Java and jhelioviewer software#

The JHelioviewer software does advanced data processing and visualisation therefore it works best on a reasonably recent computer with decent CPU and OpenGL graphics power, and memory. Information and support requests can be sent to Installing and Running Since JHelioviewer is still rapidly evolving, this document may not reflect entirely all the capabilities of the software. The events can be visualised on both the images and the timelines. Both the Heliophysics Events Knowledgebase and the COMESEP project provide the events. Several types of space weather related events can be displayed. The time interval displayed can be translated and zoomed freely. The timeline viewer shows one-dimensional and two-dimensional data. Field lines of the solar magnetic field calculated by a PFSS model can be displayed. Other projections are available, such as solar latitudinal or (log)polar. They can be rotated, translated, and zoomed in and out the sphere. The solar images can be projected on a sphere.

The viewer is able to display solar image data, and one-dimensional and two-dimensional solar timeline data. The JHelioviewer solar data visualisation tool has been overhauled with a strong focus for space weather usage. This project builds upon the infrastructure of ESA/NASA Helioviewer Project ( ) at all levels of the software stack, and significantly augments the capabilities of the JHelioviewer software ( ). 4000107325/12/NL/AK - High Performance Distributed Solar Imaging and Processing System - run at the Solar Influences Data Analysis Center (SIDC, ) of the Royal Observatory of Belgium (ROB) under the supervision of Space Environments and Effects section of ESA (ESTEC/TEC-EES, ). Space Weather JHelioviewer is an outcome of the ESA Contract No.

Java and jhelioviewer code#

The random code stream access of JPIP minimizes data transfer and can encapsulate meta data as well as multiple image channels in one data stream. The user interface for JHelioviewer is a multi-platform Java client that can both communicate with a remote server via the JPEG 2000 interactive protocol JPIP and open local data. Together with its web-based counterpart, JHelioviewer offers intuitive ways to browse large amounts of heterogeneous data remotely and allows users to search related event data bases. Currently focused on solar physics data, it can easily be adapted for use in other areas of space and earth sciences. To facilitate browsing and analysis of complex time-dependent data sets from multiple sources, we are developing JHelioviewer, a JPEG 2000-based visualization and discovery infrastructure for image data. 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.
