11th Workshop on
Meteorological Operational Systems
 12th – 16th November 2007
at ECMWF, Reading, UK
 Speakers were invited
to report on “new trends in
meteorological visualisation
applications”
 Focus was on web services
and applications. We had discussions on how useful
Rich Internet Applications can be.
 Calls for a separate Workshop to discuss OGC web
standards / services

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

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

Magics++ - next steps
 Start testing new ECMWF interpolation library
 Develop features to support Metview 4
 “Style sheets” for data types / products
(possible replacement for specification groups)
 Investigate streamlines
 Introduce new projections (e.g. tephigrams)
 Investigate advanced GIS features (e.g. shaded relief
maps)

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

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

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)

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

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

WMO symbols fonts (1)
 Wmo.jhf (Java - VisAD)
 Suggestion for a Wiki
 ERSI font files
 Disadvantages: inclusion in vector formats, no layouts
 Possible commercial fonts
 Thanks for all your feedback!
Slide 27
19th EGOWS, Ljubljana, 9 - 12 June 2008

WMO symbols fonts (2)
 We test now TTF fonts in Magics++
 We test Pango as the layout engine
 Inclusion in vector formats (SVG, PS) a real problem
 We still look for a ‘full’ set of WMO symbols
 We will keep you informed about our progress!

OGC web services
 Web standards defined by Open Geospatial Consortium
 WMS - Web Map Service
- Examples: Google Earth
 WFS - Web Feature Service
- Retrieving or altering feature descriptions
 WCS - Web Coverage Service
- Provide ‘coverage objects’
 File formats
- GML
- KML (Google Earth)
Slide 29

OGC services - our plans
 Support KML output in Magics++ / Metview 4
- Start Google Earth from Metview
 Support of OGC description of projections
- Terralib supports EPSG codes
- Possibility to use Magics++ to build WMS service
 Enable definition of WMS request and import of results
 Add support for GML and WCS as input?
 There are plans to hold a Workshop about OGC web
services end of November 2008! Slide 30
