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.
Java and jhelioviewer movie#
If request parameters `verbose` is set to `true` and `jpip` is omitted or set to `false`, the reponse is a JSON object containing an HTTP-protocol link to the JPX movie plus the timestamps of each frame a message if the value of `cadence` was overridden by the server.Space missions generate an ever-growing amount of data, as impressively highlighted by the Solar Dynamics Observatory's expected data rate of 1.4 Terabyte per day.
If no cadence is specified, the server will attempt to select an optimal cadence. The desired amount of time (in seconds) between each frame in the movie. Optionally return a JPIP URI string instead of the binary data of the movie itself, or instead of an HTTP URI in the JSON response (if `verbose` is set to `true`). If set to `true,` the JSON response will include timestamps for each frame in the resulting movie and any warning messages associated with the request, in addition to the JPX movie file URI. Currently, only JPX image series support this feature.
Generate a `linked` JPX file containing image pointers instead of data for each individual frame in the series. Can be specified in lieu of the `observatory`, `instrument`, `detector`, and `measurement` parameters.
