Diana is the core visualisation tool for StormGeo and is based on latest release of DIANA from MET Norway (Norwegian Meteorological Institute) and is distributed under the GPL license. See gpl.txt for details concerning the GPL license.
Diana is a graphical viewer and editor developed for use with meteorological and oceanographic data. It uses OpenGL and/or Qt for the graphics and Qt for the user interface.
Diana shows fields, observations and satellite and radar images on a map. 2D-trajectories can be computed from wind and ocean current fields. The tool also displays vertical profiles (soundings), vertical crossections, and wave spectrum data in separate windows, all from preprocessed data. Preprocessing software is however not a part of Diana. The editor tools consist of a field editor and a drawing tool for fronts, symbols and area types.
Diana supports multiple languages via the Qt Linguist system. Additional languages can be added by preparing new diana/lang/diana_XX.ts files (using the Qt Linguist program).
In addition to the interactive tool, there is also a command line version of Diana for batch plotting (bdiana). This can be built against embedded versions of the Qt libraries in order to run on systems without displays, such as servers.
