entire datasets, which can often be huge - it can just choose enough data to stream smoothly over the Internet. The code can even be reused for other purposes it is already being used for Mars data and in medical research. It is open-source software, meaning that all its components are freely available so others can help to improve the program. JHelioviewer is written in the Java programming language, hence the 'J' at the beginning of its name. This is an interactive visual archive of the entire SOHO mission." With JHelioviewer, everyone can do this in minutes. "Before, it took hours to combine images from different telescopes to make a movie of the Sun for a given period. "We wanted to make it easy to view solar images from different observatories and instruments, and to make it easy to make movies," says Daniel Müller, ESA SOHO Deputy Project Scientist. They can export their finished movies in various formats, and track features on the Sun by compensating for solar rotation. Using this new software, users can create their own movies of the Sun, colour the images as they wish, and image-process the movies in real time. JHelioviewer 272 subscribers 28K views 12 years ago This video tutorial shows you how to use JHelioviewer, a new open-source visualization software for the Sun. The downloadable JHelioviewer is complemented by the website, a web-based image browser. More than a million images from SOHO can already be accessed, and new images from NASA's Solar Dynamics Observatory are being added every day. 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. JHelioviewer is new visualisation software that enables everyone to explore the Sun.
