9. Slide 9 19th EGOWS, Ljubljana, 9 - 12 June 2008 9 Magics++ - MagML XML based format to describe Magics++ plots Descriptive, not procedural some support of variables and global definitions No need for (re-)compilation magml interpreter program processes a MagML file and produces output graphics Interpreter can be easily called in user code Description close to Metview’s icon convention Can be integrated into more complex XML request descriptions

10. Slide 10 19th EGOWS, Ljubljana, 9 - 12 June 2008 10 Magics++ - MagML usage MagML is very popular with users Main aim is the large scale automatic production of plots MagML enables easy use of new features of Magics++ to make it more attractive for producing web output -Generating meta information / JavaScript code to support interactivity of web output -Layers -New formats: SVG, GIF, PDF, KML Used in this way in the Plot-On-Demand project at ECMWF Ideal as backend for web interfaces with static layout and visual properties but changing data

19. Slide 19 19th EGOWS, Ljubljana, 9 - 12 June 2008 19 Metview 3.11 – developments Support for Grib 2 through migration from gribex to GribAPI -Meant many internal changes -Internally we still convert Grib 2 to Grib 1 for visualisation only Support for inline C/C++ in Metview Macro (same as inline Fortran) New features to support ECMWF’s Observations DataBase (ODB) -Allows examining and reading for visualisation and processing -Only released inside ECMWF

20. Slide 20 19th EGOWS, Ljubljana, 9 - 12 June 2008 20 News Magics++ updates Metview updates Metview 4 Other developments

21. Slide 21 19th EGOWS, Ljubljana, 9 - 12 June 2008 21 Metview 4 - Aims Take full advantage of features from support libraries: -Magics++ -GribAPI -New Interpolation library -Terralib (INPE / Brazil) Address issues reported by users: -More options to work with satellite data -Enhanced Macro editor -Easier installation (e.g. binary distribution) -Integrate Magics++ tools (MagML, Metgrams) -Improved NetCDF support

22. Slide 22 19th EGOWS, Ljubljana, 9 - 12 June 2008 22 Metview 4 - improvements Magics++ and Metview will both use C++ -Interface between both is generated from the same XML description files as the Fortran and MagML interface is More sharing of code between Magics++ and Metview More input and output formats (Magics++) Improvements in user interactivity, such as layers -The ability to dynamically toggle certain graphical objects, such as contour labels and maxima/minima Querying the properties of graphical objects displayed on screen Generate MagML for plot-on-demand (web)

23. Slide 23 19th EGOWS, Ljubljana, 9 - 12 June 2008 23 Metview 4 - status Currently in alpha status User can switch between current, MAGICS 6 based plot module or new, Magics++ based plot module New plot module, using OpenGL, is working as first prototype -Better fonts -Improved zooming functions Thanks to modular architecture, Metview 3 modules continue to work alongside new Metview 4 modules Some Metview 3 modules might be removed later or redirected to a ‘translator’ to call a respective new module

24. Slide 24 19th EGOWS, Ljubljana, 9 - 12 June 2008 24 Metview 4 - new display

25. Slide 25 19th EGOWS, Ljubljana, 9 - 12 June 2008 25 Metview 4 - Next steps Start having users testing Metview 4 this summer -Mainly for new ODB / NetCDF features Release future test version of Metview including new Metview 4 modules Currently non-invasive work on Metview 3 Review of ‘old’ features - some might be rewritten or even removed Consider new GUI toolkit additional to Motif - stepwise transition First release in 2009
